A lot of people who bought the TiDiGino ask me how to test it.
The Gsm Remote Control is provided with bootloader, so you have to insert the prefered sketch that you can find in code.google.
Daniele Denaro wrote a good sketch for TiDiGino, and I’m reporting his tutorial.
Ask me (and him) all do you need.

Using an ATmega 2560 and therefore the heart of Arduino, we have developed a universal remote control with GSM. This allows  to control 2IN/2OUT, DTMF key, gate control and GSM thermostat activated remotely.

We have already presented several remote control with different functions.
But now we want to present the best remote control ever made with Arduino.
The remote control is easier, thanks …

 The Contest is close, visit the TiDiGino page
The project TiDiGino
We developed a new GSM remote control called TiDiGino. The name recalls the initials (TDGxx) of our previous GSM remote control and is also based on the Arduino project. All the details of this circuit can be found below, but no the sketch, because this is your assignment.

The contestYou have to write the firmware for this project.  The device must perform all the functions …

Some post ago we presented a PCB to mount the SIM900 module. The projects is used in our GSM remote control and the Arduino GSM Shield.
The dimensions aren’t big (1.75×1.95 inches) but in some cases they are too important for a projects, so….

..we have developed a small PCB GSM module to build device like localizators (coming soon… ), bugs or other …

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.

In the articles devoted to the remote GSM modules, we have repeatedly mentioned that the programming of the numbers in …

Allows to remotely manage the heating or cooling of any room. It can also notify, via SMS or phone call, when the sensed temperature falls out the set limit value or the alarm input is active.
In Summer As well as in Winter, it may be a good idea to install at home as well as in your holiday house, a …

The entire remote control is handled by a PIC that controls the GSM/GPRS module’s activity and gives commands to the two relays.
Having said that, let’s take a better look at the electric scheme: power is supplied by continuous voltage, not always stabilized (applied to PWR + and -) at a value between 5 and 32V; such voltage is filtered at …

The full GSM thermostat is managed by a Microchip PIC18F46K20-I/PT microcontroller, programmed with a firmware that controls the temperature and takes care of the communication with the GSM module which is the component named GSM; this is, in fact the small board hosting the cell, so the pins’ numbers refer to the used pin-strips’ contacts.
The firmware reads the room temperature …

Excellent to remotely control via GSM the activation of engines, lightening or watering systems and alarm systems. It sends commands through SMS as well as with DTMF dual tones and allows you to check if they were successful.
In this post we present the last application created from the development of the modular remote control we started describing in the issue …

For the GSM temperature controller we have provided a double-sided PCB with plated holes, made by photoengraving; once you have the board you can start the assembly with SMD components.
The thermal probe can also be mounted out of the PCB, connecting it somewhere else by means of a three-conductor cable, at least 20 meters long.

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, obtained by adding to the regular circuit, two optocouplers and both relays, together with the basic components. The circuit we propose has two main …

Let’s now look into the schematic diagram; in it you can note the usual Microchip microcontroller governing the GSM/GPRS module activity, controlling the logical condition of the two opto-isolated inputs and managing the two relays. Moreover, the PIC interacts with the DTMF decoder in order to recognize the dual tones used for the phone selection in modern telecommunication systems; it …

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 firmware that controls the GSM/GPRS module’s activity, reads the logic condition of the two opto-isolated inputs and sends commands to the two relays in the …

On the construction perspective, the remote control does not present many difficulties, just the obvious ones that appear when working with circuits requiring superficial assembly components. As usual, there is a PCB with double plating where to mount all components.

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 components, all this in order to reduce the overall size of the device.

The set of commands of this remote is divided into two categories: the SMS ones and the DTMF tones.
The former are simply summarized in the corresponding table, since they are the same as the ones described for remote 2 IN/2 OUT.
Here we will only describe in detail the DTMF commands, first stating that unlike those from SMS, that can be …

Commands can be given in two different ways: the first one is to send the SMS according to required syntax and with the password (if required), needful to avoid strangers to operate the configuration; the second one is to introduce, through Easy Setup, the number of the mobile enabled to make the following settings via SMS.   In that case a …

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 separated; some commands, due to their importance, they require a password which is 12345, set by default during the first activation of the …
