It is amazing how many Arduino programmes for decoding rotary encoders start with something like: “I looked at all the available rotary encoder sketches and none of them met my needs, so I have ...

I would like to read the "Rotary Encoder with LED (Red) with Knob Set" available at Akizuki Denshi Tsusho using an ESP32. In two previous articles, I implemented this using polling and was able to ...

What is a rotary encoder? A rotary encoder looks like a potentiometer, but it is fundamentally different. A rotary encoder can rotate freely unlike a potentiometer and instead of variating resistance, ...

Here is a trick that allows you to connect one or more rotary encoders to a microcontroller while using only one (1) analog input. Here is a trick that allows you to connect one or more rotary ...

As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...

We’re digging these daisy-chainable encoders built by [fattore.saimon]. Each module consists of a rotary encoder attached to a PCB with a PIC16F15386 on the back. As we’ve covered in the past, the ...

Following our coverage of a 4.3-inch ESP32-S31 display development board, a Facebook reader pointed out the GUITION JC3636F118C-I-YR1 rotary encoder with a built-in 1.8-inch touchscreen display. It ...
