The Scoreboard project is now finished and working!
The idea of this project is pretty simple: control a ping-pong electronic scoreboard from an Android bluetooth-enabled device.
To do this, I used an ATtiny45 which main function is to display the current scores in a VGA monitor while reading from a bluetooth module UART interface waiting for “commands” that will tell it what to display. The Android device sends the commands via bluetooth, running an application specially designed for this project.
As usual, the whole project is open source, including schematics, AVR firmware and the Android application.

In this post, you will find how the Bluetooth module interacts with the ATtiny45 in the VGA Scoreboard project.
The Bluetooth module will wait for a connection from a device (e.g. an Android phone) and will act as an SPP (Serial Port Profile) re-passing everything received from the device to the UART interface. In our case the ATtiny will read the data but won’t “speak back” to the module, so it’s really a one way communication from that point of view.

As it was suggested by Hackaday’s guys, I’ve added a simple push button in the only available pin of my ATtiny45 in order to control the Tiny Pong VGA. The switch toggles the paddle direction up and down, every time you release it.
I’ve made some little changes in the code, so check it out, you might find something interesting or useful. As always, source code, schematics, etc. freely available for download.

I’m still waiting for my cheap Bluetooth module from China which will serve as an input interface for my scoreboard project. In the meantime, I’ll show you how to convert your ATtiny microcontroller into a Pong game (with no input so far).

This project aims to display a scoreboard in a regular VGA monitor, remotely controlled with an Android device (cellphone, tablet) via Bluetooth.
