Simple AC Mains Powered LED Night Light Circuit
This tutorial explains a simple AC mains-powered LED night light circuit; the circuit runs directly from a 230V AC mains supply and does not require a large transformer. Furthermore, it can light 24 bright white LEDs with each takes 50mA current and also it is small, cheap and good for night room light. Also, circuit […]
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 […]
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. […]
Automatic Night Lamp Circuit with Photocell
Automatic night lamp use photocell to check light or dark; when dark the lamp is ON and when light the lamp goes OFF. This type of circuit is good for street, garden and security lights and also the parts used in circuits are LDR (ORP12), op-amp (uA741), relay which controls the AC lamp. Also, low […]
