The Arduino IoT Cloud platform aims to make it very simple for anyone to develop and manage IoT applications and its REST API plays a key role in this search for simplicity. The IoT Cloud API at its core consists of a set of endpoints exposed by a backend service, but this alone is not enough to provide…
Let’s call back an electronic version of one of the most famous casino games: no tricks and no cheats… The “roulette” is without a doubt one of the most famous and practiced casino games in the word, and it is surely one of the most widely employed, along with poker, in famous movies from…
Smartwatches can keep us informed of incoming information at a glance, but responding still takes the use of another hand, potentially occupied by other tasks. But something is about to change thanks to the WrisText system. We present WrisText – a one-handed text entry technique for smartwatches using the joystick-like motion of the wrist. A user enters…
Using an ATmega 2560 and therefore the heart of Arduino, we have developed a universal remote control with GSM. This allows to control 2IN/2OUT, DTMF key, gate control and GSM thermostat activated remotely. We have already presented several remote control with different functions. But now we want to present the best remote control ever…
When you walk into a dark room, the first thing you naturally want to do is to turn on the light. But who touched that light just before you? Is it worth the risk, or better just to stay in the dark? You no longer will have to face this dilemma with the “don’t…
The SparkFun Pro nRF52840 Mini Bluetooth development board is now available priced at $30 and features a ARM Cortex-M4 CPU supported by 1MB internal Flash and 256kB internal RAM. The board comes pre-programmed with a USB bootloader. You can develop programs for the nRF52840’s Cortex-M4 using either Arduino, Circuit Python, or C (using Nordic’s nRF5 SDK),…
