cehic1994's video: Arduino Voltmeter and ACS712 5A Current Sensor with MAX7219 Dot Matrix Display

In this video I have made test of voltage and current sensor for arduino. I have made simple arduino Voltmeter and Ammeter. I'm not very satisfied with result's but I have explained why results is not so accurate. In this video I'm using this components: - Arduino Uno(ch340) - Voltage sensor up to 25V - MAX7219 Dot Matrix Module Display - ACS712 5A 5V Current Sensor Module - Breadboard, wires, batteries, bulbs...
