Re: Reading the angle of a shooter
A potentiometer is used for analog reading. A potentiometer increases in resistance as it is rotated if it is placed on the axis of rotation then as it turns/changes angle the potentiometer it will output different voltages that the robo rio can read.
Another option is to use a gyro scope which measure the rotation of things and outputs a digital signal to the robo rio
A third option is to use a encoder on the motor that changes the angle amusing you use a motor
And final you can use a camera and vision processing and the reflective tape on the tower high goal to find your angle.
