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.
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.
In this article we look at creating and displaying custom characters on an I2C 16x2 LCD to an Arduino, we chose an Arduino Uno but there is no reason this.
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.
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.
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.

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 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.
