Hello Can anyone help im new to PIC chips and this forum hoping i will find answer as referred here by Tech Support from Picaxe. Im having erratic behaviour with 14m2 when using v2, driving 2 motors via l293. When 3.7v battery used on v2 all is ok , however any higher voltages used ie 7.2v battery pack then i get motors continuing on and program erratic.
I have directly linked 14m2 to l293d no external components except 2 104
caps across motors and 22k and 10k for 14m2. Outputs from 14m2 direct to
l293 input and output from l293 driving 2 motors a & b, am i getting voltage spikes causing program to jump and should outputs from 14m2included inline resistors?? I hope this makes sense I have a pixace boardaxe020and wanted to make my own circuits smaller, noticed additional components on board, can anyone make sense.
Thanks Arif
