Activities :
1. Functionality test on board.
π 25 August 2019
π This test is carried out to verify either Arduino UNO and Arduino WeMos can operate well or not. It is verified by compiling the Arduino coding from the example in the Arduino IDE 1.8.9 and run it in the hardware.
i) Arduino IDE 1.8.9 software is open to write the coding.
ii) After the sketch panel is open, click File >> Examples >> 01. Basics >> Blink.
iii) A new sketch panel will open which contains the basic example coding.
iv) The type of board used is set by clicking Tools >> Board.
vi) Step i) to v) are repeated for the push button using Arduino UNO.
vii) Step i) to iv) are repeated for the blinking of LED using Arduino WeMos.
Arduino WeMos board is connected to the COM port of the laptop using a USB cable.
The coding is uploaded into the Arduino WeMos board to run it and observed the board.
viii) The video of observation can be seen here >> Testing Functionality Board

π This testing was done to test the sound sensor's capability in detecting sound. A circuit of connection Arduino UNO with a sound sensor and LED was sketched using Fritzing software and constructed on the breadboard. For this test, the coding is uploaded into Arduino UNO to give instructions so that LED lights on every time the sound sensor detects sound. For this testing, the test has only been conducted using the sound of a plucking finger and humming sound.

π An oscilloscope is used to observe the waveform images. Waveform appeared when the sound sensor detects any sound. This sound sensor can detect well human voice and gives perfect waveform while if the sound comes from a machine, the waveform will have noise.
