please help. I'm new at this.

hi everybody. This I'd the first time I'm using a BS2 to control something. I'm trying to control a motor that only draws 1A. The circuit is done and I'm at the programming stage. My main power source is a 9 Volt battery. I installed a pushbutton on pin 8 as an input. I want the circuit to behave in a way where, when I press the button the time I hold the button is recorded into a variable. Thenthe controller will take this value and run my motor automatislly with the same duration I held the button. I was thinking of using a counter to record how long I held the button then decrement so the motor will run by itself. Any suggestions on how I should up about my little project? Thanks guys.

Hi liquid12341234. Nice to see some newcomers around the forums. However, this should be posted in the BS2 forum, not the Hydra forum. You'll find more people willing to help there.

It's also against forum rules to post the same question in more than one forum. Please don't. You are unlikely to get any better or faster answers.

Liquid, did you get your question answered? In a nutshell, you just need to use a digital I/O to control the base of a transistor, fet, or other high power gated device which in the secondary circuit will be your motor. Then counting is fine as you mention. Just make sure you look up some motor driving circuits, so you have the proper protection, etc. But, hopefully the BStamp people have already helped you out [noparse]:)[/noparse]

I would probably count by making a loop and the number of times is recorded like this:

time var word
length var word
sub:
if in1 = 1 then
gosub counter
else goto turnonmotor

counter:
time = time + 1
pause 5
gosub sub

' here I advise you to use the high command to turn on a transistor for your motor

turnonmotor:
length = time * 5
high 0
pause length
end

I hope this will work for you, and if I made a mistake, I'm really sorry. Hope it works for you. (p.s., incase you didn't notice, you need to put the name of the microcontroller and the pbasic version at the top)

Thanks for posting this routine

time var word
length var word
sub:
if in1 = 1 then
gosub counter
else goto turnonmotor

counter:
time = time + 1
pause 5
gosub sub

turnonmotor:
length = time * 5
high 0
pause length
end

I was thing of doing the same thing along the same line as what you want to but not to control a motor

When I press the button the time I hold the button is recorded into a variable. Then the controller will take this value and run my motor automatislly with the same duration I held the button.
