In this article we are going to show you the 10 Most Useful Arduino Shields. This is our opinion based on the many shields that we have tried and tested.If you are new to the arduino platform then you will quickly realise that shields are a quick, easy and usually low cost way to easily add functionality to your arduino. Rather than building circuits on breadboards or designing prototyping boards you can simply attach a shield and get the functionality

In this article we look at 10 sensors and modules that you can use with an Arduino and various other micro controllers and development boards like the ESP32, ESP8266 and the Raspberry Pi that cost under $2

THE MQ-3 is suitable for detecting Alcohol, Benzine, CH4, Hexane, LPG, CO. The sensitivity of the sensor can be adjusted by using the potentiometer.

In this article we simply show you 4 examples using an RGB LED connected  to an Arduino
The RGB led we had was a common anode type, so if you only have common cathode one’s available you will have to modify the code examples later on

Here are a few code examples for the Wemos RGB LED Shield, the shield consists of 7 RGB LEDs (WS2812B-mini) each wtih 24-bit RGB color 9 optional control pins (Default:…

In this article we compare the BMP180 and SHT30 temperature sensors using a Wemos Mini and various shields. We will look and see if there are any significant difference in temperature readings.
