Hello, in my project, I will need to set 6 led switches to commute between modes.
I made the programation to switch between them and i works fine, but in my test I use the 5V output of th arduino DUE,
as is show in the example http://arduino.cc/es/tutorial/button, but I will use a TFT shield CTE35IPS, wich ocupe this 5V output.
What I should do? Should I use an external battery for the circuit? In that case, which resistance should I use?
There is anyway to use the power from arduino? Even divide that 5V output?
Thanks in advance!
