The AtHeart 4Duino combines Arduino, Wi-Fi and touchscreen

A new season, a new partner! We’ve had our sights set on 4D Systems’ touchscreen product for quite some time, and we’re excited to finally introduce that this Arduino and Genuino-compatible product is joining the AtHeart program. The 4Duino-24 is a 2.4-inch, 240×320-pixel Intelligent Display Module with Wi-Fi capabilities.

“For years Arduino/Genuino users have been taking advantage of our Intelligent Display Modules for adding graphical user interfaces with touch capability to their applications. With the 4Duino-24 we wanted to make something a bit more special and combine some of the more popular shields and the ATmega32U4 into a compact easy to use package. We are delighted to become part of the AtHeart program and very much look forward to seeing a full variety of applications running on the 4Duino-24.” – Markku Riihonen, Products and Business Development Manager, 4D Systems.

Perfect for your next creative IoT project, the 4Duino-24 runs on an ATmega32U4 MCU and is powered by the 4D Systems PICASO Graphics Processor that offers an array of display functionality and options for any designer and Maker. The 4Duino-24 also includes the popular ESP8266 module, which is pre-programmed with the AT command set firmware enabling the 4Duino to have Wi-Fi functionality right out of the box.

Beyond that, the 4Duino-24 is equipped with an onboard microSD connector and headers in the layout of an Arduino, including power pins (5V, 3.3V, GND and VIN), 20 digital I/O pins—seven of which can be used as PWM outputs, while 12 pins have analog input capabilities.

The 4Duino-24 can be programmed using the standard Arduino IDE or the 4D Workshop4 IDE and its three new 4Duino-based development environments with the added dimension of graphics. Creating Arduino GUIs doesn’t get any easier!

An even cheaper Wi-Fi board


For a few cents more than the ESP12F you get it with a programmer daughter board, a RGB led, a button and a photoresistor.
This is ideal for small robot with networking abilities.
Can be programmed with Arduino IDE as a NodeMCU v1.0 .

Internet-Connected TI-84

Just before the days where every high school student had a cell phone, everyone in class had a TI graphing calculator. In some ways this was better than a cell phone: If you wanted to play BlockDude instead of doing trig identities, this was much more discrete. The only downside is that the TI calculators can’t easily communicate to each other like cell phones can. [Christopher] has solved this problem with his latest project which provides Wi-Fi functionality to a TI graphing calculator, and has much greater aspirations than helping teenagers waste time in pre-calculus classes.

The boards are based around a Spark Core Wi-Fi development board which is (appropriately) built around a TI CC3000 chip and a STM32F103 microcontroller. The goal of the project is to connect the calculators directly to the Global CALCnet network without needing a separate computer as a go-between. These boards made it easy to get the original Arduino-based code modified and running on the new hardware.

After a TI-BASIC program is loaded on the graphing calculator, it is able to input the credentials for the LAN and access the internet where all kinds of great calculator resources are available through the Global CALCnet. This is a great project to make the math workhorse of the classroom even more useful to students. Or, if you’re bored with trig identities again, you can also run a port of DOOM.

What’s the future of board games? Some students are making it connected

Fifteen students from Master degree of ECV Aquitaine  under the direction of Tazas Project - an artistic group run by Guillaume Beinat and Alexandre Suné –  created and shared with us a smart board game called “Web World War”.

The goal is simple: survive a computer virus that has infected your machine and, throughout the game, the player should build a strategy  to win this virtual war.

The game runs on Arduino and is composed by a screenprinted board connected to any mobile device plugged on a local WiFi connection. Take a look at the video:
