Using Arduino and CH-05 Bluetooth module, modify the code to add a C switch statement. When buttons 1-9 are pressed on a cell phone app, the switch statement should decode the message (i.e. b1?, b2?, etc.) and print a more complex message to the Serial Monitor (i.e. Button 1 pressed, Button 2 pressed, etc.).

The code:

#include

const byte rxPin = 0; const byte txPin = 1; SoftwareSerial BTSerial(rxPin, txPin);

void setup() { pinMode(rxPin, INPUT); pinMode(txPin, OUTPUT); Serial.begin(38400); // Usually 9600 for BT mode, although it is sometimes 38400: BTSerial.begin(9600); }

void loop() { if(BTSerial.available()) { Serial.print("Rx Byte "); Serial.print((char)BTSerial.read()); } if(Serial.available()) { BTSerial.print((char)Serial.read()); } }
