With Arduino Mega, we create, a keyboard with RFID module, a configurable access control system, to manage electric locks. In the market there are different types of controls for electric locks: from the simple insertion of codes to biometric readers, passing through transponder readers (RFID) or magnetic strips. The project that we present…
In the previous episode, we have described the library and the functions made available by it. Now we will introduce a series of sketches through which you will see in practice how the library works and it’s potential. The sketches will implement functions such as receiving or sending SMS, voice calls, managing certain generic…
Let’s discover a useful library to manage various low-cost GSM/GPRS modules, in order to provide cellular connectivity to our Arduino projects. Second part. In the previous episode, we introduced the shield hardware and exposed the technical features and possible applications, as well as mentioned the library for Arduino, here we complete the previous speech…
It supports various low-cost GSM/GPRS modules in order to provide cellular connectivity to our Arduino projects. First part. Given the growing demand for electronic equipment with connection to the GSM/GPRS network, we decided to develop a new GSM shield for the Arduino and Raspberry Pi 3 platforms, capable of supporting various modules on…
