The function EEPROM.read() is used to read a particular data byte from the internal EEPROM of the Arduino’s microcontroller. The function has a single parameter which is the address from which the data should be read from. The function has a return value which is the actual data byte whi...
In the void loop() function, read the value from the analog pin connected to the potentiometer. This value is between 0 and 1023. 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 resol...
Variable resistors and potentiometers each augment the standard resistor symbol with an arrow. The variable resistor remains a two-terminal device, so the arrow is just laid diagonally across the middle. A potentiometer is a three-terminal device, so the arrow becomes the third terminal (the wipe...
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...
In this tutorial I will show you how I built an Arduino based hexapod. As the name suggests, the hexapod has 6 legs but in addition to that, it also has...
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. ...
Electronic devices you build with Arduino start to become very cool when you connect them to the network.Let’s see how to connect an Arduino to a WiFi network.The Arduino must have WiFi connectivity, for example the Arduino MKR WiFi 1010, which is the one I use, or the Arduino Uno ...
Speed Control System: Add a potentiometer or switches to adjust speed of DC motor using Arduino. This is particularly useful when testing your robot on different courses. You can implement multiple speed modes for straight lines versus turns. LCD Display Integration: Add a 16x2 LCD with Arduino...

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 ...
