For example, do not power your ESP32 dev kit via the 5V pin using a 10V input while at the same time you have the module connected to your computer via USB. This will surely damage your module, and perhaps even your computer. With this, you should have a good understanding of what t...

Esp32 cannot connect. I have used my computer to test that WiFi has 2.4G band and can be connected through 2.4G band. What should I do to connect the eps32 to the router through the 2.4G band? Who has experienced similar problems? Can you help me? thank you very much!
The ESP32 is intended to be suitable for low power applications - in other words, running on batteries. The optimal voltage for the ESP32 is 3.3V. The nominal voltage of a Li-ion battery is 3.7V but it can be anywhere between 3V and 4.2V. Many of the development kits come with the...
It's an BLE lock and key(s) project. I want to pair a number of keys via BLE 5.x to one single Bluetooth lock. The keys could be any thinkable BLE Devices... ESP32-C3, Smartphones... that send a "open" or "close" information to the lock. ...

1] Install the ESP tool To erase the ESP32 Flash Memory, you first need to install the ESP tool on your computer. Open the Windows Terminal or Command Prompt and type the following command. After that, hit Enter. py -3.13 -m pip install esptool ...
In this manner, we can connect up to 8 LCDs to the same line. There is one more thing, the ESP32 takes 7 bit address for the I2C device. All the functions, which are included in the library of ESP32 will shift this address to the left by 1 bit, 0x27<<1, and the LSB here ...

You may like to check our previous project on high voltage measurement with other microcontrollers. Although a different microcontroller is used in these projects, you can apply the same concepts to ESP32 ADC for measurement of current, voltage, power factor and ac power. ...
