I have attached my revised Arduino/Funduino board schematic. I have a number of servos attached to the Funduino as per the diagram, I use a 5vdc power supply and the servos are activated by the various switches putting (or removing) 5vdc on the switch pin.
As a result of a previous discussion here, I have overhauled all the wiring and ensured that all connections are tight, secure and correct voltages being supplied. All was well when I powered up the first time, now with no changes at all powering up on subsequent occasions results in servos activating and turning to the maximum possible position and staying there.
This has been observed even with out the ATMega328P chip being mounted.
I am at a loss to determine why and I don’t even know where to start with investigating, some help would be appreciated
