Week 6  Journal

I wanted  to create a smart dustbin. The idea is to design a bin that opens automatically when someone comes near. To achieve this, I plan to incorporate sensors, possibly infrared or ultrasonic sensors, to detect the presence of individuals in proximity to the dustbin. The goal is to make waste disposal more convenient by enabling the dustbin to open seamlessly when needed. It's an innovative concept that combines technology and practicality, offering a hands-free and efficient solution for waste management 

Electric Components:

• Mini breadboard, jumpers to connect the component

• IR Sensor  &servo motor

• Arduino Uno to read the input signals from the IR Senosr & accordingly, control the rotation of servo motor

other Components:

• cardboard 

• plastic 

• glue 

Inputs

IR sensor: sense an object 

Action

The servo motor rotates 90 degree angle for 3 seconds and then get back to start point . 

Brain

An Arduino UNO board will be used take inputs and generate actions

First I searched on Google the wiring diagram click here 

Then started following the diagram on my own circuit 

• IR Senosr , Servo Motor ,breadboard & Arduino UNO were inserted

•  breadboard was connected to the  5V for Arduino (5V as some were needed for servo motor and IR sensor ) represented by red wire 

• the black wire went to GND in Arduino 

• the signal of servo motor  wire orange was connected to pin 11 

• the signal of IR sensor yellow wire was connected to pin 7 

• by using code blocks, 

read digital pin 7 to low (in real life the IR needs to be low not high but in simulation on tinkercad it needs to be high )

so the servo motor simulated to rotate 90 degree for 3 seconds 

You can try it by using the following embedded simulation:)

Input components: IR Sensor 

Output component: Servo Motor 

Building the physical circuit

• The breadboard, Jumpers, IR Sensor , Servo Motor& ِArduino UNO were taken from the electronic kit

• The circuit was built physically (exactly as it was designed on Tinkercad) using the hardware components and wires

  •  breadboard was connected to the  5V for Arduino (5V as some were needed for servo motor and IR sensor ) represented by red wire 

  • the black wire went to GND in Arduino 

  • the signal of servo motor  wire orange was connected to pin 11 

  • the signal of IR sensor yellow wire was connected to pin 7 

• The Arduino board was connected to the laptop 

• The circuit was tested, and it worked successfully as shown in the video

i can use a sensor to sense the start of the game board or presence of avatars
