![]() ![]() Int potentiometer = A0 // initialize the A0analog pin for potentiometer ![]() Servo servo_control //initialize a servo object for the connected servo Inside the Loop Function, we read the analog value of the Potentiometer and map it to 0-179 (i.e 180 values corresponding to 180 degrees).The mapped values are then used to turn the servo motor.Therefore as we turn the Potentiometer Knob, the shaft of the servo motor Turns. On the yellow color terminal, we provide a PWM signal which controls the. In the first, we include the Servo Library to control servo.Then we create an Object named servo_control, initialize angle variable with 0 and declare Potentiometer Output Pin A0.In the setup function, we specify the servo signal pin i.e 9 in our case. val map (val, 0, 1023, 0, 179) The last 2, 0 and 179, set the range of values sent to the servo to be between 0 degrees and 179 degrees. The connections for servo motors with Arduino are as follows: Connect the black wire on both the servo motors with the GND on the Arduino Connect the red wire. Arduino UNO (Link to store) Servo motor 4.8V - 6V (Link to store) Jumper wires. We can control the servo motor by connecting the Vcc pin to 5V and GND pin to 0V. CONSEW CSM1001 Servo Motor Instruction Manual. ![]() Servo motors have a built in feedback circuitry which helps to find the position of servo axis, this gives accurate movements of the axis.Servos can be used to control movements of robots like arms, legs or to rotate objects e.g Spider Bot where Arduino control servo motor for the leg movements of a spider.Servo motor requires PWM signal i.e Pulse width Modulation Signal for controlling the position of the shaft so we need to use one of the PWM pins of the Arduino.PWM pins are marked by a ‘~’ character.Here we are going to use the D9 pin of Arduino UNO.So let’s start.ĭ9 << Servo Signal Pin (Yellow/White wire) The CSM3001 is a 1 HP (750 Watt) Brushless Servo Motor that includes the Needle Positioner (synchronizer) Energy Efficient - Saves up to 70 Electricity. In this article, we will control servo motor angle using Potentiometer with Arduino UNO. ![]()
