Servo Motors

Servo motors is a motor which rotates in a specific angle. 

In Arduino, the hardware required are:

-Arduino Board

-Bread Board

-USB Cable

-Wires

-Servo motors

First connect Red wire of servo motor with another red wire to 5V,  Brown wire of servo motor with Black wire to GND and Yellow wire of servo motor with white wire to -9V of Arduino board.


Then the code used is sweep:

#include <Servo.h>

Servo myservo;  // create servo object to control a servo
// twelve servo objects can be created on most boards

int pos = 0;    // variable to store the servo position

void setup() {
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}

void loop() {
  for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees
    // in steps of 1 degree
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15 ms for the servo to reach the position
  }
  for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15 ms for the servo to reach the position
  }
}


Lastly the outcome after running the code and outcome:





Finally the servo starts rotating from (0 to 180) degree and (180 to 0) degree.

LED Lights

 The hardware required are: -Arduino Board -Bread Board -LED -USB Cable -10k ohm Resistor -220 ohm Resistor -The led light with basic code Firstly connect the three wires:  Red wire from bread board to 5V, Black wire from bread board to Ground GND and White wire from bread board to Analog input A0. Also, insert the LED light in GND and 13V. Then from the basic code AnalogReadSerial: // the setup routine runs once when you press reset: void setup() {      pinMode(LED_BUILTIN, OUTPUT);   // initialize serial communication at 9600 bits per second:   Serial.begin(9600); } // the loop routine runs over and over again forever: void loop() {   // read the input on analog pin 0:   int sensorValue = analogRead(A0);   // print out the value you read:   Serial.println(sensorValue);   delay(1);  // delay in between reads for stability     digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level) ...

  Activity 1 - Real Users For the following pictures decide what existing or fantasy input/output devices would benefit them. Remember people have five senses sight, smell, taste, touch, and hearing, so you might want to create devices for each of them – there is also the possibility of direct brain input.             According to the pictures, these might be the input and output devices that would benefit them.
