Thanks Fratello,

i havent test with any transistor, because normally it works with an indication of LED. The ports can handle 100mA. I thought that would work like that.

This week i will be in Vienna and then i will be in America for some Seminars. So i wont be able to test in my lab the code or a circuit.

I will get 3 uLED 3,2 touch from Sparkfun and i will try to make and complete the circuit for RFID that i have started in addition to codelock circuit.
