A line following Arduino sketch for the AppShed AppCar
- Laptop/Computer running Windows or Mac
- NodeMCU 1.0 (ESP-12E Module)
- Motor Shield
- Infra Red Sensors x 2
- 2 Motors with Wheels (The basic AppCar Kit)
- Arduino IDE 1.8.X
- NodeMCU Drivers for Windows & Mac (http://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers)
- Visual Studio Code (with Arduino IDE plugin - for Intellisence Code Editing)
We make use of only 2 IR sensors for this project mounted against a metal plate. It is important to use a white floor surface with black electric tape.
- Height between floor surface and IR LEDs = 5mm
- Width of Electric Tape on the floor = 20-25mm
- Width between IR Sensors = 20mm
