The transmitter requires a Pyboard 1.x (not Lite), a Pyboard D or an ESP32. Output is via an IR LED which needs a simple circuit to provide sufficient current. Typically these need 50-100mA of drive ...

This is the complete circuit diagram for this home automation project. I have explained the circuit in the tutorial video. The circuit is very simple, I have used the GPIO pins D23, D22, D21, D19, D18 ...

Unfortunately, the Shield only has an IR receiver, no transmitter. So I have to build my own transmitter. With the motto "Simple and Dirty", a plug-in IR transmitter module with driver function is ...

I chose Bluetooth for communication between the phone and the IR transmitter hardware, because of its low power and low latency, when compared with Wi-Fi. I was looking for a commercially available ...
