To begin with, Power ON Delay Circuit using IC 555 give time gap between power ON and circuit starts. When trigger comes, IC 555 work in monostable mode and give one output pulse for set time; furthermore, resistor R1 and capacitor C2 make timing part for delay. When the circuit is OFF, the output stays […]

Panic Alarm Button Circuit using IC 555
Make cheap and easy Panic Alarm Button Circuit using IC 555, as this IC 555 work like bistable circuit with two states: alarm ON and alarm OFF. Pressing the panic button starts the timer, which stays ON until we press the reset button; the timer produces a HIGH output, turns ON the transistor, and activates […]
Frequency Divider Circuit
To begin with, a Frequency Divider Circuit take signal with high frequency and give signal with lower frequency, also it changes the signal in way to reduce frequency. Two common ICs used for this: IC 4017 Decade Counter: IC 555 Timer: Circuit Working: Parts List: Components Values Quantity Resistors (All resistors are 1/4 watt unless […]
Thyristor Switching using Snubber Circuit
In this article, we discuss Thyristor Switching using Snubber Circuit, a thyristor acts as a switch in power electronics applications that handle high voltage and high current. Thyristor also called SCR (Silicon Controlled Rectifier) which turns ON by gate signal and to turn it OFF the current must stop; but when turning ON and OFF […]
Basic Circuit for Multi-Way Lamp Switching
We can control one bulb from many places using Basic Circuit for Multi-Way Lamp Switching. People also refer to three-way switches as two-way switches and they refer to four-way switches as intermediate switches; also they commonly use both types in multi-way switching systems. Firstly, three-way switches go at both ends like at hallway doors and […]
How To Test a Multi-Core Wire using Cable Tester Circuit
We can learn How To Test a Multi-Core Wire using Cable Tester Circuit through this tutorial, also this tool check if cable is working or not. Also, it helps find wrong connection like short or broken wire. This circuit works well for testing multi-core cables that contain several wires, also it helps check whether all […]
