Bluetooth add-on module lets Arduino connect with tablets and smartphonesJon Titus
// Bluetooth® Low Energy Battery Level Characteristic BLEUnsignedCharCharacteristic batteryLevelChar("2A19", // standard 16-bit characteristic UUID BLERead | BLENotify); // remote clients will be able to get notifications if this characteristic changes BLEDescriptor batteryLevelDescriptor("2901", ...
Even though my prototype was working quite well, there are still some issues. One of them is that the Bluetooth module gives audible pops on pausing and restarting playback. Another one is that I can't communicate to the Arduino if the music is paused or not and therefore can't put this...
The battery' voltage to Arduino's Vin pin need bestrictly7 to 12 volts, otherwise the board is unstable. Check with a multi-meter or voltmeter, while battery is connected to Arduino. If battery is flat, replace it. Ensure the Bluetooth is turned on, on the computer When Arduino is conne...
Wireless Connectivity– Adding Wi-Fi or Bluetooth for remote monitoring. Step 5: Conclusion This project combines technology and creativity to make plant care more engaging. Whether you’re new to Arduino or looking for a fun DIY build, it’s a great way to experiment with sensors and interact...
The PHY support was put together bySandeep Mistry, well known as the author of thenobleandblenoNode.js libraries, as well as theArduino LoRalibrary, amongst others. Built around thelwIPstack, it leverages thePIO, DMA, and dual-core capabilities of RP2040 to create an Ethernet MAC stack in...
IoT applications. The board includes: 1. OPTIGA™ Trust M security solution 2. PSoC™ 62, an Arm® Cortex®-M4/M0+ microcontroller 3. AIROC™ CYW43012, an ultra-low-power single-chip combo device featuring 1x1 dual-band 2.4 GHz and 5 GHZ Wi-...

Other people trying to build the project in Arduino IDE will need to know what to install. Ideally, I'd like to have Bluetooth mode turn on automatically if the device powers up but does not get a request via USB serial within x seconds (perhaps 3-5 seconds?). That way the setting ...
