General Info

Our son (1 year old) loves to click and press tactile things, so this box was made to house an arcade button and simply increment a counter every time it is pressed. The total count is stored in EEPROM for data persistence and is displayed on a small OLED panel using an attiny85.

Theo presses button, counter goes up and inverts colors, everyone is happy.

Technologies

- Fusion 360

- Arduino

Setup

Print the box and wire the attiny85 to an 18650 for power and to a 32x128 OLED for the output, reference the Arduino code for pin definitions.

This is a very simple bit of code so feel free to modify as needed or desired.

Usage

Power on the device and start clicking!

Notes

Occasionally the count is not stored reliably, I suspect this is due to my relative inexperience with EEPROM.
