The time returned by the NTP server is UTC time. To change the time, convert the UTC timestamp to the local timestamp. As MicroPython is a subset of Python, it does not have a direct function or method to conver
analogRead(analog_pin_number): We will use this function to read analog value. This analogRead function has only one argument which is a pin number of the analog channel you want to use. I have already provided pin mapping of all analog channels with GPIO pins above. So you will only pas...
2.How to Download MicroPython Firmware for ESP32 We have completed installation ofuPyCraft IDE. Next to program the ESP32 board we must flash the MicroPython firmware in the ESP32 board first. To download the firmware, go to theMicroPython download pageand search for the ESP32 firmware sectio...
Using a microSD card with the ESP32 is a great way to save data permanently. You can save big amounts of data intxtor in other formats—as much as the microSD card size allows you to. You can alsosave pictures if you’re using an ESP32-CAM. To interface a microSD card with the...
Description When using ESP32 and RP2040's UART for RS485 communication, how to handle the fast flipping of RE/DE pins, the different transmission speeds at different baud rates, how to know whether all data on UART has been sent, and how...
To place ESP8266 into the light sleep mode and later wake from the timer, use theespmodule or power-related functions of the machine module. This MicroPython script puts ESP8266 into a light sleep mode using theespmodule and blinks an LED, which is connected to the GPIO2, every time ESP...
Untitled ESP32-C3 board with 0.42″ OLED display Onboard display (the cutest thing ever): 72×40, I2C (SCL: 5, SDA: 6) Onboard LED: GPIO 8 Note: The display on this board seems to work better with Arduino IDE (select “ESP32C3 Dev Module”) rather than MicroPython. Use the u8g...
Note: At the time of this writing, the Bluetooth stack does not work with MicroPython on the ESP32 By default, the ESP32 Thing comes with the Arduino bootloader pre-installed. To get it to work with MicroPython, we will need to perform some extra steps. ...

Using regulated 3.3V voltage, connected to the 3.3V and GND pins. Be very careful with that: do not exceed the 3.3V limit, or your ESP32 module will be damaged. Attention: be very, very careful toonly use one of those options at the same time. ...
