im pretty new to arduino, so far iv'e experimented with the basics, LEDs, servos, analog inputs even the odd LCD display! proud of myself :smiley:. Now i want to move on to my first propper project, and i thought a simple robot would be fun.
for a drive system i thought continuous rotation servos would be easier to use than DC motors as i wouldent have to use a motor controller. and in terms of sensors im gona start with the sharp IR range sensors.

Q's:

  1. are continuous rotation servos compatable with the standard servo library?

  2. i looked at the spec sheets for the IR range finders, they say the output voltage is -0.3 to 0.3, this seemed kinda low to me, will i just be able to use the analogRed() function with this sensor? here is the spec sheet (i will post the link below)

all other sugestions will be apriciated!

thanks!

[1] yep standard library - the larger the position signal the faster it rotates.

[2] I haven't played with these sensors, but I think you are reading the datasheet worng - it's not a range of -0.3 to +0.3, it's a range of -0.3 to (Vsupply+0.3)

that would make more sence :stuck_out_tongue:
