In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Arduino and Telefónica have made this board compatible with the other network interfaces available for Arduino. Code written for the Ethernet or Wifi Shield can be adapted for this shield by changing ...

An Arduino is equipped with a piezo sensor to detect impact, and a GSM shield takes care of the texting. It’s an interesting concept, similar to requiring police officers to wear body cameras.

Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...

If you've mastered the art of Arduino, but haven't yet been brave enough to toss in a bit of GSM communication, the how-to guides linked below definitely deserve your attention.

Arduino has two new boards out which deliver connectivity – the Arduino MKR WAN 1300 (LoRa) and the Arduino MKR GSM 1400. The Arduino MKR WAN 1300 delivers LoRa low-power WAN connectivity, and the ...

arduino gsm security alarm Working of the system is very simple and self-explanatory. When input power is applied to the system, the system goes into standby mode. However, when the terminals of ...
