Above you can see the circuit diagram for connections between ESP32 CAM and USB to the Serial Converter FTDI module. Suppose the SerialConveroter you use has options to switch between 3.3v and 5v. I ...

New code is in esp32_cube_enc folder. I changed sensor orientation. So, if you make my cube before, to use this code, you need to reprint one part. Battery: 3S1P LiPo (11.1V). Buzzer: any 5V active ...

Project idea: Well on an Arduino UNO if the sensor is connected to the Tx, Rx pin and it’s supply line with Uno’s 5V / 3.3V & ground pin and ... This is shown in the schematic. The ESP32 is a 3.3 volt ...

Wokwi is an online simulator for Arduino, Raspberry Pi Pico, and ESP32 boards, or even your own custom microcontroller board designed to learn programming without the actual hardware. My girlfriend’s ...

The very popular tandem ESP32 and Arduino IDE makes it especially easy to use FreeRTOS for task programming, as it is already integrated into the core libraries. In fact, you may have always used ...

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 ...
