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, ...

The value of a mirror is in its clarity. If the reflection is cast by [danicakostic17]’s Uncooperative Mirror though, you’ll find anything but. It’s described as a useless machine, because it appears ...

Rotary encoders connect to a shaft and, as the shaft rotates, the encoder outputs pulses. These are used to determine the speed of the object. By counting the amount of pulses per one full turn of the ...

Instead of sticking with the typical tabletop-scale builds, Arduino hobbyist and YouTuber UncleStem chose ...

So you've already outgrown Arduino's most beginner-friendly board, the Uno, and are looking to move on to bigger, more exciting projects. In that case, the Nano family might just be what you need.

You don't need to buy an SUV to get all-wheel drive. There are many sedans that offer AWD capability, and here we've ranked a variety of them from mainstream and luxury segments. Car and Driver's ...

I’ll just come out with it: I’m a travel writer, and I’m obsessed with wheeled luggage. Part of this stems from spending too many years dragging heavy, badly-designed bags around the world, resulting ...

People seem to be rather into the Unitree Go2 quadruped robot, if only for the low price tag. But perhaps more interesting ...

Linear measurement is fundamental to applications such as packaging, material handling, and converting. Even small discrepancies in speed, position, or distance can quickly lead to misaligned cuts, ...

This library uses a PCF8575 to read the pulses of a rotary encoder. As a PCF8575 has 16 lines up to 5 decoders with a switch can be read over I2C. The PCF interrupt line can be used to detect changes ...

Abstract: Combining camera, IMU and wheel encoder is a wise choice for car positioning because of the low cost and complementarity of the sensors. We propose a novel extended visual-inertial odometry ...
