TinyGo PONG clock

PONG clock

Show the time while playing a game of PONG.

Youtube video.

This clock should not be used for time-sensitive tasks as it might run a couple of seconds late to adjust the time change to the game.

Bill of Materials

• BBC micro:bit (you could use a adafruit itsybitsy m0 or any other microcontroller compatible with tinygo)
• sensor:bit expansion board for BBC micro:bit
• RTC DS3231
• HUB75 64x32 RGB LED matrix
• dupont female headers, wires and solder

Circuit and connections

Connect the RTC DS3231 to the I²C interface (bottom right corner of the sensor:bit expansion board). The rest of the pins as described in the microbit_connections.md file or the following image, be aware there are some connections between the two connectors of the RGB matrix and between the left one and the microbit expansion board:

3D printed cover

I made a simple 3D printed cover. There are 3 tabs pre-cut to pass the power cable if needed, two at the sides and one at the bottom. There's also three holes for screw hooks on top.
