We will rebuild a BarTop arcade coin-op machine to rediscover the charm of the 90s: just a Raspberry Pi, one shield described here, a LCD screen and a few buttons. What is an Arcade game? Probably you heard or read this term many times, but if you aren’t at least 35-40 years old,…
It supplies Arduino with the WiFi connectivity and the external memory support on a SD-Card; it is based on a new module that is completely programmable, and offers the best value for money, with a very limited energy consumption that make it ideal for battery applications. It is not the first time that…
In this last post of the LoRa series we will see how to use the board, so to create a network composed of addressable and safe nodes. Semtech’s SX1278 integrated circuit, on which this shield is based, allows for a sophisticated and efficient communication in the LoRa (Long Range transmission) technology. This communication is…
In a previous post, you had the opportunity to discover a new Shield for Arduino, based on Semtech’s SX1278 chip that, in view of a very limited price, allows the implementation of a radio communication for a wide range of applications: from the transmission of digital signals in OOK or FSK mode, to the…
Let’s substitute our 3D printer’s command panel with a dot-matrix that enables the display of graphics, function icons and animations. We would like to remind you that our 3Drag printer (that prints plastic items of the size of 200x200x200 mm) may be supplied with a command panel, so to locally manage the printing…
Let’s create a multi-function LED lamp, always connected via wireless, thanks to Arietta G25. Since several years already, it is possible to find systems for home automation: irrigation, doors and windows, lighting, air conditioning and alarm systems, everything can be centralized and planned. Recently, the classical control boxes have been replaced by smart…
A new useful and intuitive Android app to easy manage our TDG133 GSM remote control. In this blog we often use the SIM900 GSM module for remote control applications, like the TDG133 (2 IN / 2 OUT) , TDG134 (Gate opener), TDG139 (Temperature control) and TDG140 (2 IN / 2 OUT with DTMF) remote controls. They are home automation devices that…
Let’s equip Arduino with a long-range communication module, and one based on Semtech technology. In this post we had the chance to talk about two technologies that compete for the market of the low-energy, long-range (few kilometers) wireless communication: that is, the SigFox and LoRa technologies. It is now the time to transfer…
After the first installment about the hardware, here we deal with the software to be loaded in the Raspberry Pi board and the RandA’s firmware, needed in order to make our automatic bartender machine operational. In the last July’s issue we proposed a project that, even if probably unusual, was undoubtedly fitting for…
A Low Frequency (i.e. audio LF) amplifier for many uses, able to drive small speakers in portable or stand-alone devices with maximum efficiency and without needing heat sinks. Particularly suitable as final stage for MP3 players and portable audio players. As the “hunger for watt” is insatiable, the demand for LF low power…
Let’s experiment and prototype applications via the wireless board based on the ESP8266 module. Let’s get back to the discussion of the ESP8266 chip, in which we described the new Fishino board, whose major elements are the ATmega328 microcontroller and the ESP03 module, the latter being based right upon an ESP8266 chip. In…
Geared with a shield containing an HCS Microchip encoder/receiver module and an I/O Expander I²C-Bus board, it enables the creation of Arduino based remote controls with 8 channels, expandable to 12. The great amount of remotely controlled devices that already are in our houses (and even beyond), made us look at the issue…
