Arduino: Photoresistor and Servo motor working together to indicate light

This fun project is to visually and mechanically indicate day/night or light/dimness around with the help of a photoresistor that reads the light values. And that’s connected to a motor (a servo) which has an arm/arrow connected to it and it moves to certain positions depending on the light sensed by the photoresistor. Lastly, the […]

Arduino: Building a music tempo controller with simple components

In this project, I built a simple system where we can play a tune/music through a speaker (sound/tone is of our choice) and while it’s playing, we can control the tempo in real time. For the speaker, I used an inexpensive passive buzzer hooked up to a 10K resistance potentiometer. I insert a turning knob […]
