You could have edited your original post you know. Even on an iPad.
Why are you using two Arduinos, ther is no need you are just making things more complicated for you. You have no way of sorting out what number corresponspds to servo with the code you have. You can do this in many ways. 1) send all the readings in a packet with a header and end of packet marker. 2) tag individual readings with a alpherbetic prefix 3) send the data as two hex bytes as each reading is only 10 bits, and use the empty bits to tag each byte with a unique bit pattern. 4) Best of all just use one arduino
You need to look at the transition of a button state not the level. So you compaire the button state with the paste state and only do something when the passed state was unpressed and the current state is pressed. Look at the state change example in the IDE examples menu.
Well if you are just asking if it can be done then sure that is no problem.
A few notes. If it were me I would use FETs instead of relays. It sounds like the discharge is going to have high current and relays being mechanical will ware out. Rather than pulse discharge the battries I would continuously discharge them. With pulse discharge you are giving the battery time to recover and that does not reflect a real life situation.
Looks like it to me. Either you missunderstand things or your language skills are not up to explaining the situation. That last post was nothing to do with " waves of power" what ever that means. An ADC measures voltage not power.
My intention was to use something like the circular pin sockets on many electronics devices, and provide the pins to the customer to put on wires. But I'm looking for a UK stockist and can't find anything.
Those are called DIN plugs and everyone has them, from Maplin to Farnell and everywhere in between.
