Make a Porch Light That Turns On at Dusk
Build a dusk light in Mokxi with a photoresistor sensor and an Arduino Uno, and use hysteresis so the lamp does not flicker as the light fades.
Build a Talking Skull with a Servo Jaw and Glowing Eyes
Build a Halloween talking skull on an Arduino Uno in Mokxi: a servo jaw timed to a DFPlayer track, green LED eyes and a motion sensor to wake it.
Trigger a Fog Machine with a PIR Sensor and Relay
Build a Halloween motion trigger on an Arduino Uno: a PIR sensor fires a relay for a short burst, then ready and cooldown LEDs show when it can fire again.
Build a Grabbing Candy Bowl with an Ultrasonic Sensor
Build a Halloween candy bowl in Mokxi that grabs back: an HC-SR04 spots a hand, a servo swings down, a piezo shrieks, and a cooldown resets it.
Make a Haunted Window with NeoPixels and a Knob
Build a Halloween haunted window on an Arduino Uno: a NeoPixel strip throws lightning, four LEDs flicker like candles and a knob sets the storm.
Arduino Halloween Props: Build and Test a Jump-Scare Box in Your Browser
Build an Arduino Halloween jump-scare box in your browser first. The wiring, the real sketch walked through line by line, and what to tune before October 31.
