DAC Shield For Arduino Nano using MCP4725

This project features an easy to use Digital to Analog converter (DAC) shield for Arduino Nano. The project is built using MC4725 12Bit DAC IC over I2C communication. The shield directly seats on Arduino Nano and also can be used as stand-alone DAC converter that can be connected to other micro-controller board with help of 5 pin header connector. Output is 0-5V. PCB jumper J1 provided to select the address in case of using multiple modules on the same I2C .

Shield also provided with high current driver circuit, which converters voltage to current and can be used to drive Laser diode or LED. Maximum possible load 500mA.

The Little Buddy Talker – Arduino Compatible Speech Chip Set

Small, versatile, fun, and inexpensive! Use the 254 word library to bring speech to your Arduino projects! Speak, Arduino, Speak!

About a year ago, I designed an Arduino shield that allowed for you to add voice to your electronic designs.  I’ve since been able to minimise that design into a much less inexpensive, and smaller unit.  This unit has a 254 word library that consists of colours, commands, months/days/time, numbers, directions, feelings, units of measurement, security words, math lingo, and general words; all of which are spoken by “Lucy” – A lovely female voice with an English accent! Meet “The Little Buddy Talker” Arduino compatible speech kit set!  It is Production Ready, and eager to land in your hands!

The project is live on kickstarter and has 29 days to go.

1Amp Constant Current LED Driver Shield for Arduino Nano

1A Constant current LED driver shield for Arduino Nano has been designed for verity of LED related applications. The shield provides accurate LED current sink to regulate LED current in a string of LEDs or single LED. The LED current is mirrored from the current flowing from the RSET Preset PR1. On board 1W LED is used for testing purpose. External high Wattage LED or multiple LED string can be connected by pulling two wires from the PCB and this shield fit directly on back side of Arduino Nano. Shield also has on board tactile switch connected to Digital D2 pin using pull down resistor if required for any application. On board preset helps to set the maximum constant current. PWM input pin connected to Digital pin D6 of Nano to control the LED intensity. Example code FADE-IN/FADEOUT helps to test the shield.

Paperino, The ePaper Display Shield

ePaper displays  (EPDs) are becoming a trend in application, just like the display used in Amazon Kindle,  for their low power consumption due to the  to the underlying ‘bistable’ display technology. These displays can continue to show information without any power at all. It is only required while updating the display with new information, otherwise there won’t be any power consumption.

Providing such revolutionary displays to your applications will be a professional approach. For this, a new crowdfunding campaign is providing Paperino, an easy-to-use, micro ePaper shield for the Particle & Arduino community. Paperino simplifies driving ePaper displays with clean, simple, and short script examples.

Thanks to the plug-and-play shield for particle family, Paperino can be used with the following boards: Photon, Electron, or Bluz without manual wiring. It can also be wired easily to be connected with Arduino and other compatible boards.

Paperino Features

Glass-free Display

Paperino is lightweight and thinner than other ePaper products because it uses a glass-free ePaper display from Plastic Logic. It weighs 1.2 grams and is only 0.5 mm thick.

Supports Four Gray Levels

Unlike many other ePaper products out there, Paperino can support four gray levels instead of two (black and white).

Fast, Partial Updates

You don’t have to wait for slow, full screen updates to load. With Paperino, you can quickly update only parts of the screen.

Accelerometer

The integrated accelerometer lets you interact with your Paperino in all sorts of ways, including tap sensing. Tap sensing capability can trigger screen updates or wake up your microcontroller.

Paperino Specifications

The Paperino breakout board can be used for manually wiring your favourite, Arduino-compatible microcontroller with 3.3 V and >4kb of free RAM.

  • Resolution: 148 x 70 px
  • Pixel density: 150 ppi
  • Grey levels: 4
  • Weight: 1.2 g
  • Thickness: 500 µm
  • Power consumption: 4.5 mA (mean current for typical image update)
  • Operating conditions: 0°C .. 40°C
  • Storage conditions: -25°C .. 50°C

You can pre-order your own Paperino for $20 and with a driver board for $30. The crowdfunding campaign still has 16 days to go, and you can learn more details by checking it out.

VGADuino-II : The New 256 Color Graphic Shield for Arduino

Arduino is pretty much famous for the numerous shields it has. These plug-and-play shields make our life a lot easier while working on some complicated projects. Among all other shields, graphic shields are getting more and more popular. A graphic shield lets you show text, numbers, shapes, and even small images on a screen, using Arduino. VGADuino-II is a new graphic shield which lets you use your TV or any monitor with VGA 15 pin as a large screen for Arduino.

It’s very exciting that you won’t have to rely on those small displays which are stacked on the shield itself, anymore. Rather you are getting a whole TV or VGA monitor to display your data. As  Masih Vahida, the creator of VGADuino, says:

VGADuino is a shield that is made for Arduino with all the libraries and samples that user can easily stack it on the Arduino board and starts programming. it can connect Arduino to any kind of TV or Monitor with VGA 15 Pin connector.

Key Features:

  • Internal functions to draw various shapes with AT-Commands and Arduino libraries
  • 11 Different font sizes with standard ASCII characters support
  • 256 color, 8bit RGB format
  • Having access to each pixel individually
  • Standard VGA DB15 output
  • Screen resolution: 800×600 60Hz
  • Actual pixels: 400×300 60Hz

Technical Details:

In VGADuino-II, NXP-LPC1756 ARM chip is used as the main microcontroller and XILINX XC95144XL CPLD for refreshing the display and taking care of the sync signals. There is also an SD Ram to keep the screen’s pixel color data.

In this version of VGADuino, each pixel is one byte, that means each pixel has 256 colors which are in standard 8bit RGB format. (3 bits for Red, 3 bits for Green and 2 bits for Blue).

It communicates with Arduino over UART using predefined AT command set. All relevant Arduino libraries are available to implement in code. The user can choose among all 11 fonts with definable background and foreground color of text.
