If your Arduino soil moisture sensor isn't working, check these common issues: verify all wire connections are secure, ensure you're using the correct Arduino pins (A0 for analog, digital pin for ...

Ultrasonic sensor Arduino code with LED. Arduino Ultrasonic Sensor-LED. We are going to learn how to: If the object is close to ultrasonic sensor, turn LED on; If the object is far from ultrasonic ...

The Arduino IR sensor module code is very simple and easy to understand. We are just basically keeping track of whether the input to pin D9 is HIGH or LOW. We initialize our code by declaring two ...

This Arduino code is designed to read data from five gas sensors connected to an Arduino board. The sensors include MQ8, MQ4, MQ9, MQ7, and MQ135. The code reads analog data from these sensors and ...

Arduino Uno is a microcontroller board that is used to perform various tasks in different circuits. It needs a Code in C language to operate. We are using the Arduino Uno board in this project but you ...

This project combines an Arduino Nano, a TCS34725 color sensor and a buzzer to assist color blind users. Electronic systems can help the visually impaired. ... Therefore, we do not use ready-made ...
