an Arduino Nano Ouija Board
Mystical Ouija Board User Manual
Overview
An electronic Ouija board that uses capacitive/resistance touch sensors to move a planchette across a digital board displayed on an OLED screen. Theory is that a spirit or entity may communicate through this electronic devise by manipulating the human body.
For Entertainment Purposes Only! Use with Caution!
Hardware Requirements Arduino Nano 128x64 OLED Display (SSD1306, I2C) 4 Touch Sensors connected to analog pins A0-A3 I2C Connections: SDA/SCL to display
Wiring Touch Sensors: Connect to A0, A1, A2, A3 OLED Display: Connect via I2C (typically A4=SDA, A5=SCL) Power: 5V and GND to all components
How It Works Touch Detection: Monitors capacitance/resistance changes on 4 sensors Sensitivity: Threshold set to 5 for responsive movement Planchette: Appears as a transparent ring on the board
Usage Instructions
- Power On: Upload sketch and power the Arduino
- Touch Sensors: Lightly touch any of the 4 sensors
- Watch Movement: Planchette moves based on touch intensity
- Serial Monitor: View debug info at 9600 baud for troubleshooting
Troubleshooting No Movement: Check sensor connections and threshold value Too Sensitive: Increase threshold value (line 101) Display Issues: Verify I2C address is 0x3C
Customization Adjust movementDivisor (line 112) for movement speed Modify threshold (line 101) for sensitivity Change minMovement (line 113) for minimum motion
