We’re a Finnish start-up company which specializes in active green walls which can purify air 100x better than traditional green walls. Few years ago we were in a need for easy way to get our green walls...

. Connected to a burglar alarm or fire alarm in the event of making phone calls playing voice messages. Controlled via DTMF actuators can operate on the spot. In recent years we have introduced several telecontrols based...

Shield for Arduino designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS.     HARDWARE INNOVATIONS This new version (old Arduino GSM...

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...

  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...

   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...

Some post ago we presented a PCB to mount the SIM900 module. The project 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...

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″...

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...

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,...

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...

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...

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,...

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...

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...

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...

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...
