Store description excerpt

After mounting the Wi-Fi module on the Arduino board, operating this app on the mobile phone to connect the Wi-Fi communication between the mobile phone and Arduino, pressing the 10 buttons provided on the mobile phone to recognize the pressing of the button on the Arduino to perform the desired operation. app that allows - Single button: 10 (Data sent to Arduino when each button is pressed) Button 1: ‘0’ (hexadecimal 30) Button 2: ‘1’ (hexadecimal 31) Button 3: ‘2’ (hexadecimal 32) Button 4: ‘3’ (hexadecimal 33) Button 5: ‘4’ (hexadecimal 34) Button 6: ‘5’ (hexadecimal 35) Button 7: ‘6’ (hexadecimal 36) Button 8: ‘7’ (hexadecimal 37) Button 9: ‘8’ (hexadecimal 38) Button 10: ‘9’ (hexadecimal 39) (Example of program in Arduino) LED connected to digital port 5 of Arduino turns on when button 1 is pressed once, and turns off when pressed again.
