An entertaining small electronic project that produces sound according to the quantity of light it senses, is the light dependent screamer circuit. A light dependent resistor LDR or resistor that adjusts its resistance in response to light intensity is used in this circuit. All in all, the circuit functions as a little ‘screamer’ that increases […]

Simple Intercom Circuit
This intercom circuit is like a fancy walkie talkie for inside a household of a building . Instead of buttons it uses electronics to let you talk hands free. You speak into a microphone, which changes your voice into electrical signals. These signals are made stronger by an amplifier circuit. A clever part of the […]
Simple Walkie Talkie Circuit
This is a basic walkie talkie circuit. It uses low power to let two people chat over a short distance, kind of like two tin cans connected by string. But unlike fancy walkie talkies, you can only talk one at a time on this circuit. Circuit Working: Parts List: Category Component Quantity Details Resistors 10k […]
Simple Electronic Drums Simulator Circuit
If you want to play drums but do not have a whole kit. This circuit is like a mini electronic drum set. It uses clever parts to create sounds that mimic real drums like a kick or a snare. These sounds are made with electronic tones instead of drum parts. There are different ways to […]
Simple “Hee Haw” Siren Circuit
This special electronic circuit makes a sound like a siren, but instead of a steady wail, it goes high low high low in a repeating pattern kind of like saying “Hee Haw.” It is like a fun siren sound you might hear on a cartoon! Circuit Working: Parts List: Component Type Description Quantity Resistors(All resistors […]
