Sounds like a fun challenge, but you’ll need a clear plan first. Pick a core function—say, a small servo‑driven arm—then add a watchdog that purposely resets it at random intervals. The glitches will be predictable enough to keep the machine alive but chaotic enough to look interesting. Just remember to keep the safety interlocks in place; you don’t want a glitch turning into a fire.

#include <avr/wdt.h> #include <Servo.h> Servo armServo; int servoPin = 9; // Digital pin for servo int glitchInterval = 2000; // milliseconds between glitches void setup() { Serial.begin(9600); armServo.attach(servoPin); armServo.write(90); // Start in the middle // Enable watchdog with 2 second timeout wdt_enable(WDTO_2S); // Disable external interrupts that might interfere cli(); } void loop() { // Normal operation: rotate arm back and forth for (int pos = 0; pos <= 180; pos += 10) { armServo.write(pos); delay(100); } for (int pos = 180; pos >= 0; pos -= 10) { armServo.write(pos); delay(100); } // Random glitch: reset watchdog to trigger a reset if (random(0, 10) < 2) { // 20% chance each cycle Serial.println("Glitch triggered – resetting!"); // The watchdog will reset the MCU after 2s // Let the main loop finish, then reset wdt_reset(); // Reset watchdog counter so we don't reset immediately delay(glitchInterval); // Let the watchdog count down } // Normal operation continues after reset wdt_reset(); // Prevent reset during normal operation delay(500); // Short pause before next cycle }
