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)
  delay(SensorValue);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);     // turn the LED off by making the voltage LOW
  delay(sensorValue);                      // wait for a second
}

Lastly after running the code and connecting the wires, the outcome is:



Also, you can change the speed of light by covering or without covering your hands.

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.

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);   ...
