you're a lifesaver, I was scratching my head when working on this 7 segment display of mine but then I realized that I placed my inputs wrong. Thank you so much for sharing this!
Your video has been online for a long time, but you helped me a lot with your explanation of the 7447. I realized that the clear definition (high or low) of the inputs is very important ;-) Thank you very much my friend, thumbs up :-)
One question, if i just put my current limiting resistor to the common anode/cathode of the 7 segment, instead of having a resistor for each of the segment (a to g) will that be alright?
Quick question, I'm New To EmbSys. So, I Am Trying To Use An Msp430 To display certain digits on 7seg. The msp430's Gpio pins output 3.3v. Would I Have To Step The GPIO output Volta pins up to 5V inorder To Get The Buffer To Work ?
Hi, your explanation was great, and i try to use this ic 7447 and 7seg Just like your video, but my 7seg doest work, can u tell me, whats wrong with my circuit?
Usually a 4 digit 7 segment display is connected is such a way that all 4 digits will display the same numbers. For example if your input is a 8, then all 4 display will show 8.

oh man thanks for the video event 6 years later you helped someone

Great job Sir Thanks v much...... Im sending you a suluat from Bahrain.... Peace ✌️🇧🇭
Thanks for sharing this very well teaching information, am really honoured
A great explaination! Thanks a ton!
It was really helpful. Great explaination
Tku mann its too useful for mee....
This vedio make my viva bestt... 😍😍
Omggggg thank you soooo much. Very well appreciated. Thank youu thank youu
Very well explained. Thank you very much.
this was great. you really helped me. thanks a lot
Very well explained! Thanks.
thank you man, really really useful!!!
Nice explanation, thanks.
Thank you so much ❤
In 2:10 you say that pins a b c d are gonna be left floating. What does that mean? Howdo the resistors help there? Sorry I'm a bit confused

Yeah or use a transistor

what does 74 represent in 74 ic circuit?
great video. Does pin 4, 5, and 6 have to be tied to +5V? Just wondering if it's necessary or not
Yes I believe you do have to make the connections in order for it to work correctly
How about the A to F ?
Is it necessary to use multiple 7447 chip when using a 4-digit seven segment display?
Also can I put both my RBO and RBI to ground when working with a 4 digit seven segment display? Thanks.
Usually a 4 digit 7 segment display is connected is such a way that all 4 digits will display the same numbers. For example if your input is a 8, then all 4 display will show 8.
Andito ka kasi Project nyuto.ahhahaha
can i also use 74HC193
You can compare the datasheets to see if they are the same or not
my i ask how old are you sir
hi, how do you get the decimal point (dp) on the 7 segment to lit up? Thanks
There is an eighth segment leg on the 7 Segment Display that will light up the decimal point. The BCD decoder does not have a pin to control this.
7447 is designed to be as common anode display driver and It will NOT work for common cathode 7-segment displays .
There is IC that can be configured to run both type of displays and that is CD4543.
I want change new pim no
7447 is Bad 7 segmen display for nmr 6 and 9.
you saved my ass
