The address change is now interactive: you can scan the I2C bus and change the address of each modifiable modulino.
All of this can be repeated without having to recompile the sketch and upload it to the board.

This is an example of output provided by the sketch on the serial:

ADDR	MODULINO	PINSTRAP	DEFAULT ADDR
0x1E Buzzer 0x3C 0x1E 
0x36 Smartleds 0x6C 0x36 
0x37 Smartleds 0x6C 0x36 * 
0x38 Smartleds 0x6C 0x36 * 
0x3C Encoder 0x74 0x3A * 
0x3E Buttons 0x7C 0x3E 
0x50 Smartleds 0x6C 0x36 * 
0x66 Buttons 0x7C 0x3E * 
0x77 Smartleds 0x6C 0x36 * 
Enter the current address, space, and new address (ex. "0x20 0x30" or "20 2A"):
 - Enter "<addr> 0" to reset the device at <addr> to its default address.
 - Enter "0 0" to reset all devices to the default address.

devices are recognized either by their (fixed) address or by sending a message and reading the pinstrap result
for each device it will also show if the current address has been changed from the default
allows to reset the address of a device (or all of them) to the default, by setting the requested address to zero
