This is a very simple LCD display that has a two wire serial interface. It displays characters, not pixels. It can show 20 characters in a row and 4 rows. They are fairly inexpensive at retail - only about $10. They have a toggleable backlight and a variable contrast.
Before trying this code, make sure you have ensured that your camera works because you will not be able to see what is happening with the camera while it is saving to the SD card. If you are having issues with this, please check out the Evaluation Software provided by Linksprite.
The Adafruit Ultimate GPS Breakout board is an excellent way to get started with GPS and Arduino. Adafruit does an excellent job providing tutorials and code for the user. I would suggest checking out their provided tutorials and code before looking elsewhere.
I had gotten a joystick a while ago and wanted to do something different and interesting with it. After coming up with and discarding a bunch of other ideas, I came up with the Arduino Sketcher. The ideas was to make something similar to an Etch-a-Sketch but uses the joystick instead of two…
Joysticks have become a common tool among various devices, such as gaming controllers. They can be an interesting addition to projects as well. Joysticks are fairly simply components that use two potentiameters to give the readings from two axes. They may also include a button to see if the user…
Who hasn’t wanted to monitor what goes on when they aren’t there. When I was little, I was always curious about whether or not anyone was going into my room and would have loved a camera monitoring system. It may even be a good idea to have a simple security setup for an apartment.
These parts are designed to be used in a quadrocopter. They are sold as replacement parts to pre-built quadrocopters, but work well as interchangable parts. This is documention on the specs and how to use the parts, since none is really provided.
An IMU is something used to detect primarily orientation, but is a general term for an Inertial Measurement Unit. Needless to say, they can provide some vital information for mobile robots. In particular, flying robots need them since there is no way to guess orientation using wheel encoders.
I want to make a divergence meter. A divergence meter is not a real thing. It’s a fictional device from Steins;Gate to tell if the worldline (timeline) has changed substantially from an original world line (the alpha) - following the time travel theory popularized by John Titor. If you’ve never…
I could not really find any great Blender models of the Arduino Uno on the internet, so I decided to make my own. Mine was made entirely from scratch and does not use any image textures (except the wood in this demo). It features most of the details of the Uno, but does not have the printed circuitry. It was modelled off an image and some eyeballing for sizes, so it may not necessarily be to scale, but it looks close enough for Blender work. Even the text is there, using the default Blender font. The Arduino logo is actually a mesh of a circle. The most notable chips have the proper text on them, and the plugs even are shaped like sockets.
