battery / power question
August 19, 2008
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..
i´m looking for an advice in wich kind of batteries should i use!
I´m using one battery to power the arduino and other battery to power the motor shield (adafruit).. so i don´t know what to do ... :)
good power setups will also be welcome!! :)
thanks and best regards
