IRF510 Mosfet on the B.O.E.
I want to set up one mosfet to drive a motor both ways ie
Red = +
Black = -
Black = +
Red = -
is this possible with the Mosfet or do i need two mosfets? looking at an RC car there is only on mosfet and its driving it to do both ways... are there any tutorials such as using PWM on it and running with the mosfet? thanks

there is the mosfet, there is a Giant motor for the front and back which in in the rear and another motor which is left and right in the front... i was to take the relays out and use this stuff on my board so that i can mak this car roam on its own with no help from me do you mind if i PM you for furter investigation?
. . .

thats what it looks like i guess that data sheet really doesnt help.... anyways ill try to figure it out if you dont reply again! thanks pk

10A switching capability.
~ SPST-NO configuration.
~ Small footprint.
~ Sealed version available
thats waht it says.... its a single pol single throw? how can that be possible....
im getting the feeling there is somthing else running the other motor? there are two of these relays and 2 motors... you guys are saying i need 2 relays for one motor to function the way this thing is operating...
also how can i switch these from the MC? the coils goto the pins? that way i do HIGH LOW, LOW HIGH and it switches the pins?
*edit*
theres no logical way it could be a Single Throw Single Pole... even looking at the mother board it shows a single pole and two lines· which it pivots from, this datasheet must be incorrect..

DO
PWM 13,255,255
PAUSE 500
HIGH 15
PAUSE 1000
LOW 15
LOOP
but it doesnt do anything? any suggestions would be used greatly...!
correction** they are making a humming noise it kinda scared me so i took out the battery...

here is the DPDT

will these work before i buy them?
would one of you possibly be able to answer this... this motor is huge and i connect a 9 volt battery to it and it didnt move but i connected the 7.2 volt rechargable it came with to it and it ran.....im a little confused on that part? thats eliminating the idea ^ up there because i was planning on running it off that 9 volt but it doesnt run!

when i touch the wire in the pin it shuts the board down...
VDD->Relay<-VSS
that works^
p15->Relay<-VSS
this does not when i use
DO
HIGH 15
LOOP
it doesnt shut the board down if i leave the wire in there only when i pull it out fast?

i looked it up on google and i seen this thing that i had taken off with looks like a salt block it says 1 ohm on it?
5W0.1OhmJ
thats what it says and it looks like a salt block... you can see them in the attachment below

i found that which is exactly what i need to do besides speed... i might decide to ramp it eventually but thats exactly what i want to do... i wont go with relays if they are that much trouble but my question is will i be able to use an HBRIDGE to control both motors seperatly? what are your ideas on controlling a steering motor and the driving motor, i dont have to use the stamp to physically control the motors... just control the currect from the battery it comes with.? any ideas would be great..
