The “Hee Haw” Siren Circuit is a fun sound project that makes a high and low noise like “Hee Haw” instead of one long sound. Also, simple electronic components such as resistors, capacitors, transistors and sometimes ICs make up the circuit. The pitch of the sound goes up and down again and again and we […]
How to Convert a Speaker into a MIC Circuit
This article for How to Convert a Speaker into a MIC Circuit shows how to turn a speaker into a microphone, as it uses the speaker to catch sound and the sound turns into a weak signal. Furthermore, this transistor circuit makes the signal stronger, but the mic wont be very clear but it is […]
Fog Horn Circuit
Ever wondered how fog horns make that deep, spooky sound? In the same way, this Fog Horn Circuit is a small sound-making device that uses electronics to produce the low, rising and falling fog horn noise. Moreover, people use these circuits for fun projects as well as for learning electronics. Circuit Working: Parts List: Components […]
Hand Grip Strength Tester Circuit
Do anyone want to test their grip strength? Like small hand wrestling with ourselves? So this Hand Grip Strength Tester Circuit is a hand grip tester, it uses simple electronic parts to check how hard we can squeeze; more squeeze then more lights turn ON which shows our grip power. Circuit Working: Parts List: Components […]
Simple Guitar Fuzz Circuit
Imagine we play guitar but we want loud, fuzzy, buzzing sound which is not clear; so a Simple Guitar Fuzz Circuit is like small monster in a box. It changes our normal sound and makes it fuzzy, noisy or roaring; rock and blues players use this as it comes in small box with buttons we […]
How to use an LED as a Light Detector Circuit
LEDs mostly make light but they can also sense light! Like a secret power, when light hits an LED in the right way, it generates a small amount of electricity; scientists call this phenomenon the photovoltaic effect, which works like a tiny solar panel. In this post for How to use an LED as a […]
