Week #6 Journal

Build and Program a smart circuit using an Arduino UNO which reads a signal from an input component to control an action component using Code Blocks  

I get inspired from google images and videos.

When the distance between the ultrasonic sensor become less than 10cm , the buzzer will produce sound.

Software Tools:

• Tinker CAD: to build the virtual circuit

• Arduino IDE: to upload the code to the Arduino board

• open Tinker CAD and drag all needed components.

• Unifying the ground by taking a black wire from( buzzer and ultrasonic sensor) then connect  with the board then from the board to the GND in Arduino Uno.

• connect +ve in breadboard with 5V in Arduino , then connect VCC in US-sensor with +ve in breadboard 

• Each Ultrasonic sensor has TRIG and ECHO pins which are connected with digital link.

• then simulate 

Tinker CAD coding 

• Open  blocks in tinker cad and starting to write the code.

• Picking an If then else condition from the control category.

• Drag comparison from math

• Drag the block of reading ultrasonic sensors at distance less than 10 cm.

• Then drag (set pin 4 to high) ,else (set pin 4 to low)

Challenge:
The code worked perfectly on tinker CAD but  actually there was a problem in connection of ultrasonic wire. So, I asked instructor Israa for help and she advised me to check connection. Hence, I checked it and I found that ttiggrr and echo pins were inverted.
