Arduino Current Control

Arduino Current Control In this video we use an Arduino Nano, an INA219 current monitor, an OLED, a potentiometer, and a relay to control the current of an external DC load. We use the potentiometer to set the maximum current up 3.2A (the max the INA219 can handle) The INA219 will monitor the current and send the results to the Nano. If the Arduino detects the current is greater than the selected current, it will trigger the relay and cut off the load. This is written as a single shot. The only way to reset the load is to reset the Nano. Devices used in this example include: Arduino Nano clone https://www.amazon.com/Gikfun-ATmega3...
