Gold Detector with Arduino - G3ar

Whistle Detector. This example reads audio data from an Invensense's ICS43432 I2S microphone breakout board, and uses the input to detect whistling sounds at a particular frequency. When a whistle is detected, it's level is used to control the brightness of the built-in LED Arduino Sound library – Your reference for the Arduino Sound

Arduino Metal Detector Project with Code and Circuit Diagram

/22/2013The metal detector has excellent sensitivity and by changing the SENSITIVITY value in the Arduino sketch you are able to tune it for both small and large objects. Here is the source code if you want to build one yourself. Happy hunting!

Arduino Playground - MQGasSensors

Metal Detector is a security device which is used for detecting metals which can be harmful, at various places like Airports, shopping malls, cinemas etc. Previously we have made a very simple Metal detector without a microcontroller, now we are building the Metal Detector using Arduino. In this project, we are going to use a coil and capacitor which will be responsible for the detection of metals.

Arduino Lie Detector - Hacksterio

Gold Detector with Arduino. April 13, 2015 Kraken Electronics. I already posted an article about a DIY gold detector, but this time you can test a much simpler DIY gold detector with an Arduino. Stuff needed. An Arduino. I tried with (i had it from PS3).

PIR (motion) sensor ID: 189 - $995 : Adafruit Industries

Arduino board I’m using is Arduino UNO. I have also designed an LPG Gas Leak Detect using Arduino using this MQ2 Sensor. So, let’s get started with How to design Smoke Detector with Arduino MQ2 Sensor. First of all, we need to connect some jumper wires between Arduino and MQ2 smoke sensor shield.

Arduino Motion Sensor/Detector using PIR Sensor: Complete

Below is the PIR motion sensor Arduino circuit diagram and underneath it, I go into step by step on how to put this device together. 1. First, run a wire from the 5V pin to the positive rail on the breadboard. 2. Now run a wire from the ground pin to the ground rail on the breadboard. 3.
