The Digital trainer kit we are using has 7 segment display, I wish to use it to realise the output for the 3 bit counter. How exactly can I use it? Where to give inputs?
I'm attaching the picture of what I'm trying to do. What are A,b,c,d in the display?

1\$\begingroup\$ It looks like it has converters built-in for converting binary to display patterns so just connect your counter outputs to A, B and C of one of the displays? \$\endgroup\$Finbarr– Finbarr2024年05月16日 10:02:10 +00:00Commented May 16, 2024 at 10:02

\$\begingroup\$ It's not displaying anything @Finbarr, I guess my circuit is wrong \$\endgroup\$user14822524– user148225242024年05月16日 10:21:19 +00:00Commented May 16, 2024 at 10:21

\$\begingroup\$ Maybe you need to get power to it somehow \$\endgroup\$Finbarr– Finbarr2024年05月16日 10:35:53 +00:00Commented May 16, 2024 at 10:35

It appears to be a BCD-input 7-segment display.
You apply logic inputs to ABCD pins. Examples:
A | B | C | D | Number |
---|---|---|---|---|
0 | 0 | 0 | 0 | 0 |
0 | 0 | 0 | 1 | 1 |
0 | 0 | 1 | 0 | 2 |
0 | 1 | 0 | 1 | 5 |
1 | 0 | 0 | 1 | 9 |
Could also be in the reversed order i.e. DCBA instead of ABCD.
