I had 3 types of key pads that I played with switches on a PC board, membrane switch, soft-touch See the pictures below. I started with the Keypad library for easy matrix style keypad mapping. I had to play around with the Row and Column mapping to get my Key Pad switch matrix to work.
The pin-out in the documentation wasn't correct on any of the keypads.
So once I determined the correct pin-out, the code worked perfectly. Here is code snippet showing how to use the Keypad library: I really didn't have any problems getting the display to work. The 2x16 character display included in my Arduino kit didn't work so I ordered a 4x20 character display and it worked the first time I tried it.
After writing the initial version, I spent about 4 or 5 hours debugging the code.
I soon realized I should have created a state diagram and used state driven logic. So I deleted most of the code and wrote a test plan and state diagram to match the input protocol.
|Shop by category||Some wires First steps I came up with this idea while I surfed the Arduino website. Some people showed, not how to make the bridge between the software and the lights, but how to generate the DMX signal to comunicate directly with the machines, which was not exactly what I intended.|

Here is the test plan with all the input protocols defined in spreadsheet format: State Diagram in Diagram Format Once I have the state diagram completed, I coded the input part of the projects in about 1. Introduction to State Machine Logic If you aren't familiar with or haven't used state machine logic in programming, it is the easiest way to to break complex problems into manageable states and state transitions.
One of the easiest ways to implement a state machine is to use a switch statement. In my opinion it is the only way to implement serial input commands. Example of a state machine using a switch statement:This shield has been designed with flexibility in mind and allows the user to choose between several Arduino pins for digital input and output of DMX data, it supports a microSD slot and also has the serial connection to support a serial LCD display.

Both Arduino’s use this library for the DMX control. Of course I used my own library to run the MP3 Shield, and pulled in this easy library to run the MP3 Trigger board.
Witch’s Lair was a scary scene showing a witch churn her cauldron in the kitchen. This I2C 16x2 Arduino LCD by DFRobot offers RGB colour-changing capabilities, and is perfect as a sleek and elegant microcontroller display.
For the Arduino, you write a value from 0 to on a PWM pin, and the Arduino library will cause the pin to output a PWM signal whose on time is in proportion to the value written.
Menu RGB Led Strip controlled by an Arduino 12 January on arduino, led, mosfet, temperature, light I bought a few weeks ago some quite cheap 5 meters RGB LED strips (60 LEDs per meter) on timberdesignmag.com intent is to drive them with a custom Arduino receiving commands over some XBees.
