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 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 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...
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 complete code explanations and tr...
Daniele’s BrachioGraph is a self-described “cheapest, simplest possible pen plotter.” Seeing as how there’s little more to this drawing robot other than a Raspberry Pi Zero, three micro servos, a USB cable, a pen, a few bits of wire and … just … stuff? (Some of their ...

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. ...
Many advanced options require hardware support to work. So, by default, they are set to -1, which means ignore.Specify Servo ResolutionBy default, the software will have a servo resolution of 180 positions. While most hobby servo controllers (i.e., Arduino, EZ-Robot EZB) are limited to ...
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...
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. ...
