This project demonstrates how to use an ESP8266 microcontroller with a capacitive touch sensor module to detect the presence of metal objects. The sensor module outputs a digital signal that changes ...

Calibrate the sensors to ensure accurate readings. This involves setting baseline values for both the accelerometer (zero-point calibration) and soil moisture sensor (dry and wet calibration).

A new Instructables page has been created to make an eco-friendly DIY metal detector using an Arduino Mega just been combined with a 3.2 inch TFT LCD ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
