Day 3 - DC VA Monitor

Over the past few weeks, I’ve been designing this module. I was initially inspired by similar modules widely available in online stores, and then I decided to create my own version. I believe that the design would be more compact if you used a microcontroller, but instead I use the ICL7017 ADC. This IC converts analog signals into digital values that are displayed on a 3.5-digit LED display. This design is capable of measuring voltages and currents up to 100 volts and 20 amperes DC. However, we can easily adjust the maximum measurement limits as long as they remain within the ICL7107’s full-scale input.
