I've been building the landing gear and Com1 examples with Teensy 2.0. Love playing with the coding and the hardware.
I got everything working but purchased some RGB LED's so I could have only one set of LED's instead of the yellow and the green ones in the sample.
I purchased Radio Shack's 276-0028 - "5mm High Brightness Full-Color LED". However, they did not work. Come to find out, they have a common anode. In testing, I have VCC -> Resistor -> common and then jump blue leg to GND and it works. Jump green leg to GND and it works. Same with the green leg.
So my question is, can I drop a teensy pin to ground to turn each one on? An easy solution is to find an RGB LED with a common cathode but I thought I'd check here first.
BTW, I am not an electronics type of guy and this is my first dive into hardware.
Thanks in advance.
