We will equip Arduino with wireless connectivity basing on MRF24J4 module by Microchip. As a sample application, we will remotely control a relay, operated by a floating input, and we will virtualize the Arduino USB serial port. The MRF24J40MA radio module is manufactured by Microchip, that also provides useful and complete software libraries…
Here we present a small, low cost single channel receiver, encoding MM53200 and HT-12, with code self-learning function. Decoding is achieved by means of a PIC microcontroller by Microchip, that deals even to the memorization of 5 codes and governs the relay output as well. Features – Number of outputs: 1 – Output:…
After having seen the features and potentialities of RFTide modules, let’s see how to create a small network that has all the features of an advanced mesh network. To create a network with the RFTide modules, it is necessary to have at your disposal at least a Master unit. For the moment, let’s say that the…
Everyone likes comforts, you know, and that is why we all prepare ourselves, as soon as we can, to automatize some functions that otherwise we should manually carry out, thus inevitably taking up time and energies: from the irrigation system, to the tent that comes back automatically if too much wind rises; to the remote…
Since long past times, when Gugliemo Marconi has amazed the entire World broadcasting his radio signals from the Elettra ship, a subject held dear by electronic engineers has been radio transmission. After these years, the scenario has changed a lot, firstly with the appering of digital technologies (DAB, for instance) and, up to day,…
