Sometimes when our circuit power is ON a big current comes suddenly and this sudden current can damage parts like IC, capacitor and transistor; so to stop this we make Slow Voltage Rise Power Supply Circuit. This circuit gives voltage slowly but not full at once, so circuit become safe and work is quite reliable. […]
LDR Based Aircraft Warning Signal Light Circuit
Tall buildings, towers and other high structures require warning lights to ensure aircraft safety and a red 230V LED bulb typically serves as the warning lamp. This LDR Based Aircraft Warning Signal Light Circuit automatically switches ON the bulb in night and switch OFF in day, also it uses LDR sensor, relay and small power […]
Low Power Led Flasher Circuit using Nand Gate IC
Make your led blink easy with this easy to make Low Power Led Flasher Circuit using Nand Gate IC, as it uses IC CD 4093, a quad Nand gate with Schmitt trigger input. Also, the circuit makes led blink with very less power and it can run from small 6V battery too. Circuit Working: Parts […]
Two Star Flasher Circuit with 555 IC
This simple article is for Two Star Flasher Circuit with 555 IC and its main part is 555 timer IC which works in astable mode; also in this mode IC give continuous square wave pulses. These pulses make the two lamps blink alternately, creating a star-like flashing effect; also the resistor and capacitor values show […]
Automatic Light Control Switch Circuit using IC 555
To begin with, this article is for Automatic Light Control Switch Circuit using IC 555, it works with light dependent resistor (LDR). When light falls on the LDR, its resistance changes, the 555 IC converts this resistance change into a switching signal and drives the relay; the relay can then control a lamp, fan, motor, […]
Ultrasonic Blind Stick Circuit using Arduino
Blind people have big problem on road because they cannot see object in front; so to solve this we made an Ultrasonic Blind Stick Circuit using Arduino The stick actively senses objects and uses a buzzer to warn a blind person with sound. We can build this low cost project easily using components such as […]
