The beginner’s guide for hobbyists and makers unlocks some of the practical secrets behind lightning detection design.

An 8-sensor LDR line following robot using ESP32 with dual-threshold hysteresis algorithm. The project includes both Arduino IDE and ESP-IDF development environments, plus threshold calibration tools.

Unlock New Possibilities with Arduino Pro Connectivity Solutions The combination of the Arduino Portenta Mid Carrier and the Arduino Pro 4G Module opens up a world of possibilities for your projects.

MEMENTO ESP32 Camera Module, features an ESP32-S3 chip, supports Circuit Python and Arduino. It includes an OV5640 sensor 1.54" TFT display.

The amount of light reaching the LDR from the LED decreases as the pipe is bent, and with a simple divider circuit a voltage can be read by an Arduino.

The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

Step 3: Making the Circuit Now, as we know how the components work, let’s go ahead and assemble theses components together and make a circuit as shown below. The Ultrasonic sensor is powered by 5V ...
