Now let’s switch to the Arduino IDE to write the program. Connect the brown wire to 0V, the red one to 5V, the orange one to the pin 9: Upload the Tilt Sensor Sketch With the Tilt Sensing Servo Motor Controller circuit built on the fullsize clear breadboard, it's time to upload the sketch: 1. Then pick those signals and connect them to the input pins of the potentiometer:Ĭonnect the output pin to the analog I/O pin A0: We’ll use those values to rotate the servo motor from 0° to 180°.įirst we create the circuit, then we’ll write the program.Ĭonnect the power pins 5V and GND to the + and - breadboard lines: In this arduino mini project we are going to develop a circuit using FLEX sensor, Arduino Uno and a Servo motor. Let’s attach a rotary 10k potentiometer, and adjust our sketch to enable us control of the motor by turning the knob. radio-controlled airplanes to position control. Using an analog input pin we can read the rotation of the potentiometer, with values ranging from 0 to 1023. Servomotor used in camera zooms, lift doors, or tools we may have at home. In this project we’ll see how to drive a servo motor using a potentiometer.
