When I connect an input, the LEDs doesn’t form numbers but they light up randomly. I just want to know the right d561 to connect the output pins of to the pins of 7-segment display? Each segment on a 7-segment display is designated a letter A-G. This is standard and is shown in datawheet SN datasheet:. You can use a diode tester or a simple voltage source and a resistor to determine the pinout of your particular display.
Then just map the pins correctly again, from datasheet:.
Seven Segment Display
Note that this datasheet illustration is a bit messed up and the bottom segment is D not Eand next segment clockwise lower left is E.
The pinout is here:. Simply wire the respective letters a.
Pin 5 should go to GND. Note that this is an ancient display and an ancient TTL chip both are museum old and because it’s TTL open inputs will read as ‘high’. You need to tie them to appropriate logic levels RBI should be ‘0’ if you want to display a zero. Further, this really old chip saved a few transistors by not fully decoding inputs above 0x09, so 0x0A.
Like the other two most popular answers, your 7 segment display needs to be connected to the properly Outputs to Seven-segment display inputs: However, they don’t seem to mention that you need to have the inputs of the connected to something for it to work like you want it datasheeh.
