This project is built on an STM32 microcontroller (tested with STM32F407VG), where a rotary encoder is used to control a counter. The counter value is displayed on an ILI9341 TFT LCD screen via SPI.

Below is a simple code you can use to read rotary encoder values with an STM32 Microcontroller. The example below is for a Rotary Encoder that controls how fast an LED blinks. The full tutorial video ...

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 ...

Abstract: In this paper, a single rotary inverted pendulum system is set up by using rotary encoder, servo motor and some mechanical structures. Lagrange equation is used to build up the mathematic ...

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

When it comes to design decisions, we’re often advised to “think outside the box.” It’s generally good advice, if a bit abstract — it could really mean anything. But it appears that someone took it ...

Abstract: This article introduces a low-power spintronic rotary encoder capable of 8-bit analog-to-digital conversion. The proposed encoder leverages spin-Hall effect-driven domain wall motion ...

Last year, we featured the T-Keyboard-S3, a USB mechanical keyboard with ESP32-S3, and four mechanical keys each fitted with a 0.85-inch color display. The upgraded T-Keyboard-S3-Pro adds a rotary ...
