Another example for the OpenM128 AVR development board here, we will look at the onboard buttons and LEDs again. As stated in a previous article the development board has 8.
In this example we simply flashed the LEDs on a Waveshare OpenM128 AVR development board - I am trying to test out and use a variety of AVR related boards that I have, this is a very nice compact development board with LEDs, buttons, joystick...
In this example we connect a piezo buzzer to PB0 of our Attiny13a. We use mikroC pro for AVR which has a built in sound library to play a tone.
