Infrared (IR) Intruder Alarm Circuit
This article tell how to make new type of Infrared (IR) Intruder Alarm Circuit, where it can find person who walk through invisible light beam. Circuit have two main part: one transmitter and other one is receiver. Transmitter send out one infrared light beam across a room and if someone goes in front of light […]
LED Chaser Circuit using IC 4017
This LED Chaser Circuit using IC 4017 project make LED lights turn ON one by one like chasing, also it is fun way to learn electronics. In addition, one chip of IC 555 makes pulse again and again and that pulse connects to other chip IC 4017 and it turn ON and OFF each pin […]
Adjustable DC Motor Speed Controller Circuit
To begin with, Adjustable DC Motor Speed Controller Circuit with Reverse Forward Facility discusses about how to make one simple circuit to control DC motor speed and direction, it uses one popular chip called IC 555 and one special switch. Hence, we can change motor speed by turning one knob which controls power and send […]
Wireless LED Light Circuit
Nowadays, there are wireless charging inside many things like phone and even big medical machines. So, in this article we will show how to make Wireless LED Light Circuit which light using one small chip called IC 555, also no wire needed, the LED will light up to show how wireless charging works. What is […]
Red Blue Police Light Flasher Circuit
This article show how to make a Red Blue Police Light Flasher Circuit, as this circuit uses two IC 555 chips which are very common and each chip run at different speed. Hence, they connect to two LED groups in special way, in like opposite direction and this make LEDs blink one after other and […]
