The LX1972 is a low cost silicon light sensor with spectral response that closely emulates the human eye. Patented circuitry produces peak spectral response at 520nm, with IR response less than ±5%, of the peak response, above 900nm. The photo …

The Arduino nano is a very nice board, it has the same microcontroller as an Uno, all of its I/O come out to headers, it uses mini usb and its small size make it ideal for projects where space is …

There are a few development systems available which are Arduino based which are designed to make it easier for beginners and young people to get started. One of these is the Grove system and the other is this one which …

Arduino and MCP3424 A/D converter example, lets look at the device. The MCP3424 is a four channel low-noise, high accuracy delta-sigma A/D converter with differential inputs and up to 18 bits of resolution. The on-board precision 2.048V reference voltage enables …

In a previous example we took a look at the HDC1008 – http://www.arduinolearning.com/code/hdc1008-sensor-example.php This example used a library from Adafruit but we wanted to show you how to do the same thing with no libraries., here is a reminder of how …

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 …

SHT31 is the next generation of Sensirion’s temperature and humidity sensors. It builds on a new CMOSens® sensor chip that is at the heart of Sensirion’s new humidity and temperatureplatform. The SHT3x-DIS has increased intelligence, reliability and improved accuracy specifications compared …

The PCF8591 is a monolithically integrated, and a separate power supply, low-power, 8-bit CMOS data acquisition devices. The PCF8591 has the four analog inputs, one analog output and a serial I2C bus interface. PCF8591 three address pins A0, A1 and …
