IOT 2.3 - Alasso

The document summarizes an experiment conducted using an Arduino Uno board to control multiple actuators for an IoT application. The experiment aims to assemble and control multiple actuators like servo motors, LEDs, and buzzers. The Arduino code written controls two servo motors by incrementing and decrementing their position from 0 to 90 degrees with a delay of 18ms between positions.

EXPERIMENT 2.3

1. Aim: Assembling and Controlling of multiple actuators using


Arduino Uno for any IoT application.

2. Objective:
To design and implement a robust and scalable system for the
assembly and control of multiple actuators using an Arduino Uno in
the context of an IoT application.

3. Components Used:
• 1 x Arduino Uno R3
• 2 x Servo Motor

4. Actuators:

• Servo motor:
Servomotors have three wires: power, ground, and signal. The power wire is
typically red, and should be connected to the 5V pin on the Arduino board. The
ground wire is typically black or brown and should be connected to a ground
pin on the board. The signal pin is typically yellow or orange and should be
connected to PWM pin on the board.
• LEDs:
LEDs (light-emitting diodes) are small, bright, power-efficient lights
commonly used in electronic products.
An LED light is a polarized part, meaning it has to be connected to a circuit in
a certain way to work properly. Specifically, each LED has a positive leg and a
negative leg. These can be identified visually by length: the negative leg has
been made shorter.

• Buzzer:
The buzzer is a sounding device that can convert audio signals into sound
signals. It is usually powered by DC voltage. It is widely used in alarms,
computers, printers and other electronic products as sound devices. It is mainly
divided into piezoelectric buzzer and electromagnetic buzzer, represented by
the letter "H" or "HA" in the circuit. According to different designs and uses,
the buzzer can emit various sounds such as music, siren, buzzer, alarm, and
electric bell.
5. Script/Code:

#include <Servo.h>

#define Servo_Pin1 3
#define Servo_Pin2 5
#define Servo_Pin3 9
#define Servo_Pin4 10

Servo servo1;
Servo servo2;

void setup() {
// put your setup code here, to run once:
servo1.attach(Servo_Pin1);
servo2.attach(Servo_Pin2);

servo1.write(0);
servo2.write(90);
}

int pos = 0;

void loop() {
// put your main code here, to run repeatedly:
for(pos = 0; pos <= 90; pos += 1){
servo1.write(pos);
servo2.write(pos + 90);
delay(18);
}

for(pos = 90; pos >= 0; pos -= 1){


servo1.write(pos);
servo2.write(pos + 90);
delay(18);
}
}
