Arduino projects, make arduino rpm counter with arduino. Instruction;1) Connect all jumper wire as shown in diagram. 2) Connect IR LED to digital pin 13. 3) Connect IR Phototransistor (dark) to digital pin 2. Make sure shorter lead connected to digital pin 2 and longer lead to Ground. Upload this code to your arduino/** Optical Tachometer** Uses an IR LED and IR phototransistor to implement an optical tachometer.* The IR LED is connected to pin 13 and ran continually.* Pin 2 (interrupt 0) is connected across the IR detector.** Code based on: www.instructables.com/id/Arduino-Based-Optical-Tachometer/* Coded by: arduinoprojects101.com*/

Arduino HC-SR04 The Arduino HC-SR04 is different from most of those commonly seen on the market, which have 4 pins compared to 3 pins. But the operation principle is the same, transmit signal, and depends on when the signal is received to estimate the distance. Arduino HC-SR04 not only inexpensive but also practical, use a

[INTRO] This past semester, I decided to build a GPS receiver with an iPhone app that tracks it for my semester project. Here is a step-by-step tutorial to show you how you can build your own. [OVERVIEW] Architecture of my Real-Time GPS Tracker project. I’ll be using the diagram above to explain how the project

This was easily the most time I’ve spent producing an Arduino Tutorial. I’ve been sporadically walking around NYC with this Arduino GPS for weeks as I’ve tweaked the code and gotten it just right. If it wasn’t obvious from the title, this tutorial will teach you how to use an arduino paired with a GPS Module

These two chips provide an easy way to control either an array of 64 Led’s or up to eight digits made of 7-segment displays with a minimum of electronic components. Besides the chip itself you will need only a single resistor and one or two capacitors. Data is send to the chip using a SPI-compatible

Oscar Gonzalez gives us a simple tutorial for speed controlling a PC FAN and reading a LM35 temperature sensor with an Arduino microcontroller. He covers the use of an optocoupler, PWM (Pulse Width Modulation) and reading analog voltages with the Arduino. He even has a video showing the fan speed control in action. This article
