Using the TCS230/TCS3200 Color Sensor with an Arduino

TCS3200 Color Sensor Module

In this article I will endeavour to show how to detect colours with an Arduino connected to the TCS230/TCS3200 colour sensor.

The TCS3200 colour sensor can detect a wide variety of colours based on their wavelength. This sensor is specially useful for colour recognition projects such as colour matching, colour sorting, test strip reading and much more.

Using WS2812B Addressable RGB LED Strips with Arduinos

WS2812B LED Strip
This article is about my experiments with the WS2812B LED strip, which is an addressable RGB LED strip. This information should also work with other similar LED strips, such as strips of the WS28XX family, Neopixel strip, among others. The WS2812B addressable LED strip comes in several varieties that differ in size, sealant or LED density. Choose the one that best fits your purpose.

Using a 0.96 inch OLED Display with Arduino Microcontroller

0.96" OLED Display
In this article I will show how to use the small 0.96 inch OLED display with an Arduino Microcontoller board to build a very basic Weather Station.

Introduction to using the BMP180 barometric sensor with Arduino

bmp180 barometricsensor
The BMP180 barometric sensor (model GY-68) in the following two images is a very small module with 10mm x 10.1mm (0.039in x 0.043in) footprint. This guide is also applicable for other similar barometric sensors.

Using the HC-SR04 Ultrasonic Sensor with Arduino

The working principle of an ultrasonic sensor is simple and use high-frequency sound waves that are evaluated when the sensor received back the waves. To determine the distance between the robot and object, the sensor measure the elapsed time between sending and receiving the waves.

Using a Membrane Keypad with an Arduino

Membrane Keypad
With this tutorial, you will be learn to access any keypad, and have it interact with a microcontroller. You can salvage these keypads from old telephones or you can purchase them from most electronics store for less than $2. They come in wide variety of shapes and sizes. The most commons sizes are 3×4 and 4×4, and you can get keypads with with words, letters and numbers written on the keys.

ESP8266 Web Server using Arduino IDE

In this project you’ll create a standalone web server with an ESP8266 Wi-Fi Module that can toggle two LEDs.

Secure Access using MFRC522 RFID Reader with Arduino

This Article shows a simple example on how to use the MFRC522 RFID reader, with a quick overview of the specifications, and a demonstration project using an Arduino.
