Arduino Based Control LED Light Circuit with Potentiometer
Want to make an LED glow bright or dim just by turning a knob? then this simple Arduino Based Control LED Light Circuit with Potentiometer does that same thing. Turn the knob to adjust the LED light from soft to full brightness, also it is a fun and easy way to learn how Arduino reads […]
Push Button LED Circuit using Arduino
This simple Push Button LED Circuit using Arduino shows how to turn an LED ON and OFF using a push button switch. When we press the button, the LED turns ON, and when you release it, the LED turns OFF; furthermore, this project helps beginners learn about digital input and output in Arduino. Arduino Coding: […]
Arduino Based Smart Traffic Light Circuit for Beginners
Traffic light is one of the best beginner Arduino projects, which shows how to control LEDs using Arduino; also this project works like a real traffic signal like red for stop, yellow for wait and green for go. In addition, Arduino Based Smart Traffic Light Circuit for Beginners is easy to build and fun to […]
Solar Tracker Circuit using LDR and Op-Amp
Solar panels gives more power when they face the sun directly, also manual turning is hard and wastes time; automatic solar tracker moves panel automatically with sun. This Solar Tracker Circuit using LDR and Op-Amp uses simple parts and with no Arduino or microcontroller; its main parts are two LDR sensors, TDA2822 IC, few resistors, […]
Electronic Eye Circuit using IC 4049
This project is for small Electronic Eye Circuit using IC 4049, which can sense darkness or shadow. When light falls on the LDR, the circuit remains OFF and when an object blocks the light, the LED and buzzer turns ON; moreover, this circuit also works like a magic eye and is useful for security systems […]
