In this circuit, all you need is to pass your hand above LDR to ON or OFF the switch. Wireless Switch Circuit using CD4027: This is a simple circuit which needs no physical contact with the appliance.Here, the input voltage should be DC voltage to get the accurate output on LCD. This circuit measures the input voltage from 0V to 5V. Digital Voltmeter using 8051 Microcontroller: This is a simple digital voltmeter circuit designed using 8051 microcontroller.It may be used as emergency light and also as a reading lamp. LED Lamp Circuit using USB Port: This is a simple USB LED Light circuit which produces an output of 5v.This article describes the circuit of FM radio circuit. FM Radio Circuit: FM Radio circuit is the simple circuit that can be tuned to the required frequency locally.So by using this circuit, we can increase the lifetime of battery. You can use this circuit to check car battery or inverter. Battery Level Indicator: This article explains you how design battery level indicator.Simple 100W Inverter Circuit: This is a small Inverter circuit which converts the direct current (DC) to alternating current (AC).This circuit may be used as wireless power transfer circuit, wireless mobile charger circuit, wireless battery charger circuit, etc. Wireless Mobile Battery Charger Circuit: This circuit mainly works on the principle of mutual inductance.The operating voltage of these ICs is from 2V to 6.6V DC. This pair of encoder and decoder ICs establishes the communication with high level security.
