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…
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…
It’s no the first time that we present a localizer without GPS. We remake the old device with the cheaper SimCom module SIM900. In the previous post we present the GSM section and now we can present the complete localizator. Introduction This system allows for localization without directly using GPS technology; we are able to…
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…
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….
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 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…
Let us start by describing the device’s electric scheme in its entirety, that is, along with all its components; we should also state in advance that the module we call GSM is, in reality, the small board hosting the cell phone, so the pin numbers refer to the contacts of the pin-strips that have been…
