Simple MIC Amplifier Circuit using IC LM358
Microphones detect sound, but they produce a very weak signal; then this Simple MIC Amplifier Circuit using IC LM358 make signal strong. Also, LM358 chip is cheap, easy and can work with two mic signals so people use it a lot. Audio amplifiers take weak sound signals from mic or music player and make them […]
How to Build a Mini Tesla Coil Circuit
In this post for How to Build a Mini Tesla Coil Circuit these tesla coil make high voltage and low current. Furthermore, mini tesla coil is small version of big one and it can light small things or make tiny sparks and also it runs on 9V battery or other low power. Circuit Working: Parts […]
H-Bridge PWM Driver Circuit using IC 555
This H-Bridge PWM Driver Circuit uses an IC 555 to control the speed and direction of a DC motor; also the circuit operates without driver transistors. Furthermore, motor connect direct to two IC 555 and moreover, motor speed and direction can also be change; so we can only use two IC 555 to control the […]
Simple Fade On Fade Off LED Circuit
This Simple Fade On Fade Off LED Circuit makes the LED turn ON and OFF gradually instead of suddenly; also the circuit creates a dimming effect with smooth transitions that look pleasant to the eye.
