I started documenting the pxlBlcks (which I had put off for a long time) in November 2020 after Hackaday.com announced the \"GoodBye 2020\" challenge. (More info about it here: https:\/\/hackaday.io\/contest\/175608-goodbye-2020\/details<\/a><\/em><\/strong>)<\/p>\n\n\n\n

I had used the pxlBlcks for a long time, but as so often I never found the time\/motivation to write it down.<\/p>\n\n\n\n

If you have read the description of the challenge mentioned above, you might have noticed that the challenge fits very well to the functionality of the pxlBlcks. Scrolling texts could be displayed on it for a long time. So, for example, a \"Good Bye 2020\" message can be displayed without major problems. <\/p>\n\n\n\n

Thanks to a tip from one of the first testers of the pxlBlck plugin, I came up with another idea how to visualize even better when the year 2020 is finally behind you: A kind of loading bar that visualizes how many days of the year 2020 are already gone and accordingly still remain.<\/p>\n\n\n\n

For this purpose I have implemented a new command in the pxlBlck plugin with which up to five relative (percent) values can be shown on the display. So you can display not only the end of a period but also various scaled (if the value is absolute) or relative values.<\/p>\n\n\n\n

For example, the value of relative humidity can be displayed very well, because this value is already relative and corresponds to a percentage value. To display absolute values you have to use a bit more \"mathematics\". Sounds complicated. But it is not.<\/p>\n\n\n\n

How you can show relative values on the display of your pxlBlck in loading bar optics is described in the following article.<\/p>\n\n\n\n
