DS1307 RTC IC: The DS1307 RTC IC is an 8-pin chip that keeps track of time and date using the I2C protocol. It uses very little power, less than 500nA. It can display time in seconds, minutes, and hours, and date in days, months, and years. It can also switch between 24-hour...
The ESP32-CAM is a full-featured microcontroller that also has an integrated video camera and microSD card socket. It’s inexpensive and easy to use, and is perfect for IoT devices requiring a camera with advanced functions like image tracking and recognition. The sample software distributed by...
timeClient.update(); // 更新时间信息 unsigned long epochTime = timeClient.getEpochTime(); // 获取当前时间的时间戳 #ifdef ESP32 struct tm *ptm = gmtime((time_t *)&epochTime); // 将时间戳转换为tm结构体 #else time_t ntpTime = (time_t)epochTime; struct tm *ptm = localtime(&ntpT...
Hi i check my device with other sketch and work well but when i load this sketch this error appears in the serial monitor “Failed to find MPU6050 chip”.i use i2c-scaner program and showed me it is well .i have this problem with basic_reading program also. i think this problem occurr...
For instance, if you need the time zone for Beijing (GMT+8), set utcOffsetInSeconds to 86060=28800.After programming the code, you can see the LCD the real-time and date. ESP32-S3-GEEK uses USB to UART to connect to the PC, open the serial port debugging assistant, and you can ...
ESP32 refers to the bare ESP32 chip. However, the “ESP32” term is also used to refer to ESP32 development boards. Using ESP32 bare chips is not easy or practical, especially when learning, testing, and prototyping. Most of the time, you’ll want to use an ESP32 development board....

If you are browsing through the specification sheet for an ESP32 device, you might run across the term “I2S”. At a glance, you may just think that it’s another form of I2C, and the “I2” does indeed stand for the same thing, “Inter-Integrated Circuit”. But that’s where the...
