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 […]

Two-Way Intercom Circuit
This simple Two-Way Intercom Circuit let two places talk to each other like old home or office system; also main parts of this circuit are: Microphone: change voice to electric signal Audio amplifier (LM386): make mic signal strong Speaker: change strong signal back to sound SPDT switch: choose talk or listen mode Battery: give power […]
Long Range IR Transmitter Circuit
Compared to basic circuit this Long Range IR Transmitter Circuit can send IR light farther using easy parts, also its main idea is to make IR LED blink light in pulses. Furthermore, most IR receivers catch specific frequency made by IC 4047. Using more LEDs together or stronger LED gives more IR light, so with […]
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 […]
Simple Footstep Electricity Generator Circuit using Piezo Transducer
To begin with, we use piezoelectric transducers in a footstep power circuit because they convert foot pressure into small electrical power. Furthermore, piezoelectric effect means crystal which makes electricity when press or stress happen and if we press special crystal a small current comes out. Hence, Simple Footstep Electricity Generator Circuit uses parts like piezo […]
Simple Crowbar Circuit
Simple Crowbar Circuit is safety part in electronics, as it protect from high voltage spike or surge; it work like fuse but does not burns and it gets short circuit fast to stop damage. Furthermore, it use SCR or TRIAC for shorting, transistor or Zener to trigger; also trigger watch voltage all time and if […]
