Description
Build a sketch drawing toy using CircuitPython and 3D Printing! Use the Feather M4 and 2.4in TFT FeatherWing to make a portable sketch drawing hand held device.
Use knobs to move the cursor and flip the toggle switch to pen up or down and use the button to clear the display. This uses Display IO in CircuitPython to draw pixels on the TFT display.
