Automated saving coin box with notification via ESP module / Muhammad Nurhakimi Norizan

The significance of saving money nowadays is constantly being ignored by our generation, either youngster or adult which could lead to negative impact such as wasting money on unsignificant material and splurging on bad quality of lifestyle. If the problems are not properly dealt with, our younger generation will follow this unhealthy lifestyle and will indirectly foster extravagance lifestyle. With this perspective, this project presents an automated coin saving box with notification via ESP32 Lau module as wi-fi module to display coin value in box via application app. By using Arduino Mega as a controller, there will be two main systems which is system cash in and system cash out. Both systems use the same sensor, which is an infrared sensor. The value of the coins will be detected by their movement in and out of the automated coin box and the value will be recorded by the microcontroller, Arduino Mega 2560. Then, the value will be displayed on the LCD display and sent to the smartphone via ESP32 Lau. The simulation model was modelled using Proteus software and coding for the controlled was designed. On top of that, the hardware prototype of the coin box was also developed and operates successfully. The results show that the simulation model of the automated coin box system operates successfully and able to display the coin value on the LCD display properly. The hardware prototype also able to display the value on the LCD, and the system also automatically recorded the value via Dabble application in the user’s mobile phone devices.
