Homemade Augmented Microcontroller
« on: April 28, 2011, 12:53:58 PM »
Ok, so in the picture below ( I got from SoR) it shows that the servo gets conntected in the 5v regulated slots? Isnt it just supposed to be plugged into the unregulated 6v slots? Or am I wrong and its plugged into the 6v?

Not sure which it is plugged into, but I assume you want to know if a servo needs a regulated power source.  It does not need a regulated power source, although if your unregulated power source voltage (e.g. 12 volts, etc) was too high then connecting to a regulated power source would give you an appropriate voltage.

Well my servo is limited to 6v max so Im using a 6v battery, just wondering how you would get it plugged into the unregulated without having to use the 5v regulated

The picture shows the servo attached to what should be the 6V bus. The bus on the side with the programming header should be 5V as those pins are ADC inputs.

Check the specs for your servo.  They usually run from anything between 4.5V to 6V.  And they'll state the response time.  The higher voltage will respond faster.

Also check the specs of your supplies to see that they can supply the servo with enough current.  I haven't tried, but I doubt you could run a servo from a 100mA regulator.

The control signal is just logic level.

What about http://www.robotshop.com/dfrobot-romeo-all-in-one-microcontroller-atmega-328-4.html is that a pretty good starter microcontroller? would it be able to run 2 servo and some sensors?

Yes, but even a $2 PIC can run several servos plus sensors.

Do you think you can link me a simle easy starter MC? I am really confused on the programming part...and on where everything plugs in....
