Wide range of ARM development boards is currently available on the market. Their complexity spans from the simple 8-bit boards to more powerful ones that are also suitable to use as general purpose computers. The most popular ARM board currently available is without any doubt Raspberry Pi. Several study examples that demonstrate its usage are available on the internet. While the input/output devices available in the basic set are very fundamental, these examples are hard to use in the educational purposes directly.
We have developed our own input/output extension board with the basic components. We additionally implemented HTML and javascript based development environment for Raspberry Pi programming. 9 educational case study examples, which demonstrate the basic tasks, such as buttons and LED module control, and also more complex tasks, such as PWM (Pulse Width Modulation) output control and I2C communication, were written
