Hi Everyone,
I have this code (below) that reads a photoresistor and then move the servo small amounts depending on the light reading. My code seems to be correct, but the servo keeps glitching - it moves to 90 degrees at the beginning of the program and then sits at around 10 degrees for the remainder of the time, no matter what I make the light reading.
CODE:
#include <Servo.h>
int sensorValue = 0;
Servo servo_3;
void setup()
{
pinMode(A0, INPUT);
Serial.begin(9600);
pinMode(9, OUTPUT);
servo_3.attach(3);
}
void loop()
{
// read the value from the sensor
sensorValue = analogRead(A0);
// print the sensor reading so you know its range
Serial.println(sensorValue);
// map the sensor reading to a range for the LED
analogWrite(9, map(sensorValue, 0, 1023, 0, 255));
delay(2000); // Wait for 1000 millisecond(s)
if (sensorValue < 100) {
servo_3.write(0);
}
else if (100 < sensorValue < 200) {
servo_3.write(9);
}
else if (200 < sensorValue < 300) {
servo_3.write(18);
}
else if (300 < sensorValue < 400) {
servo_3.write(27);
}
else if (400 < sensorValue < 500) {
servo_3.write(36);
}
else if (500 < sensorValue < 600) {
servo_3.write(45);
}
else if (600 < sensorValue < 700) {
servo_3.write(54);
}
else if (700 < sensorValue < 800) {
servo_3.write(63);
}
else if (800 < sensorValue < 900) {
servo_3.write(72);
}
else if (900 < sensorValue < 1000) {
servo_3.write(81);
}
else if (1000 < sensorValue < 1100) {
servo_3.write(90);
}
}
If you can find any issues and tell me how to fix them, I would greatly appreciate it!!
Thanks,
