The ESP32 microcontroller has become a cornerstone of IoT development, thanks to its versatility and powerful features. One of the most crucial aspects of working with ESP32 is understanding its pin ...
ESP32 is a versatile microcontroller and a great starting point for anyone venturing into the IoT realm, but its configuration and interfacing of sensors can be challenging for new users. Arduino ...
If I pass 20, which is an ADC pin, into analogInputToDigitalPin(p) it would return -1 due to the first check as 20 is not less than NUM_ANALOG_INPUTS which is 20. If I pass 19, which is an ADC pin, ...
The Maker’s Pet Robotics Kit is a DIY learning kit designed for robotics enthusiasts, students, and hobbyists who want to explore autonomous navigation and mapping. At its core, the ESP32 works with ...
If you’re building a CNC or laser, there’s an excellent chance you’ll be using Grbl to get moving. It’s also a pretty safe bet you’d end up running it on some variation of the Arduino sitting in a ...
Hello, I’m excited to review the ESP32 display modules and HMI touchscreens from Elecrow with sizes ranging from 2.4 to 7.0 inches. For this review, Elecrow kindly provided me with both 3.5-inch and 7 ...
