This post is about PWM Dimmer Circuit for 12V DC Lamp which controls lamp brightness and saves energy, also main part of this circuit is IC 555 timer chip which make PWM signal. Furthermore, PWM signal change power to lamp by duty cycle and IC 555 timer works like astable multivibrator at 2.8KHz which is […]
Light Controlled Switch Circuit using IC LM311 and LDR
This article talks about Light Controlled Switch Circuit using IC LM311 and LDR, as it simple and very useful and it feel light change near it. We find this circuit in many place like automatic light, street lamp and security system and main thing is about voltage comparator with LM311 IC. Then LDR sees light […]
IC 555 Timer Based Mini Flasher Circuit
IC 555 Timer Based Mini Flasher Circuit makes LED blink light with a set speed, as this circuit often uses for signal, indicator and hobby projects. Also, IC 555 timer work in astable mode to give pulses all the time and if required we can change blink speed with a potentiometer, in addition the circuit […]
Simple Micro Flasher Circuit using IC CD 4093
Simple Micro Flasher Circuit using IC CD 4093 is easy way to make LED blink for many indicators, also CD 4093 has four NAND Schmitt trigger gates inside. In addition, circuit runs on 6V battery and need few parts only which is very simple and good and its flashing happens because one NAND gate turn […]
Simple Dark Sensor Circuit with Buzzer
The Simple Dark Sensor Circuit with Buzzer is an easy project to build because it detects the absence of light and activates a buzzer, moreover, users can apply it in night lights, security systems and alarm circuits. Here, circuit works with LDR, 555 timer and buzzer, as low light makes buzzer ON. Furthermore, this circuit […]
PWM Based Lamp Brightness Controller Circuit
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. […]
