Using digitalWrite(); function LED turns to OFF. If analogWrite(); value is 0, brightness of the LED is minimum. Conclusion In this article, you have learned about the basics of a Potentiometer and how to use a Potentiometer with an Arduino Uno board to control the LED brightness. I hope...
Now we will use the Servo library, this library is available in your Arduino IDE when you download for the first time. Following the picture below and then using the diagram above with the library code. Above are two examples about control servo by software. Now we will combine hardware(Po...
I made one more example for this tutorial, where I control the speed of the motor using a potentiometer. Here’s the source code of that example: /* Simple Stepper Motor Control Exaple Code * * by Dejan Nedelkovski, www.HowToMechatronics.com * */// Defines pins numbersconstintstepPin...
I wanted to control my drone from an Arduino because I wanted to take a step into the automation of my drone. There was the option of building a drone and using the Arduino as the Flight Controller, but then I would miss out on all of the advanced features that the more popular firmwa...
I'm going to show you how to emulate an Xbox controller with an Arduino, using a USB capable microcontroller and the ArduinoXInput library.
{//and initialize we shall, starting with the Arduino Variable. //we are only using one arduino, so we can use Arduino.global to grab it. arduino = Arduino.global; arduino.Setup(ConfigurePins); } voidConfigurePins() { //configure the Arduino pin to be analog for our potentiometer ...
Before connecting the Arduino with the stepper motor it’s important to set thecurrent limitof the motor driver lower than the stepper motor current rating, otherwise the motor will heat up. A small potentiometer present on A4988 driver can set current limit, as shown in image. On clockwise ...

R2 is a potentiometer that is used to control the sound volume.C2 is a capacitor that sets the voltage gain of the LM386 amplifier. Therefore, the voltage out is 200 times the voltage in. This provides us with the maximum gain that the LM386 can provide.C3...
In this project, we will build a dual digital potentiometer circuit so it can be controlled by a microcontroller such as the arduino. With a dual potentiometer chip, we have 2 potentiometers which can be used to control 2 output devices.
