Same problem.
They dont toggle. They switch back as soon as you let go the switch.
Also motor is not powered at all using your diagram. I had to rewire it.
1,6 needed ground and 3,4 12V. 2,5 motor the same.
Now for some reasons arduino nano is dead. It wont reset, it wont flash, it wont work.
Had to order new board.
My question now is: once i get new board, do i just flash it with firmware or i need bootloader 1st ?
I need some step by step for bootloader please.
You may be sinking too much current through the control pin. It is only good for about .25 amps at the most. The board may or may not come with a bootloader. They usually do but depending on the vendor and price there is a chance it may not. The text about on the vendors page should say, or you could just ask the vendor.
In that circuit the motors get power through relay but like you said the buttons have to be pressed to enable the ground for it to work. Again though the latching relays should solve that issue.
