@robotbuilder Look in the windows device manager under com ports. You could also look in the Arduino IDE under tools ... ports.
@robotbuilder A virtual com port should show up if you have the arduino software properly installed and When you plug an ESP R or the window board.
@risto Always connect a protection diode across a motor, relay coil, or electro magnet. The diode's cathode connects to the positive power voltage s...
The question is what is the circuit of the driver modules? I'm assuming the common of the control input is connected to the common of the output circu...
@lobster The next question is: do you want to measure music power? If so, then you will need some form of averaging. The next question is how to di...
@lobster Here's a possible RMS circuit, The DC output would connect to an Arduino analog input. But keep In mind it won't be isolated from you...
@will Those AC voltage and AC current sensors appear to be meant for power line frequencies, (50 or 60 Hz) It's unlikely that they will be accurat...
Hi, I can help. A power meter should be flat over the entire frequency range. It only needs to show the product of the AC voltage and AC current at...
