Hartley Oscillator In simple terms, the oscillator is a circuit which converts DC power from the supply source to the AC power to the Load. Oscillator system is built using both active and passive components and it is used for the production of sinusoidal or any other repetitive waveforms at the output without any application of an external input signal. We discussed few oscillators in our… |

Wireless Switch Circuit using LDR and CD4017 Have you ever feel a shock by touching the switch? It does not generally happen but sometimes physical contact with switches may be dangerous. But what if the switch gets wireless and you don’t have to press any button at all for switching on or off your home appliances. So today we are building a Simple Wireless Switch Circuit in which there is no need of physical contact… |
