A FT-232 USB to serial board is used to program the Arduino. A standard Bluetooth module has to have HID firmware installed. ... you’ll have to remove it before uploading new code.

The project is build around an Arduino ProMini, an FTDI breakout board, and a Bluetooth module. It’s a fairly simple build, but the meat of the project lies in the code .

How, then, do you get your phone to send specific serial signals to your Bluetooth module, receiving feedback as needed? We combed through the Google Play store to figure out which are worth ...

Check out the video below to learn more about the Bluetooth THINGY module. “We have all said it a 100 times, if we only had an App to tell us if our garage door is open late at night.

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

To support this platform, Arduino hardware already features on-board crypto-authentication chips and certified comms modules spanning Wi-Fi, BLE, LoRa, LTE Cat-M, and NB-IoT.

Introduction:In Arduino environment, it's convenient to access BT SPP like a serial port and react to the command string sent from the BT serial port. Many Arduino projects have utilized this way ...
