How does an Arduino control the brightness of LED using a potentiometer? Take a sample of the potentiometer with an A0 pin of the Arduino, which has a resolution of 1024 values (10 bits), and convert the potentiometer output voltage into an integer value between the range of 0 to 1023 vo...
In addition to that, using the right potentiometer we can adjust the controls responsiveness, or reduce the amount of servo travel, and using the left joystick we can sub-trim the rudder or adjust the neutral position of the servo arm. Oh, and I almost forgot the mention, the main feature...
This can be very useful if you want to be able to change resistance on-the-fly from anArduinoor other microcontroller. For example toadjust LED brightness. Potentiometer Wiring Examples The way to wire up a potentiometer depends on how you’re planning to use it. Usually, the middle pin is...
In this tutorial I will show you how I built an Arduino hexapod. As the name suggests, the hexapod has 6 legs but in addition to that, it also has a tail or abdomen, a head, antennas, mandibles and even functional eyes. All of this, makes the hexapod look like an ant, so therefo...

In servos generally a feedback component is a potentiometer, which is directly connected to rotating actuator. The potentiometer acts as voltage divider which is fed to the control electronics. This feedback helps control electronics to determine the amount of power given to the motor. ...
The UART or serial module that is attached to the back of the LCD is responsible for sending and receiving serial communications between the Arduino and the LCD and it has a onboard potentiometer to adjust the brightness of the screen. ...
Arduino based Line Follower Robot A Line Follower Robot (LFR) is one of the most popular Arduino robotics projects that teaches core concepts of automation and sensor integration. This step-by-step guide will show you how to build a professional-grade line follower robot using Arduino UNO, with...
Both motors can be driven simultaneously while set to a different speed and direction and can also power two brushed DC motors or one 4-wire two-phase stepper motor. All driver lines are protected by diodes from back-EMF. So how do you drive a DC motor with an Arduino and a Motor driv...
