A potentiometer is a device that allows you to change the value of a resistance by turning a knob. In this tutorial you will learn how to use a potentiometer to control the brightness of an LED. Read More 2.6 How to use the Infrared line sensor An infrared line sensor is a simple ...
1 or more dogs (these are imperative for quality control and testing purposes! Cats can be used as a substitute in a pinch but results cannot be guaranteed) Electronics: 1 Arduino board (any arduno board will work i used an older Duemilanove ) 1 Standard servo 1 potentiometer (any valued...
In summary, in this article, you learned how to use the LED PWM controller of the ESP32 with the Arduino IDE to dim an LED. The concepts learned can be used to control other outputs with PWM by setting the right properties to the signal....
Arduino Lesson 15: This is a Super Cool project that turns the RGB LED to whatever color that is put in front of a color sensor. It works for an amazing array of color cards. Arduino Lesson 16: Control the position of a servo from a potentiometer using the Arduino. ...
