In this post halogen lamp draws very high current at switch ON. Cold filament resistance is very low and this causes sudden inrush current. Lamp life becomes short with this circuit protects lamp and it also protects outside fuse and switch indirectly. Soft ON Circuit for 12V Halogen Lamp reduces this problem. Lamp voltage rises […]

Fading LED Circuit using Arduino and Potentiometer
This project shows how to control Fading LED Circuit using Arduino and Potentiometer. Potentiometer gives analog voltage. By rotating the potentiometer knob varies the voltage output and arduino reads this variation. Arduino reads it and changes LED brightness and this LED brightness changes smoothly. It is easy to make a simple project for beginners and […]
Simple Up Down Fading LED Circuit
This circuit makes LED glow slowly and then fade slowly which looks like breathing effect. It uses simple parts like only resistor capacitor and transistor and with no microcontroller. This Simple Up Down Fading LED Circuit is good for beginners and easy to build on breadboard. This type of circuit can be used in shopping […]
Arduino and Joystick LED Controller Circuit
This project shows how to control many LEDs using one joystick and Arduino. The joystick moves in X and Y direction. Arduino reads this movement and turns ON or OFF the LEDs. This Arduino and Joystick LED Controller Circuit is simple to build. Good for beginners and Arduino lovers. Arduino Coding: Coding Explanation: Circuit Working: […]
Simple Push Button Circuit with Arduino
This project show how to make very Simple Push Button Circuit with Arduino. Push button act like an ON and OFF switch. When we press button one time then LED changes its state. First press LED will turn ON. And second press LED will turn OFF. It keeps doing the same. All this happen with […]
