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 :-)
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?
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 ?
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

Thanks for sharing this very well teaching information, am really honoured
Great job Sir Thanks v much...... Im sending you a suluat from Bahrain.... Peace ✌️🇧🇭
A great explaination! Thanks a ton!
Tku mann its too useful for mee....
This vedio make my viva bestt... 😍😍
It was really helpful. Great explaination
Very well explained. Thank you very much.
Omggggg thank you soooo much. Very well appreciated. Thank youu thank youu
Nice explanation, thanks.
this was great. you really helped me. thanks a lot
Very well explained! Thanks.
thank you man, really really useful!!!
Andito ka kasi Project nyuto.ahhahaha
Very good video.

Yeah or use a transistor
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
what does 74 represent in 74 ic circuit?
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
Hi this video may help: th-cam.com/video/wxjerCHCEMg/w-d-xo.html
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.
How about the A to F ?
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.
can i also use 74HC193
You can compare the datasheets to see if they are the same or not
I want change new pim no
my i ask how old are you sir
7447 is Bad 7 segmen display for nmr 6 and 9.
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.
you saved my ass
