Let’s improve the 3Drag with this new board that allows to control a fan and (thanks to the ATmega2560 processor) add some code and accessory devices such as a display or an SD Card When we first released our 3D printer, we tried to use some parts that were already available and tested, in…
Often, during your first experiences with Arduino, you use the Serial Monitor, a feature available in the IDE, which allows you to display values on the screen. However, if we you want to display values or strings locally on the board, it would be very convenient to have a small display and a few…
Someone had already imagined, someone else hoped for that, days ago, finally one of the most prominent actors of the Makers ecosystem, Makerbot, announced a commercial desktop 3D Scanner. The good news, for those concerned with the openness of such a system, is that, well before that move, developers already created it: it…
We wanted to create a basic tool to experiment with the RN-42 Bluetooth module so we created obviously a Demoboard. The RN-42 Hardware module The RN-42 is a Bluetooth 2.1, Class 2 module with a PCB integrated antenna with a communication capability of about 3 Mbps. The version with the integrated antenna has…
Let’s learn about hardware and software features of the open source 3D printer from Open-Electronics. Among the advantages of open source hardware and software lies the ability to know all the construction and design details and have access to all the parameters to change the device operation in details. We have all the information…
Cheaper electronics and network connectivity are driving the Internet of Things, that’s our idea to let your object interact with you. If you are a new user in the world of Arduino (and similar) microcontroller boards, maybe you came across the idea to control objects around you, interconnect them and have remote interactions. This is…
NEWS! Access the schematic of the printer here on the Rep Rap Wiki Few months ago, after long months of testing, assembling and disassembling, print trials,and countless sleepless nights we finally decided to give birth our interpretation of the RepRap project. First steps When we picked up the first RepRap kit, an elaboration of a…
IKEA’s Figgjo, is designed to be a mirror, but with a little ‘electronic can becomes fascinating light equipped wall clock. It’s a round mirror, from which twelve evenly spaced rays and this makes it perfect for a clock base. The twelve rays with small round mirrors will be our hours, while the circumference of…
There are many shields available almost for every application. Today we want to show you how to use your Arduino as a wheater station which can be improved, unlike commercial products that cannot be expanded or easily modified. Our shield uses three analog sensors in order to measure enviromental temperature, relative humidity and atmosferic…
. 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 on the SIM900 GSM module. We released schematics and code for a gate opener (that activates when receiveing…
Today we introduce you a robot fish that is able to swim and recognize tank edges and obstacles. We’ll find out how we can easily create it with common insulating material and a few servo motor controlled by Arduino.

The idea Ardusumo is a universal platform to build robots on wheels that can move around avoiding obstacles using infrared sensors and follow routes marked with dark lines on a white background. We have created Ardusumo to bring young students to the world of robotics: if suitably programmed, Ardusumo allows robots to perform various…
