In this article we look at an Ambient Light sensor, the LTR-329 and connect it to an Arduino Uno Sensor Information The LTR-329 provides 16-bit light measurements for both Infrared and Visible+IR spectrums. Subtract one from the other to get …

In this article we look at an Ambient Light sensor, the LTR-303 and connect it to an Arduino Uno Sensor Information The LTR-303ALS is a low cost,small, I2C Ambient Light sensor. The LTR-303ALS comes in a 2.0×2.0×0.7mm 6pin DFN package. …

In this article we look at creating and displaying custom characters on an I2C 16×2 LCD to an Arduino, we chose an Arduino Uno but there is no reason this will not work with a different Arduino board. This can …

On this page we look at Scratch for Arduino – s4a. We will be using a Keyestudio board which contains a variety of LEDs and analog inputs for testing. Scratch is a basic environment for learning development, you drag and …

In this example we will add bluetooth support to our Arduino, there are several low cost modules labelled either Hc-05 or HC-06. Here is a picture of one of them In this example we will connect one of these modules …

I recently tried out an example for a DS18B20 temperature sensor. The code example mentioned 2 libraries, so I went forward and downloaded them and imported them into my IDE but was disappointed to see an error like this when …

In this example we’ll be using the Microchip 24LC256 EEPROM, this chip when connected to an Arduino can increase the available memory space by 32kbytes. Here is a pinout of the IC The address pins, A0, A1, and A2, which …

The is a 16-bit, general purpose parallel I/O port expander for I2C bus applications. The 16-bit I/O port functionally consists of two 8-bit ports (PORTA and PORTB). The MCP23017 can be configured to operate in 8-bit or 16-bit modes. Lets …
