A friend asked me to introduce electronic components in a simple way, not teaching electronics in depth, but giving just enough information to “play”. This makes sense: with a standalone Arduino board , You can make the onboard Led on … Continue reading
Some days ago a friend asked me how to build a device that periodically presses a push button. After some tought I came up with a simple solution using an Arduino and a servo motor.
There are times You need to be sure your application is always up and running, so You need a tool that resets the board if something goes wrong (crashes, infinite loops … and so on). This kind of tool is … Continue reading
After some intensive test of the GSM thermostat, I’ve decided to add new features and change some low level interactions with the GSM Modem.
This is my first “big” Arduino project so I decided to split the application into modules (read C++ classes), hoping to reuse these modules in future projects. So You will find a TempSensor_AD22100.cpp, a LatchedRelais.cpp, a SerialDebug.cpp, a ModemGSM.cpp and some other. The Arduino … Continue reading
The GSM Shield After some Web browsing we found a GSM Dualband Shield from Libellium (now outperformed by quadband device) that worked fine for this project even if It had some quirks that I had to solve via software. Libellium links the Shield Schematic and a tutorial that … Continue reading
