POTENTIOMETER AS ANGLE SENSOR

Tasks:

1. Add the potentiometer to the shaft of barrier gate. You can follow the instrucions in the video.

{#fig:pot_sen}

1. Test the potentiometer values with next program:

void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.println(analogRead(A3));
  delay(100);
}

1. Change the functions for lifting and lowering the barrier gate to use potenciometer readings instead of switch and time controlled movement.

[+] void setup() {   
[+] void loop() {
[+] void manualGateControll(){
[+] void stopTheGate(){
[-] void moveGateUp() {
        int gate_orientation = analogRead(POTENTIOMETER_PIN);
        while (gate_orientation < 750){
            digitalWrite(MOTOR_PIN_1, HIGH);
            digitalWrite(MOTOR_PIN_2, LOW);
            gate_orientation = analogRead(POTENTIOMETER_PIN);
        }
        stopTheGate(); 
    }
[+] void moveGateDown() {

1. Advanced: Calculate the angle of barrier gate from the analog readings of potenciometer.

Questions:

1. What is the value of the angle sensor when the barrier gate is in the upper orientation...
2. ... and in lower orientation.
