Making an Encoder

• Programming Language: Arduino • 3D printing

• Function of Encoder - 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻 𝟭: we takes the value of the Photo Transistor(A) and We make the status of LED to be changed when the value has been changed. If the sensors are covered, LED become 'ON'. ('OFF' if sensors are not covered up)

- 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻 𝟮: If we run the code, motor rotates clockwise. And then outputs the rotation direction and the number of rotations. Once the switch is pressed in the process, the rotation direction is recognized through the photo sensor. Then it prints out the information about the rotation direction and the number of rotations. If the switch is pressed again, it rotates clockwise. And it also outputs the direction of rotation and the corresponding number of rotations.

- 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻 𝟯: The switch is pressed once, the motor rotates three and a half turns clockwise. Switch is pressed twice motor rotates counterclockwise.
