In our previous look at the Easy Module Shield v1 – Arduino Easy Module Shield v1. We took a look at the shield and had a simple example looking at the LDR and the pot. In this example we will show examples …

I spotted a couple of new shields when I was browsing some online shopping sites, so I though I would take a look at these. Initial impressions suggest these would be ideal for beginners. Shield 1 This shield integrate various …

Freescale’s MAG3110 is a small, low-power, digital 3-axis magnetometer. The device can be used in conjunction with a 3-axis accelerometer to realize an orientation independent electronic compass that can provide accurate heading information. It features a standard I2C serial interface output …

The APDS-9930 provides digital ambient light sensing, IR LED and a complete proximity detection system in a single 8 pin package. The proximity function offers plug and play detection to 100 mm thus eliminating the need for factory calibration of …

In this example we will take the SHt31, read the temperature and humidity and send this data to an online IoT platform, in this case we will use Thingspeak. To achieve this we will need an Arduino Uno with an …
