Nicely done. Appreciate you showing the detailed steps. It's great, too, IMHO that you show the wrong forks in the road that happen. Like trying to use the mm probes on the breadboard then switching to the wire. I believe those are important teaching moments for beginners.
Paul, I'm about 6 months new to electronics and a lot of videos for things on the internet are confusing or don't 'click' with me, or sometimes abstract the concept even more and make something simple seem much more complicated. Every time I'm trying to learn a certain concept and I come across a video by you, I'm immediately relieved because you are able to explain things directly, clearly, and precisely. Thanks for being a great teacher.
I watched you other rotary encoder video from about 3 years ago. I believe that you instruct at a good level, not too basic and generally not too advanced. Thanks Paul
it is another video about cows and calves, without any background or explanation of how things work. look boys, the light is working, we learn so much from this!
Can you explain why the 5v is required for this device? Rotary encoders not mounted on the small circuitboard as the one you’re using also can have five terminals but none of them are labeled +5v, so that’s got me confused. Thanks.
Hey Paul. Another good one. Keep the details coming. The information may not be relevant immediately but we are getting a great resource library to come back to in the future.
Awesome timing, In the decades of hobby electronics, I have never used one of these before, and I just happen to be working on a project that needs them, Thank you! awesome video as always.
I'll check out the videos in the description. But as a newer-to-electronics person I found the step through helpful. Never noticed the blue and red rails on the bread board referenced to power and ground. Definitely gets glossed over/people who teach this stuff get desensitized over time, I'm certain of that. Thanks
If you have an old Atari 2600 Driving controller you can use that for encoder experiments. It's not the paddles which have two per cable but the one that looks just like the paddle controllers except it only has one device per cable. Arcade machine games like Tempest and Missile command use optical encoders which are similar. The Missile command uses two of these for the x and the y direction for the track ball and the old style ball mouses also use optical encoders. Essentially the same thing going on...the direction is determined by which pulse arrives first.
Quick question, I hate debouncing in software, it is a hardware problem :), and with buttons will use a combination of a couple resistors, a cap and a 74HC14 to get clean switch signals, do you think this technique will work for the clk and dt pins? I ask as I am concerned about speed.
I have a few micro stepper motors and I was wondering how to control them with a micro controller? I have seen a video that says you can control them without a driver but I thought that could damage your chip. And you need to use a diode. Also can you control them from a small chip ? Like ATtiny85
Two resistors allow you to make a potential divider, where the voltage across one resistor is some where between the voltage placed across the two resistors. Look up resistor potential dividers for more information. just using resistors it is impossible to multiply or increase a voltage. my the very nature of resistors, they consume power not generate it.
I’ve got some cheap incremental encoders that bounce something fierce. Trying to sample multiple times to detect a state change is useless; too much bouncing; it doesn’t stay stable long enough. I have to detect the initial edge, then just ignore the pin for a while. Just increment or decrement from an interrupt routine is useless because of the bouncing. Even a capacitor has a tough time smoothing it enough. I know: I need to buy better parts. 🙄
Oh yeah . . . when the volume control goes tits-up on your Home A/V 28 channel super-duper unit . . . good luck DIY repairing. Down With Digital . . . Long Live Analog. Digital isn't all bad but there are drawbacks. Just an old school fuddy-duddy's opinion. Like your channel so far.
Don't have a RE, I got around that by using a pot and checking various voltage ranges in software to advance or retract a counter. Poor man's version? Lol.
*I have one of these. I always wondered how they worked. Thanks for this video*

I've never come across a rotary encoder, so I learnt something today.
it is another video about cows and calves, without any background or explanation of how things work. look boys, the light is working, we learn so much from this!
I explained exactly how it works. If you can't grasp the material, I don't know what to tell you.

Excellent this is the first video I have learnt about rotary encodes. Please make a video including the denouncing ZS5X

Thanks for taking the time to explain how a rotary encoder works Paul, I have learned a lot from your channel 👍😎

Really love the quality of your recent videos 100k roll on😊👍
I wish these modules came with datasheets.
I watch your channel it's great.
Helpful video 👍
Great video, I finally know how one of those things works. Thanks Paul..
I always wondered what the best size wire for probes.
What does everyone use.
Great Video as always.
I like the details for beginners like me. Thank you.
Very useful. Thank you !!
Very good video. Thx!
Newb here. Thanks for the clean explanation.
Is there a way to change the encoder to 2 push buttons instead, one click is CW and one click is CCW ???
Hi, do you thinks it's possible to connect two of these encoders in pararel? Thank you
Could you show us how to de-bounce?

Trimpots too.. we can get exact! X3

Use a hex contact CMOS debouncer IC. MC14490
There's some really junk rotary encoders out there.......

Hello
Im goin to probe my girlfriend 🤔
