Week 6 - Journal

started to wire the components

1. connected the 5 Volt and Ground Terminals of the Arduino to the breadboard

3. connected the first terminal of the push button to the +ve of the board and the other terminal to digital PIN 2 of the Arduino 

 4. Make a connection between the second terminal of the push button and the ground by adding 2 k resistance in parallel to it to be a pull-up resistance (to avoid floating status)

5. wrote the code using code blocks

This is the Code written in C 

Could you let me know what this code does?

This circuit is simple, it consists of an input(Push button) 

When the button is pressed it makes the servomotor (Output)

rotate by a certain  angle 

To make Arduino take the input, and process it to give us the output we have to write this code

1. Include the library of servo so the Arduino can deal with it

2. Name the servo so we can deal with it later and 

3. define the input PIN 2  (push button) and output action(servo)

4. Attach Servo to PIN 4 and gave it the range of Values

5. make the Arduino read from the input (Button ) process the info received and then give the output (Movement of servo )

• if it takes 1 (button is pressed ), Arduino gives the order to the servo to move by 90 degree

• if it takes 0 (button is unpressed ), Arduino gives the order to the servo to move back to the 0  degree

We can take it from Tinkercad but this code has to be tweaked for the input to be INPUT_PULLUP instead of INPUT to be working functionally
