The initial LDC205 board died. So I remade it using an ATTiny85 chip: same function, smaller, cheaper.
- To compile the tinyldc85 code the ATTinyCore repository should be added to the Arduino IDE.
- To upload the sketch an Arduino UNO must be repurposed as a Arduino ISP.
NOTE: If you have problems with the ADC or the serial (e.g. Syntax Error:) update to the newest sketch, and change to 9600 BaudRate.
