This document contains details about assignments involving using a CD4543 decoder chip and 7-segment display with an Arduino. It includes the student's name and details, hardware requirements, theory on how the CD4543 decoder works to convert BCD input to 7-segment output, and schematic diagrams. The assignments involve verifying the CD4543 functional table, setting up a circuit to convert BCD input to 7-segment display, and writing an Arduino sketch for an up counter that counts from 0 to 9 on the display.

ASSIGNMENT – 3(A)

Exercise 1 – To verify the functional table of CD4543

Hardware Required
▪ Decoder (CD4543)
▪ Seven Segment Display
▪ Single core connecting wires
▪ Tinkercad Software tool (https://www.tinkercad.com/)

Theory
The decoder (CD4543) is a combinational digital circuit that decodes an 4-bit binary input in the
range 0000-1001 (BCD) in to its corresponding decimal level. Example for the binary value 0101
we need to display 5. Hence the decoder will output a HIGH on segments (a, c, d, f and g) with output
a LOW on segments (b and e). The latch signal is normally connected to 5V via 10Kohm resistor as
per the circuit diagram. This allows the decoder to decode the present binary input (the latch is said
to be in a transparent state). When the latch is connected to 0V via the jumper provided its logic
state changes to a LOW and the decoder will decode the binary input prior to the latch going low
(i.e. the display is frozen when the latch is LOW).
