Developing a system to interface the telephone line with a microcontroller is the main purpose of this project which will involve the of DTMF tones. The device was based on the ATmega8 microcontroller ...

[hw640] has put together a well written and detail packed explanation of how to interface with a digital rotary switch. These digital opto encoders have just two outputs with four possible logic ...

Many microcontroller designs typically mix multiple interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs, performs processing and writes to outputs.

Remote access devices like IP KVMs are usually built around powerful single-board computers such as the Raspberry Pi. But ...
