Knob Sketching

Build a fun sketch drawing toy using CircuitPython and 3D Printing. Powered by the Feather M4 and 2.4in TFT FeatherWing.

Draw letters and shapes to create your own artwork using knobs!

3D print a snap fit case to house all of the electronics!

Pixel Drawing

Use the two knobs to move a cursor up, down, left and right. The toggle switch lets you do a pen up and down so you can turn off drawing to make separate shapes. Use the button to clear the screen.

Easily customize the background and drawing colors using CircuitPython!
