35.- Arduino sends two random numbers with decimals, separated by commas. pA0_Bluetooth_Arduino_envia.aia (10.7 KB) float temperature = 0.0; float humidity = 0.0; String tempera_humidity; void setup() { Serial.begin(9600); } void loop() { temperature = random(20, 40) * 5.555; humidity = random(50, 95) * 3.333; tempera_humidity = String(temperature, 3) + "," + String(humidity, 3); Serial.println(tempera_humidity); delay(1000); } [bluetooth_basico34] [bluetooth_basico36]

Convert float to String.

String To_App = String(temp, 2) + " C";
BT.println(To_App);

14. Where do we connect the Bluetooth module in Arduino UNO? p9A0i_bluetooth_Serial.aia (2.9 KB) [bt_35] Terminals 0 (RX) and 1 (TX) are used by Arduino as the default Serial RX/TX. Use it to upload sketch, Serial Monitor, Bluetooth. So when we are going to upload a sketch for Bluetooth we must disconnect the RX cable from the Arduino. We can use other terminals to connect the Bluetooth module, for example 10 and 11, in this case we need the “SoftwareSerial” library. Now when we upload …
