The MicroGame is an experiment of making a custom portable platform for gamming compatible with Arduino. It’s based on a small monochrome 128×64 pixels OLED from Adafruit and a ATmega32U4 8-bits microcontroller running at 8MHz. All hardware design and game source code is writed from scratch by me and you can find all the files in my Github repository if you want to build your own. You can modify, share and make improvements as you like but do not forget to shoot me and email and show me your work!

For those of you who remember the eighties, this will no doubt bring back fond memories when every piece of audio equipment in the known universe was at the time equipped with a plethora of LEDs.
More specifically the ubiquitous Graphic Equaliser or ‘Graphic EQ’.
This Instructable is centred around the MSGEQ7 to create a simple 2 Channel Graphic EQ and documents my first, poor attempt at using the Arduino Uno R3, the Arduino development environment and coding in ‘C’ for well over a decade.

If you can beg, steal or borrow an Atmel ISP programmer, then you can use the Arduino environment to develop on the Atmel AVR Atmega328P Scorpion Board. An Arduino on Scorpion Board guide, Optiboot bootloader and example sketches have been added.
If you own an Arduino Uno board, you can now try out the Piconomic FW Library risk free without abandoning the creature comforts of the Arduino environment. You can use the existing Optiboot bootloader to upload code. I have added a getting started guide for the Arduino Uno. There are examples, including a CLI (Command Line Interpreter) Application that creates a “Linux Shell”-like environment running on the Arduino Uno so that you can experiment with GPIO, ADC, I2C and SPI using only Terminal software (for example Tera Term)… it is really cool!

Arduino Tutorial: GSM/GPRS SHIELD (SIM900) SMS Send and Receive Tutorial on Arduino Uno
In this video we are going to see, how easy it is to send and receive SMS messages using the Arduino GSM/GPRS shield (with SIM900 chip) from Tinysine. The shield is capable of sending and receiving SMS messages as well as making and receiving phone calls. It can also connect to the Internet using the GPRS network. But we will take a look at this later on in another video.
In this video, we connect to the GSM network of COSMOTE in Greece and we send an SMS message to a cell phone. Then we reply to Arduino and read the message in the Serial Monitor in the computer.

SAN FRANCISCO and MINNEAPOLIS, January 26, 2015 — Punch Through Design, a hardware and software development firm that brings Bluetooth Low Energy hacking to the masses, has released the Windows Bean Loader, the first-ever wireless Arduino programming app for Windows users. Using the loader app, Windows-based developers and hobbyists can easily upload code to their LightBlue Bean and experience the power of Bluetooth Low Energy, without cables or a physical connection to the LightBlue Bean.
“The LightBlue Bean represents a new method of wirelessly interacting with prototypes and projects; says Colin Karpfinger, founder and CEO, Punch Through Design. Previously, only Mac OS X and iOS users could program their Beans, and now we are extending that functionality to Windows users.
The full-featured app, available from the Windows Store, fills a void for Windows-based developers and DIYers looking to create smartphone-controlled devices.

So, first thing I did was to get the LCD and keypad working together.
For this I pretended that it was some sort of arm/disarm (or entry/exit) thing.
My code for this part is at: http://pastebin.com/YndLneqm.
Getting the LCD wired up was tricky as most wiring diagrams for it don’t show the last two pins wired up and these are required for the back light. Check my snazzy Fritzing wiring diagram to see how I wired up my LCD screen, pot (for adjusting brightness) and keypad. The pins for them all are also mentioned in my code.

In short: I developed a portable, battery powered device that sounds an alarm when your bag or purse is moved. Once armed, can only be turned off by your secret code.
The device is built off an Arduino compatible Trinket Pro, using an off-the-shelf project box with PCB.

In this Instructable, we will be building a compass using the TinyShield Compass as well as the Circle Edge Led shield.
After getting your boards and battery, the Arduino IDE will be the first thing to download if you have not done so already. When the IDE has been loaded go to tools, board, and select Arduino Pro or Pro Mini (3.3V, 8MHz) w/ ATmega328.

My son got one of these Leap Frog toys a few years ago as a gift. He enjoys playing with it very much. I am not sure how much counting and learning he is doing but it makes funny noises and sings to him so its a lot of fun.
Recently the unthinkable happened. It died. Not the batteries but something else. I took the back off to look at what might be wrong (which was very easy for a toy). Unfortunately, other than the speaker, a switch, battery compartment, and a ribbon cable to the front, there wasn’t much to investigate. A couple of glop tops and nothing else. I fiddled a bit more with it but everything “external” seemed fine.

I made a water level sensor a little while a go to measure the water level in my underground rainwater harvesting tank. Thanks to the Jubilee I found time to finally setup the first part of my Arduino/Xbee wireless sensor network and the first sensor node was also meant to read from this water level sensor. I was somewhat surprised when it only returned 0s so I went and had a closer look. How the slug got into the enclosure is still a mystery to me… but looking at the bright side (after the uncontrolled swearing) I now had a reason to build a much better water level sensor
