SMARS - 28BYJ-48

thingiverse

UPDATE: Corrected non-manifold and shaft hole error. The image displayed is the 3D printed corrected version. A remix of SMARS with a cheap 28BYJ-48 stepper motor, an idea from "cascadyas". It's a very inexpensive and easy-to-make robot/rover, the only challenging task being assembling the original track. The 28BYJ stepper is extremely slow, so please be aware that this robot will move very slowly. • M4 screw and nut (motor mount) • M3 screw and nut (slave wheel mount) Mounting the motor may require some effort; a long-nose pliers can hold the M4 bolt in place. A pinout diagram is taken from "https://www.arduinoecia.com.br/2014/07/motor-de-passo-28byj-48-motor-shield.html". "wtix" kindly provided information and code for the robot at "https://quackerlatuet.wordpress.com/2018/02/21/selbstgedruckter-roboter/", note that this is in German. "wtix" testing code for the robot using an ULN2003 driver can be found at "https://github.com/wtlx/smars-28byj-48". I have also tested SMARS - 28BYJ-48 and ESP12/E with the code from "https://www.thingiverse.com/thing:2312476". A video and files will be updated very soon.
