🔥Multiplexers and demultiplexers are devices that allow us to control a greater number of devices with a smaller number of inputs or outputs. We can use these devices to expand the number of inputs and outputs of a processor like Ardunio.

I like these! And when an overlap of channels would/could be disastrous, you have a built in safety fail safe.

Wow, super explanation of a Multiplexer, I'm new to this term and it was fascinating to see one in use inyour channel. Thanks a lot!
@dellodel9502 Рік тому
You make great videos Thanks for the best explanation
@jorgeestefania3184 Рік тому
you can actually turn two leds at the same time if you divide the time and frequency for each led. For example you could change the output channel every 10 ms and you would see that (virtually) different leds are on. This can also work for demultiplexing
@eatthisvr6 8 місяців тому
Would that work for toggle switches or would they flicker ingame?😊

@siv_valentin Рік тому
Much simpler you can use charlieplexing on led part of optocouplers/SSRs , because it doesn't require an auxiliary ic for that task. For example with 3 i/o pins we can control up to 6 i/o devices, with 4 i/o ... up to 12 and so on. The basic formula for this is n*(n-1)=num of i/o, where n = num of i/o pins
@BenM0 Рік тому
@Electronoobs Thanks for sharing another awesome tutorial, that's very helpful for me. regarding your digital multimeter project, instead of using a bulky ssr why you didn't choose a small digital switch like LTC1477 ? i think that fits better in your small project's PCB.

You could have used a 74HC595 sipo shift register, it uses 3 control pins and gives you 8 digital outputs, but you can daisy chain them for as many digital outputs as you like while still using only 3 pins.
@laurv8370 Рік тому
Exactly my thoughts: use a shift register. Moreover, with a latch and output enable signals, you can also solve the issue about turning two (or more, or all) pins in the same time. But you lose the input ability hehe, I guess you can't have all.. 😛

Shift registers aren't instantaneous. Although it won't be important here.

Hi! Thank you for this presentation. Do you know a way to read or write to multiple I/Os at the same time. I have a project where I want to read multiple PWM signals at the same time using "analog" hall effect sensors. Thank you.

Sir can we use more than one outputs or inputs at a time? Please reply
@lasersbee Рік тому
5:44.. Since only one output can be controlled at a time you could have used a single current limiting resistor to ground for all the LEDs.
@Poult100 Рік тому
Thanks for making this video. I was going to use one of these MUX devices to increase the digital pins of my Nano but had not considered the limitation of only being able to address one pin at a time. I now may have to use a different MCU or maybe design a latching arrangement. Which would you suggest?
@slakjawnotsayin5451 Рік тому
I'm in the same boat, wondering if there is a simple and cheap alternative that would easily add more I/O's that aren't limited to only using 1 pin at a time. I have used the 74HC595 sipo shift register method as well, but wondering if there's another way like this MUX but better?

@PhG1961 Рік тому
Nice video !
@Davidlahall Рік тому
Great video...you used pwm and you said the response time of the MUX is in ns range...why not program it to select the to inputs or outputs you need at the fastest possible rate it can handle and simulate having two I/O on at the same time...more than likely you will never in this application need that fast response time. It's like pwm Led dimming to ours eyes it's dimming but it's really not.
@Rapptor22 4 місяці тому
You said you can switch on only one output at a time. Does this mean, that you can receive signal from only one input at a time?

I bought it brand new and it might inspire a cool series of vids that not really anyone is doing and I know the topic is right up your alley, the item was by no means cheap and it has to do with digital music.
