my first post here!!
i´m glad to find letsmakerobots!!!!!
i´m an electronics newbie, i´ve made my 1st robot wich i´ll post photos as soon as i find out how to create a blog entry :)
now, i´ve started a new project, wich is an offroad car, and i want to add brains (arduino) and some sensors (ultrasonic and infrared).
the first problem is, i´m using 9v batteries, and the steering motor seems to need more power, a noise comes out and it only moves a little..
