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.
Hi, the calculation should be correct and it is exact. But higher values can work except it will dim the dispaly. So get datasheet for your display and calculate it as shown in the other video.
@@robojax Can you please tell me what battery source should I use with arduino nano, touch module ttp223, reset button , 1 digit 7 segment lcd. Thanks alot !!
The most powerful item of yours is the seven segment display. For nano you can connect 7 yob12 at VIn pin so get a 9v battery which will run out fast. Best option is to use rechargeable battery .
@@robojax Thank you for helping out. Sir, if 7 seg display is power hungry. Can you please suggest me what will be the good 1 digit LCD that will require less power with all the devices mentioned above. I want this project to be cheap and portable with battery source. Can I power Arduino with 3 triple AAA batteries?
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.
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 ?
Thank you. I have a video on counter, perhaps you can use that and combine both to display number on the seven segment display ua-cam.com/video/zJ-yd4vYn8s/v-deo.html
videos have description below the video. there are links to the resources. Besides, I have shown the word "robojax.com" multipel times, just got to Robojax.com and get the code als well.
I’m appreciative for the tutorial but you start with an example of what NOT to do. Then go into the way to do everything. I broke my arduino because I accidentally shorted it and had to go get another one. None of that is your fault but from my standpoint the video goes from being unclear which method is which. I was originally under the impression that the resistor method was a separate one all together and the first example you gave was for common cathodes if the method with multiple resistors was for common anodes. Also some not on what resistors to use and why would be extremelyyy helpful. Because these videos I’m sure are made for beginners, and to us, this led display is a black box with inputs and outputs, but we know very little about the currents. I don’t think I’m alone in this. If you use one resistor instead of multiple, does it need to be greater? I’m assuming so but I’m unsure of how the resistance would compound in this situation. And this matters so I don’t short another board. And then suddenly it’s in another configuration where the diode isn’t on a board at all. Again, I’m appreciative but it’s a huge lack of consistency. When multiple things change in a system at once, people unfamiliar with that system will have a hard time figuring out the dependent variable from the independent outcomes which can significantly halt learning. And then it jumped right into the code section. Im sure it’s just because I’m new but those are some of my very real concrete beginner questions that contribute to the majority of my frustration. Although you’re doing an amazing thing by sharing what you know with people and I don’t mean to discourage you from ever ever doing that. Im just frustrated it’s day two of this, and I’m much more hesitant than day one because I’ll have to get another board if I mess up the single resistor I’m using and I’m only using 1 so my other resistors don’t touch and accidentally cause a short. Just because I simply haven’t learned these things yet.
Hi, it seems still you have not watch and listend. The seven segment needs different amount of current for each digit. for example (this sucks to type it as I have already explained it in video. why should I type it). digit 1 need two segments. digit 3 needs 5 segments. so when you used ONE resistor which is totallyh wrong and that is for lazy people. Because they are lazy, they get the lazy result. when digit 1 is displayed it would be very bright because two segments are turned ON and when displaying didgit 3, five segments are turned ON and the the display need lots of current. the resitor reduces the voltage significally (V=IxR ohm's law) and as a resutl the displayh will be twice dimmer. so please please watch again carefully. I have mentioned.
Best video on 7 segment display I've seen. Thanks, bro.
Thank you so much all the best sir.
Life saving video bro
Best tutorial video I ever watched🥺😍
I am very pleased you found it useful. Stay safe. Greetings from Canada.
@@robojax Love from India bro.
Good video, thanks for the tutorial
Great video thank u.🙂
You are welcome.
The next tutorial, can you teach how to control relay with tft touch screen and arduino with code please...
Oh god, thank you for the tutorial 😭
You are welcome. Please subscribe as this help my Channel to grow. Thanks
@@robojax sure!! Thanks for the help again

god bless you
God bless you too.
Can i use Arduino Nano with this lcd you're using along with touch module ttp223 ?
any arduino

Can I power Arduino with 3 triple AAA batteries?
No you can. Aaa has 1.5v then 1.5x3=4.5v and it will not work

I believe I have a video on that. Please search my channel. Here is how to find Specific UA-cam Video in a channel bit.ly/findUA-camVideo
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 ?
wow, interesting project but I don't have .
Is the common anode missing from the diagram? I don't see it on the chart which heavily threw me off
Good
Very nicely done.
Thank you. I am sorry for late reply. I was on vacation.
@@robojax no worries. I know how busy we can get. Thanks for the love!
great videos keep em coming pls do a set of tutorials
thanks. sure I will make more. here is the 2 digits ua-cam.com/video/k-f6lwwUTAs/v-deo.html and here clock ua-cam.com/video/qB0drI56zGE/v-deo.html

Can you Traslate it into Arabic

Follow this instruction snipboard.io/x80ryg.jpg
connecting the common anode disconnects the board
yeah your anode and cathode thing has me confused as fuck
like why would I work on my code if I can't tell if the wiring is correct?
Please watch carefully. I have explained it fully
