As a newby I could not figure out how to make kiCad include the "vias" in the "pad" plot, and so I added them to the schematic, but they are not "significant" in that they don't represent actual ...

The Arduino's have strong enough pullups built in to the AVR chips that the I2C bus can usually function without additional pullups, BUT, the ESP32's pullups are too weak by them selves. So you need ...

Bojan Jurca’s open-source Arduino sketch "Esp32_oscilloscope," transforms any ESP32 board to function as a web-based oscilloscope accessible over WiFi. While the Scoppy project demonstrated the ...

So that may explain Wokwi ‘s popularity and it looks like a great platform for education with support for several Arduino boards (Uno, Mega, Nano), the Raspberry Pi Pico, and a generic ESP32 board ...

This weekend at the Bay Area Maker Faire, Arduino in conjunction with SiFive, a fabless provider of the Open Source RISC-V micros, introduced the Arduino Cinque. This is a board running one of the … ...

Programming ESP32 with Arduino IDE: STEP 1: Connect your ESP32 board to your computer through the micro-USB cable. Make sure the red LED goes high on the module to ensure power supply. STEP 2: Start ...

Arduino Core for ESP32 gets a Zigbee wrapper library Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been ...

If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Ardui… ...
