WS2812 family is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. effectively ensuring …

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 …

In a previous example we used the 4067 to flash some LEDs – Arduino and 4067 LED example but you can also use the CD74HC4067 multiplexer / demultiplexer to read analog values from all 16 channels. This gives you the ability …

One of the fun things about Arduino’s is coming up with projects to use Arduino’s and various sensors or modules. In this project I was thinking about an example that would detect the presence of a person. In the world …

The 4067 was one of the IC’s that I wanted to connect up to various microcontrollers as it looke dextremely useful, here is a quick description from one of the datasheets with an overview of the functionality The HEF4067B is a …

In this example we will connect an XBox 360 (USB) joypad to a USB Host shield and flash some LEDs depending on what button was pressed on the joypad You will need a USB host shield, connect this to an Arduino UNO …

The ProtoSnap is an Arduino-compatible development platform aimed at teaching the basics of Arduino programming as efficiently as possible. It does not require any assembly, wiring, or soldering, so you can jump right into programming the ProtoSnap to control LEDs, buzzers, light …

A mercury tilt switch is a switch which opens and closes an electrical circuit when it is tilted at certain angles. When it is tilted a small amount of the liquid metal mercury makes contact with metal electrodes to close …

This shield uses a 4 digit, 7-segment display to give you the data you need. You can use it to make clocks, timers, show sensor data, or anything else you can dream up. Here is a picture of the shield …

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 Ardumoto  is a motor shield for Arduino that will control two DC motors. Based on the L298 Dual Full Bridge Driver The Ardumoto can drive up to 2 amps per channel. The board takes its power from the same Vin …

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 …
