Tinman Electronics 7 - How to interface a quadrature output rotary encoder

Quadrature output may seem confusing at first, but when you get in there with the scope, and with Tinman's teaching on rotary encoders: you're bound to understand it!
You can find the circuit, arduino code, and other ressources I used for this video on my website: tinmanelectronics.com/articles...

Could you provide a link to those great breadboard probe point pillars?

First things first. Nice video. Explained nicely and clearly. On a side note, could you not make the same sort of thing using 2 photoresistors and 2 leds?

+Qbasic8 Thanks! And yeah, you can make a rotary encoder pretty easily, depending on what you have on hand!!

Use interrupts on 2 and 3 and then you don't use processing power. When interrupt then do A>B or B>A.......

Hi! Nice video, thanks for it. I was wondering, do you have a part number of your test terminals? I loved them, thanks again

@XanderBetts 7 жыл бұрын

Seconded. Those test terminals are rad. Took me a minute to figure out what they were when first seeing the circuit, but now I can't live without them!

The code seems MORE STABLE if I add a "b_last" in the condition : " if ((b == LOW) && (b_last == LOW)) " (Indeed you have to declare b before setup and b_last at the end of the loop.) Also, a 'delay(1)" exactly, at the end of the loop, seems to help accuracy

Thanks, I get it...

So, I tried this out for myself and I just don't understand why the resistors are needed.. I tried this with 2 LED's attached from 3,3 volts to pin 1 and 3. Attached pin 2 to GND and everything worked fine... Such a simple circuit as this seems to make the concept clearer from the start for noobs. (like me)

thought aload of BS - as got one of these - which looked up thedata - the actual code is 8-bit grey code - the four bit greyt is in the text - thereafter it gets to be less than computable . Recently got arduino - not played with , where count is easy - but conversion - can play with for a month of sundays - tedious . If bourns had published the conversion code from grey to hex , octal or binary in the increaseing from through binary - saveing a lot of errors , they have it as increaseing grey code

the program only counts in one direction. what could be the reason behind it?

@Xrispy24 8 жыл бұрын

+R Soni For me the program counted both ways. Did you wire this up yourself and test my code out?

@rsoni4992 8 жыл бұрын

+Justin St-Amant yes I did.... but it's counting in one dirrection only.

@rsoni4992 8 жыл бұрын

+Justin St-Amant I mean I did the connection as shown in the video, but counts only in one direction.

You must have forgotten to insert both of your count functions onto your code. U must have used them within your if statements such as: count-- and count++. If you only have one or the other it will obviously count in one direction only

Your information is very good,❤ I work with machines that use several encoders, and I loved your teaching, 🇧🇷😉👍congratulations on the video! 👏👏👏👏👏👏 "@arduinomaquinas" thanks you ! ( subscribed).
