In this video, we will make a testcharging device for batteries in Arduino. Scheme and sketch turned out not small, but there are so many functions! The device can not only charge the batteries, but also test their capacity, measure the internal resistance of the battery, charge two batteries connected in series and store settings for 4 types of batteries, etc.
The entire process of the device is displayed on the graphic display 128 * 64.
