SMARS with modified 28BYJ-48

thingiverse

This is a remix of SMARS with modified 28BYJ-48 stepping motors and USB rechargeable battery. The 28BYJ-48 stepper motors are transformed into bipolar type for faster speed and compatibility with Dual H Bridge Motor drivers requiring higher motor supply voltage. The output of the battery charging integrated module is adjusted to 9V for optimal operation of the Arduino board and motors, as clearly depicted in the circuit diagram. Space constraints demand careful cable and wiring management. Hot glue can be a valuable asset in keeping everything tidy. Required components include: - One Arduino UNO board - Two 28BYJ-48 stepping motors (5V) - An adjustable step-up lithium battery charging integrated module available at https://www.aliexpress.com/item/32998389598.html?spm=a2g0s.9042311.0.0.34e44c4dnylIg4 - One 503450 lithium-ion battery with specifications: 3.7V, 1000mAh, dimensions 50x34x5 mm - Two Dual H Bridge Motor drivers available at https://www.aliexpress.com/item/32944408444.html?spm=a2g0s.9042311.0.0.bb094c4dPNtmON - One mini slide switch available at https://www.aliexpress.com/item/32859663187.html?spm=2114.search0604.3.14.349c7461npBSca&s=p&ws_ab_test=searchweb0_0%2Csearchweb201602_7_10065_10068_319_10059_10884_317_10887_10696_321_322_10084_453_10083_454_10103_10618_10307_537_536%2Csearchweb201603_53%2CppcSwitch_0&algo_expid=be07d9b5-bf68-401c-9225-568a880b562b-2&algo_pvid=be07d9b5-bf68-401c-9225-568a880b562b Further information and visual guidance are available at the following YouTube links: https://www.youtube.com/watch?v=xWUmnuelc28 and https://www.youtube.com/watch?v=B5uERrUn8mA.
