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...
