Project #440
OBJECTIVE: Use the Alarm IC as a switch to flash the letters
“C & E”.
Use the circuit in project 435. Connect A, D, E, & F to the circuit. Turn
on the switch (S1) and the capital letter “C” should be flashing. Now,
connect A, D, E, F, & G to flash the capital letter “E”.
Flashing “C & E”
