The first step: Install The Arduino IDE:The Arduino IDE is an app that you can download and install fairly quickly. The IDE provides a code editor as well as a tool to upload your code to your Arduino. There are instructions specific to each operating systemon Arduino’s website. ...
The I2C pins on the Arduino Nano are A4 (SDA) and A5 (SCL), these pins can be used to communicate with I2C devices such as sensors, LCD displays, and other microcontrollers. To use these pins, you will need to use the Wire library, which is built into the Arduino IDE: It is impor...
I'm running Windows 11 and connectng to the board via USB. I get the same errors whether I'm connected through a USB hub, or connected directly to a USB port on the computer motherboard. When I'm using configurePin and readVoltage for analog pin...
Choose the board, COM port, hold down the BOOT button, click upload and keep your finger on the BOOT button pressed. When the Arduino IDE starts sending the code, you can release the button and wait for the flashing process to be completed. Now, the ESP32 is flashed with the new firmw...

No Issue found with Arduino Core 3.1.0. Board Configuration: Sketch executed: // NB. "USB CDC on Boot=Disabled" // ESP32-C3 void setup() { delay(5000); pinMode(18,INPUT); // does NOT remove USB-JTAG pulses from GPIO-18 pinMode(19,INPUT); // DOES remove USB-JTAG pulses from ...
In this tutorial, you’ll learn about ESP32 I2C communication protocol (in Arduino IDE). We’ll discuss how ESP32 I2C works, how to change I2C default pins (SDA, SCL), how to connect multiple I2C devices on the bus with proper addressing, and how to create an ESP32 I2C scanner to ...
I build a circuit on a breadboard using a ESP-WROOM-32 (equivalent to a nodemcu 32S) and connected pins 34,35,36,39 to a momentary button with a 3.3k pullup resistor. A diagnose program is report that all the buttons has been pushed down at the same moment while a only click on ...
On the positive side, together with needles, nails, screws, broken glass, and other sharp objects, pins may be placed in a bottle filled with urine as a protection from evil (seewitch bottle). An old British tradition says that if a girl has been betrayed, she can get revenge by throwi...
