Tanaka Masayuki's PCMFlow722 library enables (half-duplex) two-way real-time HD voice over ESP-NOW on ESP32 boards with a speaker and a microphone, ...

Arduino library for Adafruit Seesaw with a small footprint and easy to use. SeesawEncoder(uint8_t i2cAddr = ENCODER_I2C_ADDRESS, TwoWire &i2cPort = WIRE); i2caddr optional I2C Address of the encoder, ...

Stepper motors are a mainstay in precision control systems, valued for their simple open-loop operation and high torque at low speeds. Commonly found in CNC machines, 3D printers, and robotics, they ...

this is my $15,000 aircraft carrier it's very long and narrow which makes it kind of unstable on the roll axis especially in big waves even in smaller waves it has a tendency to Bob back and forth a ...

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.

This project focuses on PID-position-control experiments with Arduino. The HTML/JavaScript-based GUI enables easy optimization of the parameters. Since there are many articles on the internet about ...

Explore ham radio and Arduino in this video about “Arduino for Radio Applications” by Glenn Popiel, a must-have guide unlocking many possibilities. In this new video from Elektor, we bring together ...

Abstract: Electric motors are the most widely used actuators for converting electrical to mechanical energy. Stepper motors perform various automated tasks because their position control is accurate.

Adafruit has made an I2C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style) ...

If you want to get rich by hunting with a metal detector, you might want to consider how much you invested in the hardware to start with. Finding a tin can with a $200 detector might not make economic ...

Considering it's been almost impossible to buy a Raspberry Pi for about a year because of supply chain shortages, it's remarkable how many people continue to create interesting and increasingly useful ...
