Summary of ATMEL ATTINY45 BLUETOOTH SCOREBOARD CIRCUIT
This project creates a VGA scoreboard remotely controlled via Bluetooth using an ATtiny45 microcontroller. An Android device sends commands through a BTM400-6B module, which the microcontroller reads to update scores on a monitor. The system operates as one-way communication from the phone to the board. All source code, schematics, and firmware are open-source.
Parts used in the Bluetooth Scoreboard:
- Atmel ATtiny45 microcontroller
- BTM400-6B Bluetooth module
- VGA monitor
- Android device (cellphone or tablet)

Bluetooth Scoreboard
This project aims to display a scoreboard in a regular VGA monitor, remotely controlled with an Android device (cellphone, tablet) via Bluetooth. Bluetooth module BTM400-6B will wait for a connection from a device (e.g. an Android phone) and will act as an 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.
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.
