Hi Dan,

Unfortunately ADC is input only; check out the Port Types section of our Hardware Turorials for more information at https://synthiam.com/Tutorials/Hardware.aspx

In order to have more than 20 ports you'd need to get another EZ-B.

Can't wait to see a robot that has so many ports

Thanks Cade C

Many thanks for the reply.

I thought that would probably be the case but thought i'd ask as i'm new to the device.

I'm controlling LEDs individually (1 LED per Digital Port). Is there any way to control more than 1 LED per digital port?

Thanks again

Since you can only get 5V out of a DO port you are limited as to how many LEDs can be run off a single port. I have an LED chaser circuit that is powered by a single port then I placed my LEDs randomly on the front of my bot so when it goes through the sequence they blink in random areas. But I am going to try and hook up to lower consumption(voltage wise) LEDs to one port and see if I can light them both (for my bots eyes).

Hi Bret

You could link 2 red LEDs in parallel and attach them to a single port. That would work ok.

This is a great site that explains LED circuits.

Another neat "trick" is to use a servo control instead of a digital control. The servo control acts like a dimmer switch for the LED.

Thanks Choyster

I'll give it a try.

Or use the pwm slider

Thanks for the suggestions guys. I'll try them out
