Hi everyone,

this week we learned how to use a servo motor with an Arduino
We used the sg90 servo motor:

Torque: 4.8V (1.6 kg-cm)
Speed: 4.8V 0.1 sec/60°
Weight: 9g
Dimensions : 23mm x 12.2mm x 29 mm
Rotational Range : 180°

In our project we will use 2 servo motors
Here is the code:

#include <Servo.h>
Servo servo;

int const potPin = A0;
int val;
int angle;

void setup()

void loop()
val = analogRead(potPin);
Serial.print(“val: “);
angle = map(val, 0, 1023, 0, 179);
Serial.print(“, angle: “);
On the next session, we will try to use the moisture sensor and the light sensor
