You can watch a YouTube video to get an idea of the project: https://youtu.be/aJjqQPRCP54. To build this robotic arm, you will need two Stepper Motor DC 5V 28BYJ-48+ULN2003 Stepper Motor Driver Modules for Arduino. You can purchase them on eBay at: https://www.ebay.com/itm/Stepper-Motor-DC-5V-28BYJ-48-ULN2003-Stepper-Motor-Driver-Module-for-Arduino-HP/263100711657?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649. Additionally, you will need a deep groove rubber shielded ball bearing. You can purchase one on eBay at: https://www.ebay.com/itm/1PCS-6001-2RS-6001RS-Deep-Groove-Rubber-Shielded-Ball-Bearing-12mm-28mm-8mm/261497880518?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D44040%26meid%3D87fddd7d49a14dcdad96cfca60445817%26pid%3D100005%26rk%3D5%26rkt%3D6%26sd%3D272281636200%26itm%3D261497880518&_trksid=p2047675.c100005.m1851. You will also need some black electrical tape to secure the main shaft in place.
