I am having trouble connecting my arduino to a MD49 board in order to spin higher powered motors. I don't really have an idea on how to connect them physically yet. Then the coding is difficult too because I'm not sure what pin or subject to send commands to. I'm not sure what commands to send either. Is it still digitalWrite (___, HIGH) or something different for the MD49 board? Someone please help.
How much effort did you put into your research?
I found Arduino Examples after less than one minute Google search. I will leave the link for you to figure out.
I've been on that website more than once but that particular setup and everything didn't work. I tried it at least 5 times and the code can't upload to the board.
