Activities :
1. Comparison of the components' price for the project

π Based on the table of the comparison above, it is better to buy components at Autobotic Sdn Bhd because does not need to wait for the delivery process. Autobotic Sdn Bhd is located at Block D, 12-4-1 (4th Floor, Jalan Semarak Api 3, Diamond Square, 53000 Wilayah Persekutuan Kuala Lumpur) and open every day on 9 am to 6 pm except for Sunday, thus I can walk-in to buy the component. Even though buy online on Shopee is much cheaper but needs to wait for the delivery process.

π Arduino UNO R3 Compatible Board is a microcontroller that used for interpreting data from the sound sensor. It is activated by implementing the coding in it as instructions of what it needs to do. The diameter for this board is 68.6 mm x 53.3 mm. Even though Arduino MEGA has a lot more memory space than Arduino UNO, due to only 1 analog input pin is needed to be used, Arduino UNO R3 is chosen instead of Arduino MEGA.
π Arduino WeMos D1 R2 WiFi UNO ESP8266 is a microcontroller that acts as a Wi-Fi module. It transmits and receives data via Wi-Fi connection to the end-user. The diameter for this board is the same with Arduino UNO R3 which is 68.6 mm x 53.3 mm.
π 9V Supercell battery is the most convenient battery to be used for the power supply as Arduino UNO R3 and Arduino WeMos operates on an external supply from 6 to 20 Volts. If supplied with less than 7V, the 5V pin may supply less than five volts and the board may become unstable. If using more than 12V, the voltage regulator may overheat and damage the board. Thus, the recommended range of supply is 7 to 12 volts.
