New product: 16×32 RGB LED panel + Arduino Uno connector shield

Posted on April 18, 2016 by R-B Leave a comment

Today, we have added a new and colorful product to our Tindie store. It is a colorful RGB LED matrix panel kit that includes a 16×32 RGB panel, a RGB connector shield for Arduino Uno, a 2×8 IDC cable, and a power supply connecting cable for the RGB panel. The RGB panel operates at 5V and requires 12 digital I/O pins of Arduino Uno for full control of the display. We designed the RGB matrix connector shield to allow super easy connection setup between the LED display panel and the Arduino Uno board.

16×32 RGB LED matrix panel kit

Features:

Operates at 5V (2A rated power supply is recommended)
Dimensions are 192mm x 96mm (7.6”X3.8”)
LED spacing or pitch : 6mm
Compatible with Adafruit’s RGBMatrixPanel Library
RGB connector shield and IDC cables are included (no additional wires are needed for connecting the matrix to Arduino Uno)

What will you get in the package?

One 16×32 RGB LED matrix panel
One RGB connector shield for Arduino Uno
One IDC cable to connect the RGB matrix panel to the RGB shield
One power supply connector for the RGB matrix

Note: The power supply is not included. It requires a 5V, 2A power supply with a 2.1mm x 5.5mm DC connector. The LED matrix also works fine with a 1A power supply (like from a cell phone charger) applied through the USB connector of Arduino Uno.

RGB Matrix Connector Shield

Update (Sep 22, 2016)

The RGB Matrix driver shield has been revised recently and the new version has the DS1307 RTC chip on board. The I2C signal lines are also hard wired to Arduino A4 and A5 pins.

16-channel wifi remote using ESP8266

Posted on April 12, 2016 by R-B One comment

Hari Wiguna has shared on Hackaday.io this interesting scheme of making a 16-channel Wifi remote using ESP8266 and PCF8574 I/O expander chips. PCF8574 device provides an 8-bit I/O expansion for any microcontroller through an I2C interface. This Wifi remote consists of a transmitting remote unit and a receiving control unit, both of which use one ESP-01 module and two PCF8574 devices. The remote unit has 16 push switches connected to the PCF8574 I/O pins, whereas the receiving unit has 16 LEDs connected in a similar fashion to the two PCF8574 chips. The remote ESP-01 module operates as a web client that reads the states of the push switches and send that info to the control ESP-01 module, which operates as a web server, as part of the web request. When a button is pressed on the client side, the web server responds to this request by changing the logic state of the corresponding LED on its end.

Arduino wireless joystick

taifur has posted great instructions about how he built an Arduino powered wireless joystick that can be used as a console for playing PC games. His design features a joystick module and 5 buttons, with which you can control the mouse cursor as well as implement any 5 keyboard functions (such as W, A, S, D and Space are the most commonly used keyboard buttons for games).

Arduino wireless joystick

My Arduino wireless joystick has two parts. One is receiver which will be connected to PC via USB port. Another is transmitter and this is the actual joystick in your hand. As I mentioned earlier, Receiver unit should contains 32U4 comes equipped with a full-speed USB transceiver. For the purpose I used cool & tiny Pro Micro from Sparkfun. You may used others variant like Arduino Micro or DUE.

ATtiny keychain game console

This tiny keychain game console is pretty neat and is based on ATtiny85 and and a SSD1306-driven OLED screen. The author has also shared the code for the UFO Escape game for this console.

ATTiny85 game console

I finally had some free time to make something fun and decided to write a new game for the Attiny85 ssd1306 keychain. I reused the sleep, display and interrupts code from the “Breakout” game I created a while ago.

This time I wanted a more addictive game. The game had to be playable using just the two buttons. I thought a racing game might be a good choice but the landscape screen is more suitable for a side-scroller. So I settled for an obstacle avoiding side scroller. Similar games include the recent Flappy Bird, Nyan Cat and many variations of the Helicopter game.

New product: ASK RF transmitter and receiver kit

Posted on April 6, 2016 by R-B Leave a comment

Today, we have added a new product to our Tindie store. It is a complete set of ASK RF transmitter and receiver modules for enabling wireless data transfer between two Arduinos. The kit consists of high quality ASK transmitter and receiver modules (433MHz carrier) along with matching copper spring antennas.

There are tons of other cheap ASK modules available in the market. Most of them do not come with antennas and the user has to cut out and install a right size wire antenna for reliable operation. Our kit includes a complete solution with copper spring antennas. Following features makes our kit special.

High quality circuit board and components
Include matching spring antennas made of copper
Very compact size
Works with both 3.3V and 5.0V platforms.
0.1″ pitch through holes header connector (right-angled headers included) that makes it breadboard friendly
Half-cut through holes for easy PCB mount
