The Mini Infra-Red Remote Robot Controller shield for Arduino Nano is designed to drive mini mobile robots. Low voltage DC Motor controller interface allows Infrared wireless control of two DC motors, two PWM and 2 Direction signal outputs to drive two motors separately. TB6612 IC is the heart of the project. IC can handle constant current up to 1.2A, Supply 6-12V DC. One LDR connected to Analog pin A7 for application like light sensitive robot controller. Infrared receiver TSOP1738 used as IR receiver which is connected to Digital pin D2 of Arduino Nano. Nano D7-Direction Motor A, D4 Direction Motor B, D5 Motor A PWM signal, D6 Motor B PWM signal.
