i recieved my motor controller yesterday and i am so lost. i already had the board of education and i was wondering if anyone knew of a good tutorial i could see to get the hang of the motor controller. or if anyone had a simple·pic of how to set it up or anything really that would be great. i just need any help to get started. thanks

NsanecomX,

There is a document availble online that could help with connections and sample code at the end of the document. This should get you up and running relatively quickly; if you have a specific question feel free to ask and I will do what I can to help. The picture of the connection and sample code are in the PDF below.

thanks for the link. im pretty unexperienced with the bs2 also. do i need more than one power supply for everything because all i have is the 9v for the bs2?

the .pdf·says to connect to the motor supply and the logic supply. how do i do that?

how would you suggest me setting up 2 motors on the board of education with the motor controller so that i could mess with it to get the hang of it. i think i could figure out the coding, i just dont want to mess the motor controller by setting it up wrong

thanks again

NsanecomX,

Commonly you would want to power the motors and microcontroller from separate supplies, as running motors will inherently muddle the supply line with noise; which can cause issues with the controller. The logic supply is the voltage that the microcontroller is running at, so for the BS2 it would be 5VDC (vdd).

ok that makes sense. would i just plug the new power supply into the bread board along with everything else?

is there a picture of the motor controller connected to the board of education that i could use to set up everything so i could mess with it and to get the hang of it? i dont want to chance hooking anything up wrong and ruining any of the chips
