ESP32 is a smart microcontroller board with built-in Wi-Fi and Bluetooth capabilities. ESP32 comes with an internal RTC, but its working is dependent on power. So if you want to design projects or circuits that you want to run even when there is no power, you must use any external RTC...
You can use the preceding links or go directly to MakerAdvisor.com/tools to find all the parts for your projects at the best price!SchematicWire the DS1307 RTC module to the Arduino and the LED, as shown in the schematic below.You can also refer to the following table to wire the DS...
this tutorial is wrong. Tested on STM32L010F4P6. To use the function HAL_RTCEx_BKUPWrite(&hrtc, RTC_BKP_DR1, 0xBEBE); no need to call HAL_PWR_EnableBkUpAccess(); or HAL_PWR_DisableBkUpAccess();. Actually, if the HAL_PWR_DisableBkUpAccess(); function is used, it is not possi...
Due to its popularity among hobbyists, academics, and professionals, Arduino boards are made to be simple to use and programmable. The Arduino board comes in a variety of models, each with unique features and capabilities. In this article I’m going to look in detail at the most popular Ar...
In this Arduino Tutorial we will learn how to use the DS3231 Real Time Clock Module. The DS3231 is a low-cost, highly accurate Real Time Clock which can maintain hours, minutes and seconds, as well as, day, month and year information. Also, it has automa
Introduction The STM32’s integrated RTC (Real-Time Clock) peripheral can be used to periodically wake it up from one of the various Low Power modes.
of a USB to TTL 3V3 Serial Cable, it is also possible to program the ESP-01 using an Arduino UNO, usingthis circuit, but don't use the UNO 3V3 power pin as the ESP-01's power supply it is only rated at 150mA and can cause problems when trying to debug a project that uses ...
