If you are not using a 3.3V Arduino board, that Arduino will send 5V signals to the SI473X device through the digital pins and the I2C bus. That configuration can make the system unstable or damage ...

Makita batteries use a modified 1-Wire protocol at 5V logic levels. The ESP32-C3 operates at 3.3V and cannot reliably communicate with the battery directly. By splitting the system into two MCUs, each ...

Qualcomm, which purchased microcontroller board manufacturer Arduino last year, just announced a new single-board computer that marries AI with robotics. Called the Arduino Ventuno Q, it uses Qualcomm ...

There are plenty of drones (and other gadgets) you can buy online that use proprietary control protocols. Of course, reverse-engineering one of these protocols is a hacker community classic. Today, ...

The 8051 was an 8-bit Harvard-architecture microcontroller first put out by Intel in 1980.  They’ve since discontinued that ...

Tired of building the same old Arduino projects like blinking LEDs, temperature monitors, and line-following robots? Now it’s time for something fun. It’s time to turn your skills into entertainment ...
