I am starting to build a robot, and have fallen at the first hurdle... I cannot get my PIC controller to work under correct battery power.
I have the PIC outputting servo control signals. I can monitor these with my oscilliscope.
It works when i hook it up to my benchtop powersupply, it works when i hook my 9.6V Ni-Cd power pack up directly (i dont leave it like that for too long). It doesnt work, however, when i power it by the battery, but through a 5V voltage regulator. I know that 9.6V to 5V is a bit silly and will mean a lot of heat output in the regulator, but it is a very temporary solution, and it should work ( at least in my mind).
I have measure the voltage difference across the Vss and Vdd on the PIC and they are 5V. The regulator is outputting 5v correctly. I have no servos wired in yet, so it isnt electrical interference.
Any help would be great.
