TkInter GUIs can get extremely long very quick. Fortunately they can be split into multiple files - especially if you give them a class wrapper. The important thing is that you pass the relavent parent elements so more widgets can be inserted into the frame or window. The below example shows how…
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.
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…
Angstrom Linux is what ships on the BeagleBones. It’s kind of terrible because I think everyone when they first get it will say, oh I should run opkg upgrade so that everything is up to date. Guess what? That breaks the boot. It won’t startup anymore. I don’t know how to fix it or what goes…
The BeagleBone is like a combination between a microcontroller (like Arduino) and a small Linux desktop. It is most similar to a Raspberry Pi, but with more pinouts and a faster processor. The BeagleBone has several variants, the most recent edition being the BeagleBone Black (aka BBB), which…
The BeagleBone Black is a very powerful and affordable microcontroller - superior to an Arduino Uno in a lot of ways. It’s fast enough to be used as a desktop computer, yet it has more pinouts than an Uno. With the BeagleBone Black priced at $45, it’s really a great value compared to an Arduino…
To use Python as a graphical interface for an Arduino powered robot, programmatically read the USB with the pySerial library. However, waiting for input from pySerial’s Serial object is blocking, which means that it will prevent your GUI from being responsive. The process cannot update buttons…
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.
So, you want a GUI for your robot. Sure, you could make a nice GUI in Python with Tkinter, but there are some really good reasons to try it as a website instead:
It is one thing to make a GUI and another to make a GUI that people will want to use. Despite the fact that the appearance of a GUI does not really affect how the program runs, it is always prudent to set up GUIs in a way that they could be presented professionally.
