Initial testing. Ignore the humidity sensor, that was for something else.
The vacuum gauge outputs 0-10VDC. This had to be changed to a 0-5VDC range using a potential divider so it was compatible with the Arduino. Initial build used a 10k pot in place of a vacuum gauge to make it simpler.

World’s first compact Arduino with integrated OLED+WIFI+SD CARD+32K SRAM for your 21st century projects! Play, create, embed, invent.
Piccolino (Italian for “tiny”) is a small, low-cost yet powerful programmable controller with an embedded OLED display and WIFI connectivity that you can program using existing tools like the Arduino IDE environment and the ESPlorer IDE. It uses the new ESP8266 LUA powered WIFI module which takes care of all the WIFI connectivity workload requiring only 3 lines of code in your sketches to establish a wireless connection. Furthermore, it can be configured both as an Access Point or a Station, so you can easily develop mobile device controlled appliances.

So we’re always cooking up hot new hardware in the Grav Corp labs. Recently, we’ve been working on a project using a 128×64 OLED screen with the SSD1306 controller. Adafruit is a good source of these displays, with an excellent library written by Limor Fried. The Adafruit_SSD1306 library makes it simple to use these displays with a variety of Arduinos, using either software or hardware SPI. However, we wanted a speed boost, and the Due looked like it could deliver, with its DMA (Direct Memory Access) capability.

Martin’s DIY Internet connected smart humidifier project:
The project uses a DHT22 temperature sensor mounted to the side of the enclosure for better ventilation and reliable reading:
I threw in a ultra-cheap I2C OLED status display to get a visual reading. Milling the box so that the OLED shows was pretty nasty, hated it. I cut a piece of paper and placed it on top of the cover, below the transparent lid to cover up for the lousy milling job
The humidistat switches on and off the humidifier as needed, the humidifier itself is plugged in to a plug in the relay. The auto detects when water is out and stops, so I didn’t have to care about that.

Even your device can be more user friendly thanks to various pictograms displayed on Winstar WEG series displays with a great contrast and viewing angle.
100×16 pixels at series Winstar WEG010016 isn´t that much at the first sight. But when we realize, that such display represents a sort of a “replacement” or “upgrade” of a character display (2×16-20 chars.), we´ll find, that it has wide possibilities of usage and it´s able to display much more than a character one.
Naturally, even a character display is able to display pictograms, but they´re limited by a given row or a matrix creating a given character. On the other hand, at a graphic display the whole area is available and naturally – it´s still able to display characters too.
Similarly like WEH series character displays, even the WEG series supports 4/8-bit interface „6800“/“8080“ and they have a built-in universal controller WS0010.
When we add advantages of OLED displays and attractive price, we have in hands interesting, universally usable display.

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!

I take a look at the YZXstudio USB 3.0 Power Monitor with OLED display which is sold by Franky – http://stores.ebay.com/99centhobbies
I demonstrate this very handy tool on a UBS power bank and show the issues with the USB voltage and losses across a USB cable.

The Pixelduino is a tiny Arduino-compatible microcontroller with a full color 1.5″ OLED display + MicroSD built-in!
The Pixelduino is an Arduino-compatible microcontroller that features a 1.5″ 128×128 pixel color OLED screen and a MicroSD slot!
There are all sorts of things you can do with a device like this. You can create wearables like a watch, bracelet, pendant, or buckle that displays color images, attach sensors and display data in text or visual form, display debug information, create a graphics user interface, or even make simple retro games.

This is an OLED clock I built using an Arduino Micro, a tiny OLED 128×64 display using the SSD1306 controller and I2C interface, and a precision DS3231-based real-time clock module with rechargeable battery backup. It features a menu system for setting the RTC (no serial port or USB required)

While TFTs have been the mainstay of displays for years, OLEDs are becoming more prevalent as their price drops due to the phenomenal increase in quality from TFT to OLED technology. We received this demo board from Newhaven that effectively illustrates side by side the differences between TFT and OLED technology, using a 1.69 inch 160 x 128 OLED display and a 1.8 inch 160 by 128 TFT display.
