Best video on 7 segment display I've seen. Thanks, bro.

Life saving video bro
Best tutorial video I ever watched🥺😍

The next tutorial, can you teach how to control relay with tft touch screen and arduino with code please...

[DeanCArnold]

Great video. I would, however, like a bit of clarification. On your other video you calculate the resister value for each segment as 140Ω but in this video you say the value can be between 560Ω and 1kΩ. Why the difference? I'm asking because I plan to incorporate one of these using an ESP32 which can supply Vi at 3.3V. I want to make sure I get the calculations correct for the resistors (or may explore using a single resistor). Thanks.

great videos keep em coming pls do a set of tutorials

Can i use Arduino Nano with this lcd you're using along with touch module ttp223 ?

[geoffreyschuchardt]

Is the common anode missing from the diagram? I don't see it on the chart which heavily threw me off

[irfanahmed]

do u have any tutorial in which, there are 2 push buttons, if u press the first button number increases on display, and if u press the second button number decreases on display ?

[aarushikasundan]

Thank you so much you are such a lifesaver 😭🔥🔥🔥

[geoffreyschuchardt]

connecting the common anode disconnects the board

[austinfox]

Would it be possible to use this setup with an DS3231 RTC module so that time could be displayed on the 7 segment display? I'd like a circuit/code that flashes each digit of time for about half a second sequentially if an input button is pressed.

Hey just subscribed! i want to use this 7 segment display to count up everytime a photoresistor is at a certain value. Can you help?

[geoffreyschuchardt]

yeah your anode and cathode thing has me confused as fuck

[geoffreyschuchardt]

like why would I work on my code if I can't tell if the wiring is correct?
