arduinoledclock's Issues

Add smoothing to analogue brightness read.

In lower light conditions the mapping of analogue photo resistor to FastLED brightness leads LED flicker fluctuations. A simple box filter should hopefully stop this.

Can use built in arduino smooth() example

Bluetooth serial input won't work with \r carriage return

currently only detects strings with a new line '\n'. If '\r\n' is sent together, Bluetooth commands are not detected correctly. BLE apps by default send '\r\n' forcing users to alter settings. To fix Need to insert logic to detect if string contains '\r' after parsing input and remove.
Alternatively could do read string until '/r' or '/n'

Create instruction readme

• Explain the concept and functionality of the WordClock
• Provide a parts list and possible distributors
• Create an easy to follow readme with example images of the fabrication process.

Add eprom memory functionality

Use the eprom memory of the ardunio board to save user settings
settings to save include:

• LED hue
• Birthdays set via bluetooth
• Brightness thresholds set via bluetooth

Add update of birthdays via bluetooth

Use the bluetooth serial connection to allow users to add new or delete birthdays to show on the clock

SVG Units

what are the units in the SVG files, inkscape is reading them as 172mm across rather than 230mm across. The center to center distance on the LED template is also 12mm and not 16.5mm, so the LED strip size called out won't fit the cutouts. The dividers have the slots at 1.5mm which matches the called out material sizes, however the length of them too is for a much smaller layout than the 9"x9" one called out.

The RTC doesnt seem to keep time after powering down

When powering down the clock doesnt seem to keep the correct time as previously. Might be due to the release of new DS3232RTC libraries

Add bluetooth threshold settings

The photoresistor on the clock uses a threshold to determine the brightness. This threshold will depend on the environment position that the clock is located.

For example:
The photoresistor in a clock positioned near a window will read vastly different to that in a clock in a darker corner of a room.

Two possible solutions:
1. Use Bluetooth serial connection to be able to adjust this threshold remotely and save the value in the eprom memory
2. more elegant; the clock learns the max and min photoresitor levels over a 24hour period from being powered on and autoupdate the threshold to eprom.

will likely implement solution1
