Unlike other ESP Development Boards, the ESP32-CAM has no USB connector to connect it to a computer. This might be confusing for beginners when they try to program this development board for the first ...

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 Arduino ...

For the challenge, I wanted to send data from my computer's real serial port (RS232 9-pin connector). For that, I created an adaptor circuit because the voltages on a computer serial port are ...

In Arduino environment, it's convenient to access BT SPP like a serial port and react to the command string sent from the BT serial port. Many Arduino projects have utilized this way to allow remote ...

These days, connecting your microcontroller project to a WiFi network is pretty easy — you connect up an ESP8266 to your microcontroller project and pretend it’s a WiFi modem, using these ...
