Team Glen – Prototype I – addressing CPRF resident concern: Smart Mailbox

As you know the concern  we receive from one CPRF resident  during prototype I presentation, was to know whether there is a was to momentarily turn off the LED on the receive.

The reasons behind it were perhaps the user is sick, or the weather is not that clement outside. So he/she would like to have  a way to turn off the led for a short period of time.  

In the new code this can be done with the function “ledTimeOut”. After the timeout period expires normal LED activities will resume until mail are picked up from the box or the push button is pressed again. 

Below you can see the new code for the receiver:

Also below is a new connection diagram for the receiver which now includes the push button.
