Upverter is a community hosting schematics, blueprints, bill of materials, very often also full layouts. Today they hit an incredible goal, read it directly from their annoucement: “This morning, our community has publicly shared over 32,000 open...

With this post we are kicking off an official “Meet the Founders” column to let you get in touch with the best innovators, leaders and startup founders in the field of open and collaborative electronics and hardware....

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...

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 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...

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,...

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...

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...
