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 ...

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.

[Bill2009] has made some nice progress on a control panel for his motorcycle over at the arduino.cc forums. It can show speed, tachometer readings for the wheel and engine, as well as indicate the… ...

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 ...
