The two example knob sketcher toys in this guide work well enough to demonstrate the basic idea and have some fun. However, there are lots of other "features" that cold be added. Here are some ideas in no particular order.
- A pen up / pen down capability
- Add an eraser capability
-
COLORdisplay and control - Save / load display to file
- Different brushes
- Connect skipped pixels with a line
- Accelerometer to erase on shake (for old skool feel)
Try adding one or more of these features using the provided code as a starting point. Or add some other cool feature. Have fun!
We don't make mistakes, just happy little accidents.
