On the Blynk interface, you see two ZeRGBa elements, which are labelled &#8220;DayLight&#8221; and &#8220;NightLight.&#8221; When you switch to day or night mode with the outside buttons below the ZeRGBa elements, the corresponding colour of the element is shown. But you can also automate the switch between day and night mode. To do this, tap one of the two timer elements directly below the colour selection elements. Here, while the interface is not started, you can select a time at which the mode should be switched. All you have to adjust is the start time. The same applies for the other timer element. At the selected time, the mode switches over, and the LED changes from the day colour to the night colour or vice versa. You don&#8217;t even have to have the app open at those times. The Blynk server regulates the switch-over automatically.<\/p>\n<p><div id=\"attachment_1354\" style=\"width: 288px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day11_3.png\"><img aria-describedby=\"caption-attachment-1354\" decoding=\"async\" loading=\"lazy\" class=\"wp-image-1354\" src=\"http:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day11_3-576x1024.png\" alt=\"Die Oberfl\u00e4che des Tag\/Nacht Lichts\" width=\"278\" height=\"494\" srcset=\"https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day11_3-576x1024.png 576w, https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day11_3-169x300.png 169w, https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day11_3-768x1365.png 768w, https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day11_3-972x1728.png 972w, https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day11_3.png 1080w\" sizes=\"(max-width: 278px) 100vw, 278px\" \/><\/a><p id=\"caption-attachment-1354\" class=\"wp-caption-text\">The user interface<\/p><\/div><\/p>","protected":false},"excerpt":{"rendered":"<p>Behind today&#8217;s door is a 10-kohm resistor, but we don&#8217;t need it yet today.
