The purpose of this project is to build a device that can capture the Infrared (IR) signal transmitted by all types of remote controls. It can capture IR codification signal at the modulation frequency level. This device not only simply captures IR signal, it also can decode this IR signal. Telling us what codification is […]
If you want to build simple function generator then this circuit is for you. This function generator is built based on IC XR-2206. It can be used to generate Square, TTL, Sine and Triangle waveforms. The frequency range is from 1Hz to 1Mhz and adjustable via VR3. User can change output voltage using VR2.
