For example, if you push the first button in the app, the LED at D9 starts to light up. The second button switches on the LED D3, which is permanently mounted on the board. With the button on the breadboard, you change the status of the first app LED. You can affect the brightness of the second LED with the potentiometer. Thus you have many different control options for many different elements.<\/p>\n<p><div id=\"attachment_1336\" style=\"width: 275px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day8_2.png\"><img aria-describedby=\"caption-attachment-1336\" decoding=\"async\" loading=\"lazy\" class=\"wp-image-1336\" src=\"http:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day8_2-640x1024.png\" alt=\"Die heutige Oberfl\u00e4che\" width=\"265\" height=\"424\" srcset=\"https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day8_2-640x1024.png 640w, https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day8_2-188x300.png 188w, https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day8_2-768x1229.png 768w, https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day8_2-972x1555.png 972w, https:\/\/iot.fkainka.de\/wp-content\/uploads\/2016\/09\/Day8_2.png 1200w\" sizes=\"(max-width: 265px) 100vw, 265px\" \/><\/a><p id=\"caption-attachment-1336\" class=\"wp-caption-text\">Today&#8217;s user interface<\/p><\/div><\/p>","protected":false},"excerpt":{"rendered":"<p>In the test for the sixth day, you saw how a push button on the hardware side can be mapped on a button in the app. However, another widget, namely the LED widget, is much simpler for this instance.
