Week 6 - Journal

How the Circuit work:

The dice consists of one input component (the ultrasonic sensor) and two output components (the LED and the 7segment display). It works as follow: when your finger/hand come close to the ultrasonic sensor (distance < 20 cm) the Arduino board generate a random number between 1 and 6, then display it on the 7 segments display and the LED turns on.

Design on Tinkercad:

Firstly, I connected all the components on the breadboard and to the Arduino as shown, then I wrote the code for the Arduino by using the code blocks. Finally, I translated the corresponding C++ code to Arduino IDE to upload it for the real UUNO board.

Coding steps:

1- I made an if-else statement to monitor the readings of the ultrasonic sensor, so that if there is an object on a distance less that 20 cm the dice will work, and else everything turn off

2- In the working statement, I used random function to generate a random value between 1 and 6 and saved this value in a variable called "n"

3- then by using nested if, I began to inspect the value stored in the variable "n", and accordingly this value will be displayed on the 7 Segment display for 1 second
