Learning

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 write to the EEPROM which is on the micro controller of the Arduino The supported micro-controllers on the various Arduino and Genuino boards have different amounts of EEPROM: 1024 bytes on the ATmega328P, 512 bytes on …

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 previous posts we showed some examples for the 4067 16-Channel multiplexer – Arduino and 4067 LED example The HCF4051 device is a monolithic integrated circuit fabricated in MOS (metal oxide semiconductor) technology available in SO-16 and PDIP-16 packages. The HCF4051 analog …

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 …

In this example we connect an Arduino to a L9110 fan module. This is a commonly found, basic low cost module which consists of an L9110 chip and a small motor attached. You need 4 connections between the arduino and …

I fancied trying the https://www.arduino.cc/en/Tutorial/CapacitanceMeter , to look at the theory visit that page. I was wanting to see how accurate this is and also wanted to test this on other variants such as the Chipkit and the MSP_EXP430G2 to …

A keypad is a nice simple method of accepting user input into your project. These come in a number of styles and generally there are 2 types a 3×4 keypad and a 4×4 keypad. The numbers stand for the rows …
