    I have a setup that uses 2 x 18650 3.7V 4000Mah batteries in series ( producing 7.8Vdc. Im trying to control a 6-9V dc miniature motor with 2 buttons 1 button to CW and the other to CCW
    Ive been told that a L293d will work but ive blown up 5 so far
    I think the problem is im imputing too high a current into the Vcc1 (pin 16) which calls for 5V (max 7) attached is a diagram i found with basic setup I would appreciate someone confirming the setup IF I REDUCE INPUT TO 5VDC
    Also if i connected something to the end of the + 7.8v feed to reduce the current to 5V .
    Im not electronics savvy so appreciate any help
    Thanks Richard
