Hi Doddy
thanks for above
decoupling caps never heard of but googled and think i know where to put them. I dont have any so onwards
the output of LM708 is between 3.8 and 5v ( just changes sometimes!!!!! )
regardless the button for cw produces an output around the battery input so i guess you could say that circuit is working
BUT i can get any power out of anything when i press CCW button even tried the switch on the other side of the l293 any nothing there either
Hsvr tried 3 different L293 ans 2 lm708 and the same happens
when i do have a static current of 5v to pin 16 the same results (cw works fine but ccw nothing
Am i wiring the l293 wrong?
looked at its data sheet and all seems correct in my brain ( not sure what inverting means
all i want is to have 2 buttons
1 to make 6v motor cw push another and ccw.
Is there a better module ? i only have 23mm max width of any piece so a whole aduno breadboard thing wont fit
just tried new Lm708 and when pin 16 is NOT connected i get a static 5v. as soon as wired to 16 drops to 3.8 ish seeems strange i have a 1.2v on pin 14 and or 11 like its bleeding power to these pins ( motor connections )
