but only for ESP32. Here in example pay attention to the end of the line - parameter ",false". To modify other examples just add ", false" as an additional parameter. AiEsp32RotaryEncoder ...

LILYGO TTGO T-Encoder, a round-shaped ESP32 board with a built-in rotary encoder, has gotten a shield with a 2-key keypad based on WCH CH552 8-bit microcontroller. Launched several months ago, the ...

We’re all familiar with getting feedback from a rotating shaft, for which we usually employ a potentiometer or encoder ... the synchro output, and an ESP32 dev board with a little OLED display ...

The remaining pull-up resistors are there for the SPI and interrupt lines. To interface the PMW3901 sensor module with ESP32, we use SPI communication. Since we had the Pimoroni PWM3901 module, we ...

Let's take a modular approach to sensor testing. The Sensor Evaluation Board was created to solve the hassle of repeatedly swapping sensors during development. Based on the ESP32-S3, it includes two ...

And you can find this sensor in many modern day ready made security systems. So in this article, we decided to interface the popular HC-SR501 with ESP32 and in the process, we will let you know all ...

LILYGO T-Encoder-Pro is a rotary encoder based on Espressif Systems ESP32-S3 WiFi and Bluetooth SoC, equipped with a 1.2-inch AMOLED with touchscreen support, and two Qwiic connectors for expansion.

In my series of articles about My journey into the Cloud I used the ESP32 Pico Kit hardware to send sensor measurement data to various cloud platforms. Using the same platform this review shows how ...
