The circuit control lamp brightness with PWM, and it is good for adjusting incandescent lamp light; also it uses 555 timer as astable multivibrator to control low-power lamp. PWM controls power to lamp and changes brightness easily and this PWM Based Lamp Brightness Controller Circuit runs on 6V battery and works for many lighting needs. […]
555 Timer Projects
Rotating LED Array Circuit using IC 555
The Rotating LED Array Circuit using IC 555 works like an LED flasher and creates a rotating light effect when we arrange the LEDs correctly, hence, this simple project is easy to build and delivers impressive results. Furthermore, we can use this circuit for decoration, emergency light or alert and this circuit gives two IC […]
PWM LED Ramping Circuit (Slow Bright, Slow Fade)
PWM LED Ramping Circuit (Slow Bright, Slow Fade) make LED light go bright slowly and with not sudden ON/OFF, as this circuit is good for signal, decoration and for soft light. Also, it uses 2× IC 555, LM393, 2N7000 MOSFET for smooth change and the circuit works best with 3 to 12V power with 6V […]
Simple 555 Timer Based Animal Repeller Circuit
Simple 555 Timer Based Animal Repeller Circuit is small device to keep animals away, it make high sound which animals do not like and humans mostly do not hear it; also its main part is IC 555 timer which make high frequency sound. Sound is around 15 kHz to 120 kHz (ultrasonic), therefore, this circuit […]
Timer Based Mosquito Repeller Power Saver Circuit
Mosquito repellers are popular to keep bugs away, as they use ultrasonic sound or chemical spray; but if it is always ON then they use much electricity. To solve this problem, we designed a timer-based mosquito repeller power saver circuit, it switches the repeller ON and OFF at fixed intervals to reduce power consumption and […]
Mobile Incoming Call Detector Circuit
Mobile Incoming Call Detector Circuit is a smart project, which detect incoming call and make LED light up. Circuit is good for noisy places where ringtone is hard to hear and can catch RF signal from phone when call comes. In addition, the circuit uses LC circuit, transistor, 555 timer to turn ON LED and […]
