LED-Wiz and Breadboard Question

yotsuya:

Thanks, scream! Just one more question- you state to connect the ground from the board to the ground on the LED-Wiz. But when I look at the diagram from the handout that comes with the device (I have the older version, btw):



It doesn't have anything going to the ground. I would be powering this via the USB power from the LED-Wiz, not an external source. Do I only need to hook up the ground if I am using an external source? Thanks!

scream1973:

Sorry you are correct. Since you are not using external power you would not require the ground connection.
I am using the 5 volt from externally so the ground was required..


yotsuya:

You have been a great help, man! I appreciate your assistance! I'm going to go get the breadboard after work so I can get started.  :cheers:

Glad to be of help... Just remember if you are using raw leds to put resistors in line as well so you don't release the magic smoke..
