Arduino project: IR sensor control

This week's assignment is to build a smart circuit using an Arduino UNO which reads a signal from an input component (Sensor, Switch, or variable resistor) to control an action component (Motor, Buzzer, LED...etc) using Code Blocks.

I used Arduino project Hub to get inspiration from one of the simple projects that fit the criteria.

And I settled on doing an electrical circuit in which the IR sensor senses the infrared rays emitted by the human body and infers the presence of the human being or not by lighting the lamp.

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

software

materials

IR SENSOR

LED

ARDUINO UNO BOARD

Male to Female wire

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

The circuit consists of an IR senor and a LED , they are controlled through the Arduino.

When the IR sensor senses the infrared ray and senses the presence of any object in front of it, it gives an alarm through the LED light.

And when the body disappears, the LED goes out.

-First I built the circuit on tinker cad

Then I started writing the code as a block.

I converted the code from the block to Text in TinkerCAD and then copied it in Arduino

To be ready for uploading .

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

I connected the negative terminal of the LED to GND and the positive terminal to pin 13 .

As for the resistor, the first pin I connected to 5 volts, the second to GND and the third to pin 2.

Then I connected the Arduino board to the computer through the USB connection,And you uploaded the code

Then , the circuit worked.

Where when I put my hand in front of the sensor, the LED lights up and when I take it off, it turns off.

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?
