Introduce a DIY Arduino Drawing Robot
Recently, we produced a very early creator project - DIY Arduino Drawing Robot. In this project, I optimized the design of a relatively simple scheme for stepper motors and pen holders. The main control uses Arduino UNO R3, two motors and two servos, easy wiring, no driver, no welding, simple program easy DIY, the winding frame on both sides can be pasted on any wall to draw the pattern you want.
