Was going to run the LED on 12V and determine the correct resistors to get the correct current
(in this device it is 80ma ) as my 7805 was only rated at 100ma
In the end I replaced the 7805 for a 1A version. The LCD already has the correct resistor fitted on board to connect to 5V. Found a 22Turn Trimmer for the contrast and that worked fine too.
Onwards and upwards...need to program the PIC soon if I can beg/borrow/make/buy a programmer
