Hello everyone again,
I am just wondering if anyone would be able to offer me some advice. I am trying to power a motor through the Bot Board II. The thing is the motor that I am using draws away 6V and a current which peaks at 150mA and then falls to 90mA. Because of the voltage it draws away, I am using an external power source of 6V to provide the power but would like the motor to still be toggled by the output of a pin on the Bot Board II. From what I assume, I will require some sort of switch, either a relay, transistor, or something along these lines but I think that relays appear to be for voltages higher than 6V therefore seems a little bit overkill. So basically what I am wondering is what would I use and what sort of specification should I look for to have a motor turn on and off depending on the control value of the pin on a Bot Board II?
Kindest Regards
John
A relay is best if you don’t need to vary the speed or direction. If you do need to change the direction or speed, then you’ll need a motor controller:

Thank you for your response. Will a relay be suitable even though the maximum voltage it will require is 6V? The ones Ive seen have capabilities to the order of 110V etc which is what made me think that it may be slightly excessive?
