Limit Switches with arduino uno R3

It's a perfectly explicit schematic. What symbols did you not understand?

double bars
double bars with a slash through
shows 4 resistors as an H bridge i think with no rating, description, etc
i believe the other symbols are limit switches, don't know

Ken

double bars - NO contacts
double bars with a slash through - NC contacts

shows 4 resistors - no resistors are shown. You mean the diodes?

i believe the other symbols are limit switches, don't know - BINGO we have a winner

That is not in the circuit. That would happen under program control, by changing the relay state. Oh, shoot. I answered that one already...

Do you have two such circuits, Left & Right and UP & Down ?

What motor are you using ?

We really need to see a schematic as things are wired now.

What is being done A or B

What type of diode ,color ,shape etc.
These are the kind of things that a retired person needs to have explained. Basics!

Did you Google, "diode"?

I want to apologize to everyone for taking so log to get back to you. Lots of things to do this time of year and thank you for the help so far. You you have helped me understand some things.

Yes i did google "diode". Quite versatile

B-Simple dual axis

Simple dual axis in a frame

I don't have anything wired right now. This is from scratch.

Do you understand the schematic from post #25 ?


If you have dual axis, you will need 2 such circuits.

I think I do, other than the specs on the Diodes and possibly where to get them. I don't think I just ask for 4 diodes please??

A axis 1-2 out put pins arduino

B axis 3-4 out put pins arduino

Would that be correct?

For a low current type motor, a 1N4007 should suffice for the diodes, you will need
2 X 4 = 8 diodes.

Another alternative would be to use 2 diode bridges.

We need to know what motors you are using ?

You can use the Arduino pins D2 and D3 for the A axis; you can use D4 and D5 for the B axis.

If you are located greater than 45 degrees from North, there is not much point in trying to move the array vertically. The sun will always be close to maximum.

these are the 2 motors I am using
