Hot wire foam cutter - Arduino PWM
Last time I did the Hot wire foam cutter but I missed the temperature control. So that's why I made a simple PWM control. The whole project was based on Arduino ATtiny85 Digispark. For this project I only needed three pins, so the ATtiny85 is fine. Also I carried the wires in the PVC pipes.
