Plug in IR Detector. Make sure the dome on it is facing you. 2. Connect the leftmost pin of the detector to Arduino Digital pin 2, the middle pin to Ground, and the rightmost pin to +3.3V. 3.

We build a low-cost groundwater detection system in ... While we could use a store-bought multimeter to measure voltage, building our own voltmeter out of an Arduino ... Building an Arduino ...

Over on Adafruit, they show you how to build your own that hooks into IFTTT so you can be alerted any way you like when the door opens. The system here uses a cheap Arduino board, a few sensors ...

The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

There are other metal detector projects using AVR and PIC. This one is nice and simple. I do wonder why the 7.64khz frequency was chosen instead of something in the 15k to 20k range wasn’t used.

Sparki uses an ATMega32 processor and a custom bootloader to run Arduino functionality. It has a distance sensor to calculate the distance to walls and objects, an accelerometer, light-sensing ...
