Introduction

This part of the wiki concerns the Product Specification of the “Nijntje to. Alice” product. It describes the main components, behaviour and their interactions.

The “Nijntje to. Alice” product consists of an interactive painting. The basic configuration shows a typical Nijntje scene from Dick Bruna. Flashing LED's add extra atmosphere to the scene. the LEDs can be put in the following groups: stars, fireflies, lantern and the eyes of and Owl.
Separate modules exist, which depict scenes from “Alice in Wonderland”. These modules can be attached and detached from the interactive painting. Attaching a module to a specific place of the scene will modify the behaviour of the LED's.

Mechanical Aspects

The painting shall have the following dimensions: 60 cm width en 45 height. The Painting has the service identifier: ANIN and nomenclature: ASSY, NIJN

The PBA shall have the following dimensions: 10 x 15 zijn The PBA has the service identifier: PNIN and nomenclature: PBA, NIJN It shall contain the connectors for the battery, hall sensor input and LED outputs The PBA shall have 4 mounting holes for M3 bolts. The mounting holes shall have an asymmetrical orientation wrt. each to prevent confusion of the mounting orientation. A mounting hole for an M3 bolt shall have a diameter 3.2 mm. The mounting hole shall remain non-plated.

The main control shall consist of a standard Arduino Duemilanove. Upward compatibilty to Arduino One will not be part of the design. The main control has the service identifier: CNIN and nomenclature: PBA, CONTROL

Firmware and source code for the main control shall have the following nomenclatures:
firmware: FW, NIJN
source code: SRC, NIJN

Electrical Aspects

Power

Batterij

Capacity of one 9 V battery: 450 mAh

Duration before running out: 3 hours. (using 133 mA at full load)

Adapter

Adapter moet makkelijk 200 mA aankunnen.

Inputs

Hall sensor input

On/Off switch

ANIN-S2 connects to PNIN-X2 and shall cut the power from the battery to the complete Assy.

Reset Switch

PNIN-S1: This switch has the same function as the reset switch CNIN-S1 CHeck the schematic of the Waveshield how this is done.

DIAGLED This LED is used for diagnosis purposes and consists of a single green LED. It will be individually controlled by FW, NIJN using a discrete on/off output directly tied to a digital I/O of CNIN. A current source will drive the LED between 0 and 2 mA.

FLYLED[0-7] These LEDs light up the fireflies and mushrooms, it consists of 8 full colour LEDs with and outputs for Red, Green and Blue. This results in 24 outputs for all the FLYLEDs. They will be individually controllable by FW, NIJN using discrete on/off switching. A current source will drive the LEDs with 3 mA. when they're active.

LIGHTLED This LED functions as the flame in Nijntjes lantern and consists of a single Yellow LED. It will be individually controlled by FW, NIJN using a PWM output with up to 32 distinct levels. A current source will drive the LED between 0 and 4 mA.

OWLLED[0-1] These LEDs illuminate the eyes of the Owl in the painting and consist of 2 Yellow LEDs. They will be individually controllable by FW, NIJN using discrete on/off switching. A current source will drive the LEDs with 4 mA. when they're active.

STARLED[00-10] These LEDs light up the night sky and consist of 20 white LEDs. They will be individually controllable by FW, NIJN using discrete on/off switching. A current source will drive the LEDs with 2 mA. when they're active.

The powerLED of CNIN will remain visible in the final assembly. So an extra power LED will not be necessary.

Behaviour

State Nijntje
The main-control shall enter the state Nijntje if MUSHPRSEN has a high level.
STARLED[00-19]: LED produce light continuously
FLYLED[0-7]: The firefly change continuously from colour between Red and Yellow
LIGHTLED: Light flickers continously at analogue levels.
OWLLED[0-1]: Lights are most of the time on. The Owl will blink with the left, right or both eyes ones in a while.

State Alice
The main-control shall enter the state Alice if MUSHPRSEN has a low level.
STARLED[00-19]: LED twinkle at random with most of them (80 %) active most of the time.
FLYLED[0-7]: The LEDs will shine white continuously.
LIGHTLED: The Light is off.
OWLLED[0-1]: Lights are most of the time on. The Owl will blink with the left, right or both eyes ones in a while.
