Mastering microcontrollers often feels like a dark art, but Myke Predko’s "123 PIC Microcontroller Experiments for the Evil Genius" serves as a definitive grimoire for aspiring engineers and hobbyists. This guide takes you from a "newbie" to a "PIC programming genius" through 123 graded experiments that build your skills from the ground up. Why This Book is a Staple for the "Evil Genius"
Unlike traditional textbooks that focus heavily on dry theory, this book is designed for the hands-on builder. It utilizes the Microchip PICkit 1 Starter Kit as its primary development platform, making it an accessible entry point for those without expensive lab equipment. Key Learning Paths Included:
The Foundation: Start with the basics of microcontroller architecture, focusing on the PIC16F684 and PIC12F683 chips.
Gradual Complexity: Each experiment builds on the previous one, covering LED patterns, sensor interfacing, and motor control.
Programming Dualism: The book explores both Assembly language and C programming, giving you a choice between low-level control and high-level efficiency. Highlights of the 123 Experiments
The projects range from simple household modifications to mischievous gadgets. Some standout experiments include:
Environmental & Security: Build a "Ghostly Doorbell" that plays spooky sounds or a "Talking Doormat" that greets (or warns) visitors.
Wireless Control: Learn RF communication by building a remote-controlled coffee machine.
Mischief Gadgets: Create an "Uncontrollable TV Remote" that randomly changes channels using infrared (IR) communication.
Industrial Skills: Master complex tasks like Ultrasonic distance-ranging, Stepper Motor control, and Pulse Width Modulation (PWM) for servos. Where to Find Verified Resources

He found the PDF by accident.
The file sat on a shadowed corner of a forum, its name a jumble of keywords: "123 pic microcontroller experiments for the evil geniuspdf verified." Maybe someone had meant to share a schematics list and instead left a breadcrumb. Elias clicked the link with the polite curiosity of someone who once built a blinking LED out of boredom and a scavenged kit. The download completed in thirty seconds. He opened the document and felt an old, familiar thrill — the smell of solder and cardboard, the hum of a cheap power supply.
The book inside was a paradox: clear, clinical instructions braided with a sly, winked humor. It promised projects that fit on a tabletop and into a mind: timers that whispered in Morse, a pair of infra-red eyes that tracked movement like a pet, a tiny synthesizer that could generate fog-horn sirens and lullabies. The tone was conspiratorial—“for the evil genius,” it said, as if schematics were spells and every transistor a rune.
He started small. Project 3: “Blinky.” A PIC microcontroller, an LED, a resistor, three lines of code. He wrote the words, uploaded. The LED blinked with a steady heartbeat. Someone from another room laughed; a colleague asked if he was still tinkering. Elias lied and said he was testing his laptop battery. The truth was softer: that blink let him remember the first time he learned to make things move with code — the first small victory after nights of failure.
With each experiment the world widened. Project 17 taught him to read pulses from a humidity sensor. Project 42 turned old headphones into a crude ultrasonic ranger that could measure distance in mouse-squeaks. A week blurred into circuits and coffee. The projects were simple but precise, each one a lesson in patience: solder joints must be clean, capacitors oriented correctly, comments in code preserved for the future.
It was when he reached Project 88 that the book wavered from playful to oddly intimate. The design was for a tiny beacon — not very powerful, but configurable. The notes suggested harmless uses: remote triggers for a camera, an indicator for a hidden key. In the margin, someone had written in a thin, hurried hand: “For when you need to say goodbye.”
Elias set the page down. He understood why someone might leave a line like that in a manual of circuits. Tools are never innocent; they are extensions of need. He had brought small devices into his life before — a gratified alarm to keep him from forgetting appointments, a motion-sensor lamp for late-night reading. This, though, felt dangerous in the way intentions become plans.
He kept going anyway.
Two weeks later, the lab smelled of flux. Elias had built a broadcast of little machines: a weather logger that uploaded readings to an offsite server, a set of RFID readers that could tell when a person entered a room, a dimmer that learned schedules and adjusted lights without instruction. The microcontrollers hummed together like a nervous system. The projects were clever, elegant, and obedient.
He began to see the shape of something bigger. The beacon from Project 88 could be repurposed, the UART port on Project 99 could be coaxed into talking to a neighbor’s unattended device. The user notes buried in the PDF’s margins — each a ghost of a prior reader — suggested experiments that weren’t in the official text. “Try it at 3.3V for longer life.” “Wrap it in tape if you’re outdoors.” “Works best when nobody’s watching.” The advice read like a map.
Late one night, when the city outside his window folded into a quiet grid of sodium lights, his program sent packets to an address he’d never meant to reach. It was not malicious — he had told himself that many times — but a test: ping, receive, respond. The reply was quick, an unexpected handshake from a device both mundane and intimate: a small home hub owned by a woman two buildings over. She had posted schematics of her own years ago, he realized; she left routers unlocked like open windows.
Elias stared at the screen. For the first time he felt the ghost of the phrase “evil genius” on the book’s cover. He imagined the possibilities, the old fantasies that had once been harmless: practical jokes that would make neighbors laugh, surveillance that could reveal who fed a stray cat each night, a mechanical kindness that would turn off gas valves after a forgetful neighbor’s stove was left on. But he also saw the slippery slope — into privacy invaded, into harm justified by convenience.
He typed a message to the woman two floors down, short and alive with awkward honesty. “I pinged your hub testing a project. Sorry. If you want, I can show you what I built — or take it down.” He clicked send, and his heart thudded with the same rhythm his first LED had kept.
Her reply came in under five minutes: “Please show me. Also, you should fix your power strip.”
They met the next morning on the cracked concrete between their buildings. She was shorter than he’d imagined, with a head full of silver threads and bright eyes that watched the world like a practiced engineer. Her name was Mira. She loved radios and had an old station wagon with parts stacked to the ceiling. She called herself a mad scientist with a smile.
He showed her the circuits. She took each board gently, as if handling small birds. “You didn’t do anything bad,” she said. “Curiosity is not a crime. Use matters.” She told him stories in return: a beacon she’d once built to warn children away from a frozen pond, a microcontroller that animated a puppet for a hospital ward. Her “evil genius” moments had been pranks that left people smiling.
They became collaborators. Mira had a book of her own: yellowed notebooks, handwritten notes, experiments folded into bags. Together they adapted projects from the PDF into appliances of usefulness. They put a humidity sensor in the community garden to save thirsty plants. They made an inexpensive alert for an elderly neighbor’s pills, not to nag but to remind. They taught a group of teenagers how to solder and to read code — their smallest victories were LEDs lit by borrowed confidence.
The PDF stayed with them like a common ancestor, a scaffold of ideas. Elias sometimes flipped to the margins and found new scribbles — different handwriting, different age, a doodle of a tiny robot with an X through it. Each note was a silent conversation between strangers who had once been students of curiosity. The book never became dangerous in their hands; it became a manual for intention. No PC Needed"
On a rainy afternoon, Mira and Elias packaged one of their devices — a weather logger that would text the local garden group whenever frost threatened — and left it on the community noticeboard with a Post-it: “For the garden. Installed by neighbors.” A woman found it the next morning and burst into delighted, incredulous laughter. “Who did this?” she asked the block like an excited jury.
Elias realized then that the true experiment wasn’t the circuits. It was the small, deliberate choice to turn knowledge into something that helped rather than harmed. The PDF could have been a how-to for mischief or menace; instead, it was a ladder. How people climbed it determined the view.
Once, when they were drinking bitter coffee and rewiring an old toy into a talking map, Mira pointed to the title and laughed. “Evil genius,” she said. “What a ridiculous phrase. Genius is often just stubbornness and curiosity, evil or no.”
Elias smiled. The light blinked on his desk, steady as a tiny heart. He thought of the anonymous margin note, “For when you need to say goodbye.” He thought of the woman out of a building two floors down and the neighbors who now checked frost warnings on their phones. He thought of how choices had a geometry — angles that could redirect how a tool was used, how knowledge was a neutral thing that bent toward the hand that held it.
He closed the PDF, saved a copy, and printed one page: the schematic for Project 3, “Blinky.” He left it on the community center bulletin board with a marker beside it and a heading that read, in his hurried handwriting, “Beginner’s Kit — Take One.” A small child found it the next afternoon, eyes wide, and took it home like treasure.
That night, as Elias walked home under a sky the color of solder, the city hummed with a million small circuits of human life: ovens, phones, lamps, radios, the tiny machines of kindness and irritation and necessity. He felt oddly hopeful. Knowledge could be misused, certainly. But he had learned something more precise from the pages of that PDF and the people he’d met because of it: that curiosity, when tied to responsibility and community, could make small, luminous things that outshone any label printed on a cover.
