Hy, I don not know how to conect tow analog sensors in the same arduino uno. Could you tell my how,
One to A0 the second to A1 !?
U've got to tell 'more of the story'...
Hy, I want to connect a mini sound sensor, a ligth sensor and a servo motor
Connect the 'light sensor' (an LDR ?) in series with a resistor 10k+/-
5V to one end, GND to the other. common point (middle) to A0
Connect sevos 5V and GND (red,black wire) and control line (often orange) to pin 9
Then run this example from the servo library:
#include <Servo.h>
Servo myservo; // create servo object to control a servo
int potpin = A0; // analog pin used to connect the potentiometer
int val; // variable to read the value from the analog pin
void setup()
{
myservo.attach(9); // attaches the servo on pin 9 to the servo object
}
void loop()
{
val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023)
val = map(val, 0, 1023, 0, 180); // scale it to use it with the servo (value between 0 and 180)
myservo.write(val); // sets the servo position according to the scaled value
delay(15); // waits for the servo to get there
}
