Today I finished the project, which I started a few months ago. Three channel desktop power supply with the adjustable output voltage. In the future, I would like to add control of the current limit, but I will talk about it on another occasion.

I recently built a 1kHz sine waveform generator, the device works great, has adjustable amplitude and is suitable for testing audio amplifiers and for repairing them. So I thought it would be nice if I could install a small panel voltmeter to display the output voltage.

This is my new Arduino project, a two-channel voltmeter with a thermometer.
This device uses Arduino's 10-bit analog-to-digital converter, software oversampled to 12-bit and every four measurements are added to the average value. This measured value is printed on the display every 300 milliseconds.
