SMARS with modified 28BYJ-48
Description
This is a remix of SMARS with modified 28BYJ-48 stepping motors and USB rechargeable battery. The 28BYJ-48 stepper motors are modified to bipolar type for faster speed and to use with the Dual H Bridge Motor drivers with a higher motor supply voltage. The output of the battery charging integrated module is adjusted to 9V for the Arduino board and motors as shown in the circuit diagram. Space is a little bit tight, so take care for the cable and wiring. Using hot glue can be useful. Part list: - 1x Arduino UNO board - 2x 28BYJ-48 stepping motors (5V) - Adjustable step up lithium battery charging integrated module https://www.aliexpress.com/item/32998389598.html?spm=a2g0s.9042311.0.0.34e44c4dnylIg4 - 1x 503450 lithium-ion battery 3.7V 1000mah (size 50x34x5 mm) - 2x Dual H Bridge Motor driver https://www.aliexpress.com/item/32944408444.html?spm=a2g0s.9042311.0.0.bb094c4dPNtmON - 1x mini slide switch 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 https://www.youtube.com/watch?v=xWUmnuelc28 https://www.youtube.com/watch?v=B5uERrUn8mA
