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.

Transformerless Power Supply Circuit

http://circuitdigest.com

We can convert the High voltage AC into Low voltage DC without using the Transformer. This is known as Transformerless power supply. The main component of a Transformerless power supply is Voltage dropping capacitor or X-rated capacitor, which are specially designed for AC mains. This X rated capacitor is connected in series of Phase line of AC, to drop the voltage.

Voltage Doubler Circuit

http://circuitdigest.com

Voltage doubler is the circuit where we get the twice of the input voltage, like if we supply 5v voltage, we will get 10 volt at the output. Generally transformers are there to step-up or step-down the voltage, but sometimes transformers are not feasible because of their size and cost. So here is the quick, easy and practical solution to double the voltage, using 555 timer IC.
