A followup to the Embrio – a visual programming environment for Arduino post. Ezra Schwartz, maker of Embrio, just posted a new version of the software with better functionality for writing Arduino code right into a visual node: Embrio lets you create the logic and structure of your programs with it’s powerful “agent based” architecture, but also […]

Arduino decision box BE (Attiny85)
nqtronix wrote this instructable detailing the build of his Arduino Decision ‘Box’ BE (Breadboard edition): Pleace notice: This project neither contains a box nor any Arduino* code. I stuck with this name because this project is a modifictaion of Victor8o5’s “Arduino decision box 2.0 (Attiny85)” posted three days ago. I liked the way it looks and works, […]
The Bipolar ORD Bot
The Bipolar ORD Bot at Buildlog.Net by Barton Dring: This was built and programmed gonzo style in about 2 evenings. The sole purpose is to spark conversation at ORD Camp 2015. The machine uses two polar axes to create the motion. It is running off stock grbl 0.9g on an Arduino. It runs standard gcode that is […]
Embrio: A visual programming environment for Arduino
Embrio, create Arduino programs without writing code: Easy To Use -Make programs by adding and connecting nodes. No coding necessary! Real Time Connection -Work with a live connection to your Arduino, see how your program works as you build it! Powerful -While easy to use, Embrio is a powerful development tool that you won’t outgrow […]
Piccolo, a tiny CNC bot
Luca Dentella blogged about his Piccolo build: Piccolo is an opensource project, by Diatom Studio, that consists of a small CNC bot (working area about 5x5cm); the official site is www.piccolo.cc. I built one unit; the required components are: the frame, laser cut by Vectorealism 3 micro servos, brought from HobbyKing screws, nuts… the PCB (manufactured by […]
Open source laser cutter
Martin Raynsford has written an article detailing his open source laser cutter project: Now that I have an easy way to switch controllers into my laser it’s time to try out some of the different softwares. I’m quite comfortable with Arduino and I’ve got a fair few of them kicking round my house so that’s […]
Programming Arduino Pro Mini with Bus Pirate
Dana Harding writes: Program an Arduino Pro Mini 328 [sparkfun] board using a Bus Pirate. I tried setting up the Bus Pirate as a transparent bridge for UART to use the Arduino boot loader. I got as far as manually sending 0x30 0x20, and receiving a 0x10 0x14 – establishing communication over UART… But couldn’t get […]
Arduino Uno R3 graphics accelerator shield uses no pins
Andy Brown has written an article detailing his Arduino graphics accelerator open source project: This project brings together the knowledge that I’ve gained over the last few years to bring you a graphics accelerator for the Arduino Uno R3 based on an ARM Cortex M0 core attached to a 640×360 LCD from the Sony U5 Vivaz […]
DirtyPCBs: HDC1000 temperature and humidity sensor breakout, with Arduino library
Francesco Truzzi published a new build: a breakout board for the TI HDC1000, a tiny (8BGA) temperature and humidity sensor The boards were again fulfilled by DirtyPCBs, perfect for this kind of small projects. So here are the pictures of my board and here are the features: Address selection jumpers: ADR0 and ADR1 are tied to […]
DirtyPCB LSF0204 breakout board – a bidirectional, multi-voltage level converter
Francesco’s LSF0204 breakout board, a 4-bit, bidirectional, multi-voltage level converter: I needed a small, fast and reliable multi-voltage level translator (mainly for connecting ESP8266 boards to the Arduino, got tired of resistor networks pretty quickly) so I built a breakout board for TI’s LSF0204(D). Datasheet and info here. The LSF0204 is a nice little chip. […]
Arduino: 3 powerful, yet overlooked uses
Daniel over at Bench Talk /Mouser blog writes: Most engineers cringe when they see an Arduino in my toolbox. Their reaction is partly due to the fact that Arduino is often viewed as being too easy to use or just not feasible. For the most part, they are correct, but that’s not what I’m here to […]
5″ capacitive touch panel with GSL1680 up’n running with Arduino
Helge of WeatherStation writes: After some help from wolfmanjm and CosR1, I managed to get a separate Buydisplay based GSL1680 touch panel up’n running on an Arduino Mega (1280) with only minor modifications to wolfmanjms code. The firmware is an integrated part of the sketch. Instead of using ram, it is put in the flash […]
Arduino equipped inline sensor skates
Anurag Mishra writes, Recently I bought a new pair of Inline Skates. So an idea struck my mind. I modified my skates to give me some results. I wanted to measure the speed with which I am skating and if I get to know the surrounding conditions, that would be awesome. So, I brought an […]
Teensy SDR project
rheslip made this Teensy SDR project, that is available at Github: I managed to get the Teensy SDR in an enclosure over the Christmas holidays – now its starting to look like a radio! The enclosure is a plastic Hammond. Front and rear panels are PCB material and I added a layer of PCB inside […]
3DRacers, a 3D printed indoor racing game based on Arduino
3DRacers, the open source 3D printed racing game that you control with a smartphone: 3DRacers are 3D printed race cars that you can customize for free with their online editor. Once you have downloaded and printed your design, the electronics are a snap. The 3DRacer team has created an Arduino compatible control board that fits […]
Power plug energy meter – Now wireless!
Kalle Löfgren writes: Today’s post will cover how I managed to get an Arduino pro mini (3.3V) to sniff the energy meters SPI and transmit the data wirelessly with a nRF24L01+ to an Arduino Nano connected to a computer. The neat thing with this setup is that the Arduino pro mini and the nRF fits […]
A world of MQTT on ESP8266
Peter Scargill has written an article ‘the world of MQTT on ESP8266: The obvious choice was a local copy of MOSQUITTO – the free package designed, apparently by Roger Light. A simple DOS application which can also act as a service. Marvellous. Now I needed to put the code into the ESP8266 – that worked – […]
A Classie WSPR transceiver
joesugar over at Computer/Electronics Workbench writes: Because of my location, amateur radio operations are limited to low power and disadvantaged antennas. Therefore, the WSPR (Weak Signal Propagation Reporter) protocol immediately caught my eye when I first ran across it. My primary interest is building, so I put together a stand-alone beacon using an Arduino and […]
MIDI Christmas tree
A MIDI Christmas tree by Peter Marchant: Using an Arduino and a SparkFun MIDI Shield to control Christmas Lights with a MIDI keyboard. The lights cycle colour (green, red, blue, orange) for each note or chord. Imrpovisation based on the minor blues scale on D. Via Hacked Gadgets.
HC-05 Bluetooth link with zero code
Phillipe Cantin writes: So you want to two HC-05 modules to automatically connect together, as soon as they’re powered up and with zero code? Well this is your lucky day since this can be done using the AT+BIND command. Let’s do this thing! For this, you will need: 1 Arduino (I’m using UNO) 2 HC-05 […]
