ESP32 provides three universal asynchronous receivers and transmitter (UART) ports such as UART0, UART1, and UART2 that work at 3.3V TTL level. These three serial interfaces are hardware supported. Each of them exposes 4 pins: RX, TX, RTS and CTS. However, the Arduino IDE only uses RX ...
UART1 GPIO9 GPIO10 Yes but require pins reassignment UART2 GPIO16 GPIO17 Yes Check this tutorial for more details: ESP32 UART Communication Explained with Example Touch sensor pins of Devkit ESP-WROOM-32 provide onboard 10 capacitive touch sensors. So you don’t need to use separate touch ...
The pins are explained in the L298N motor driver inputs section. Then we also setup frequency of the PWM signal, the resolution of the PWM signal and the starting predefine the variable for duty cycle of the PWM signal. Frequency defines the total time the pwm signal takes to complete a ...

After a few utilizations, I can't read or write data from the potentiometers anymore. I didn't put any zener diode on digital pins to avoid overvoltage peak but I also noticed that sometimes, I didn't respected the order of powering for the component, as explained in the datasheet. ...
So this pins can be read with a pill-up resistor to know the device state. Reply Diego 22 September, 2022 at 15:06 Very good project. One question, in the case of wanting to program the ESP32, would it be necessary to disconnect the battery power, or would it be possible just by ...

In this ESP32 ESP-IDF SPIFFS web server project, we will create and store HTML and CSS files in SPI flash file system, and through which we will build a web server that will control the output GPIO pins of the ESP32 module by toggling the onboard LED. ...
I've also soldered the pins and noticed that the backlight works purely because of the current going in. I don't know what's wrong or if my board is faulty or something. And as the cherry on top, the board stopped being recognized by my computer (I have test it on another computer...
What is the ESP32 sensor on the mpu6050? What are pins 21 and 22 on the ESP32? Sending and Storing Data via BLE at Regular Intervals using ESP32 Question: My aim is to create a sensor that detects vibration using an accelerometer connected to the ESP32-DevKit board. The sensor's objec...
