The system is simple but so beautiful that made a pcb design looks very nice also afford a good hard ne555 is divided with different frequencies in different intonation frequency setting resistors does the audio output amplifier with lm386 is raised. Fun is a simple circuit circuit diagram in pdf format, printed circuit board and the settlement plan.

Smart Remote Atmega88 Circuit Copy the two buttons
The only control that are not in the market for copy and discontinued controls over tv, satellite receiver, etc. “smart control” to control such devices sold will be copied to the control as a simple smart control right lar and copying smart control signal mutual buttons to press.
Atmega88p made with one of the most fundamental examples of intelligent control circuitry for the control to follow the situation more clearly understood that the test video. the circuit diagram of the application and have the C codes CodeVision
