IR to RF Converter Circuit
http://circuitdigest.com –
But IR remote has some limitations like low range and it only works in Line of Sight etc. So these limitations can be overcome by converting the IR signal into RF signal. RF signal does not required line of sight and have much better and long range then IR remote.

LED VU Meter Circuit
http://circuitdigest.com –
We have built a Volume Meter or VU meter, with the help of MIC, OP-AMP and LM3914, which glows the LEDs as per strength of the sound, if sound is low, lesser LEDs will glow, and if sound is High more LEDs will glow, check the Video at the end. VU meter also serves as a volume measurement device.

Emergency Light Circuit
http://circuitdigest.com –
Emergency light is an integral part of household electronics nowadays. We all know Emergency light is used during the power failure to light up the home. As it is used during the power failure, it should last long, hence generally bright white LEDs are used in emergency light, because they produce more light and consume less power.
