I really admire the amount of effort you've put into creating this video regardless of how simple of a project Idea this is. To have done it perfectly and with proper aesthetics, gave the project much more value. Looking forward to more of your videos!

If you are not a programing teacher you should become one. Excellent step-by-step explanation, I will try it in my next project.

im addicted to your channel and decided this is my first ever arduino project..! ordered a leonardo, as im hoping to make a midi controller. got the display, board and pots .. WISH ME LUCK SENSEI!!💫

Value rounded to integer, will make potentiometer as an input keyboard, suited for combination lock. Function turning to max value, then decreasing to first pair and pausing 3 seconds will enter first pair combination, going to min value and then to second pair stepping 3 sec will enter second combination, then going to max value and back at pause will enter the 3rd combination, then turning to max value will open the lock. Good presentation well documented thks.

Thanks for sharing, very helpful!
I tried this on a teensy 3.2 using hardware SPI for the display and got around 125 FPS, very smooth!

This works great. built it very quickly. comment#1, the wowki page is great, but it shows it as I2c connection i guess...was a bit confusing to me but i am not very smart. i hooked to a cheap .96" oled screen that only had I2c connections. Middle pot pin to A0, sda to sda, scl to scl. Works perfect. And the cool unintended effect, my cheap oled is the type with the yellow on the top portion and blue below....the code worked out perfect where the dial part is all blue and the top indicater and "percentage box" is all yellow. Very cool. Can't wait to see more of your stuff. SUBSCRIBED.

Dang, you guys are so ahead of me! I guess we all really on our own journey 😎

Great content you have over here brother, keep it up.

Great video, I'm moving away from arduinio a bit but your video is brilliant, you gained a subscriber

[babaganoush]

This is awesome, I used the i2c connection on a Seeeduino Xiao. Took me all day but I got it eventually.

[dylanma]

I love it! I would make it into a volume knob. You should make a video on that. Also how much is the total cost for the knob and display.

[illygah]

more 1-bit animation lessons! that thing with the line at the end blew my mind more than I care to admit.... :D

[Im-HP]

The most detail explaination, subscribed

[milescarter]

Try a "precision potentiometer" "multi turn" or search 3590s potentiometer, would go very well with this display 👍🏻

[nikthefix]

One thing I always try to eliminate is the oscillation between adjacent values when the encoder is stationary but treading the line (especially with non-detent encoders). A 'demilitarized zone' either side of the current value which requires a legal reading of +/-2 is then valid but the counter shifts so not to lose steps. Maybe have a 9 bit counter divided by 2 to give 256 res to make it even more robust (for example).

[cuongnv]

We can cached sin(radians(angle)), -cos(radians(angle)) instead, then can reuse it for the line_x. line_y and text_x, text_y as well.

[naveengupta]

Very helpful just completed this project.

[jantube]

Nice tutorial! I have seen someone add a motor to a knob to create haptic resistance. Maybe that could be a mod for this project.
