এটা পাবো কোথায়
mine is not working 😭😭 what value resistor to use at the voltage divider
Please refer to the circuit at 00:22~00:26 and 5:40~5:47 in the video. I used a 1.5K resistor for R1 and a 4.7K adjustable resistor for R2. Please check the circuit carefully, the soldering is correct and it can work normally.
Pdf plz
