Minor Project Revisited - a Report on failure

The Fritzing breadboard diagram differs slightly from my original.

I wondered why the EEPROM kept churning out readings regardless of whether or not the button switch was pushed - but i'd had this quick-&-dirty idea for having a LED come on when it was pushed; the on-board LED actually, which (Of Course!!) connects digital-pin 13 to Ground through the LED itself & its dropping resistor - Duh!!
Its voltage level's always going to be sagging towards Ground i.e. 0, never maintaining the level 1 needed to stop it from spitting out its data!
Connecting the button to digital pin 12 (as in Lewis Loflin's original!) fixed that problem.

Another difference is in the addressing.
My original breadboard had 2 24LC08 external EEPROMs effectively connected to the same address - writing to them may not have been a problem but reading would certainly have produced a clash (& a crash, most likely).
I2C chips have addresses of the form B1010ijk, where i,j,k=1 or 0, & each chip on a common two-wire interface requires a unique address for that interface, e.g. B1010000, B1010001, etc. The Breadboard above shows the 2 24LC08s set with 2 different addresses (achieved using pins A0, A1, A2) - see diagram.


More seriously, i couldn't get the program to produce a meaningful output on the Serial Monitor. The peculiar symbols that appeared do not appear in the ASCII table, & i've seen them before - in (deliberately) garbled transmissions in an earlier Task. The program would try to retrieve the specified number of bytes, but they were garbled.. I suspect my electronically-grubby fingers were at fault there, & that i've killed the chips (i had a spare, & karked that one also).

So, all-in-all, not a successful result.
