We emulate the TDG series remote controls using the GSM Shield. It’s not been long since we presented our GSM shield for GSM/GPRS modules SIMCom, QUECTEL, FIBOCOM etc. that was born to be incorporated in Arduino-based projects...

  A new useful and intuitive Android app to easy manage our TDG133 GSM remote control. In this blog we often use the SIM900 GSM module for remote control applications, like the TDG133 (2 IN / 2 OUT) ,...

PC configuration software for all remote controls described in the last four issues. This application is used to set all parameters via PC, instead of using the boring and expensive SMS configuration system. Download “Configuratore TDG v.2.3.0.0”...

It allows you to remotely control up to two different electrically controlled units and to remotely read the condition of as many devices or the presence of tension on power lines. We describe the simple remote control,...

In order to understand the different functions, let’s now take a look at the schematic diagram of the unit. 2 IN and 2 OUT Schematic Diagram The entire control is handled by a Microchip PIC18F46K20-I/PT microcontroller, programmed with a...

Now that we have seen the electric scheme, we can work on the practical aspect of the project; let us state in advance that its making presupposes a double-faced printed board with metallic holes, using many SMD...

Now you have to get to know the commands needed to manage it and use them at their best.  Relevant commands must be given by SMS, on the understanding that a message can contain multiple messages properly...
