To build small devices is fun. This is why I built a 1.5V battery tester using an Attiny and a cheap SSD1306 OLED display from heltec.
The device measures automatically batteries with and without load (with a MOSFET).
I found a small Arduino OLED library and adapted it to work with the TinyWireM library for I2C communication.
