Of course I'm goona use the relays, but I'll need the code anyway, won't I? The first thing you need to do is to think about how you are going to use those relays to give the forwards/reverse/stop control. Only once you know how the relays must be controlled can you write the code to do it! Manoj Sudarshan said:
I'm gonna use 4 combinations-specifying maybe 00 and 11 for motor off,01-forwards,10 backwards,or something like that This is entirely the wrong approach! You are putting the cart before the horse! First consider what you need to do with the relays, then map that onto port bit patterns |
