Notes:
Alternate parts sources. The electronic parts, such as resistors, diodes
And integrated circuits can also be purchased from
Mouser Electronics.
Breadboards can also be purchased from
Marlin P. Jones Association, Inc.
I purchased an additional clear breadboard for use as “show and tell”
when describing to the students h
ow the board works.
