Counter Mk1 Prototype

 I just finished building this prototype during my free time in class. For now, it's just a STM32F103C8T6 development board connected to a breadboard with an I2C screen, a power supply, and some buttons. You can increment, decrement, or reset the counter using the three buttons, and the small screen will display the current count. 

I intend to make this into a finished project with an ergonomic 3D-printed case and some bigger buttons. Its purpose is to help with counting something, while being easily held in an unoccupied hand.
