Now the reason that it worked for you when you took out that extra and statement about the button_delay is because of my previous error.
What is supposed to happen is that you press the button, it loads up a variable with the number 50. then it wont let you press a button again untill that variable has gone all the way back to 0 again. but because I was using the incorrect variable name, I was never actually decrementing this variable which therefor meant it would never get to 0 and you could never inc or dec the speed.
so if you ow use the above fixed code, it should work much better
Now that you have explained to me how it works I can see the mistake hehe!, I was checking my breadboard and switches thinking I must have something wired wrong and then sat there and could'nt work it out haha.. so i just deleted the bit of code in the end!!
but its a cool bit of code to learn and mess around with
I like the bit of code toggle(LED)
thats a great command
Brad is there a tutorial about swordfish basic apart from looking on digital.diy? like all the commands you can use and what they do or mean?.
