NanoESP

Auch dieses Jahr gibt es wieder die Vorabversion aller Programme zum Ausprobieren. Wie bereits in dem Handbuch erwähnt wurde speziell für den letzten Teil des Adventskalenders ein eigener Server gemietet und konfiguriert. Dieser ist nun soweit eingestellt, dass auch die letzten Versuche funktionieren. Es kann allerdings immer noch sein, dass es bis zum offiziellen Start im Dezember zu kurzen Downzeiten kommt. Ein Problem gibt es derzeit noch mit dem Cheerlights Projekt am Tag 23. Ich hoffe, dass ich dieses Problem in den nächsten Tagen lösen kann. ...

Das Adventskalender Projekt vom letzten Jahr hat anscheinend viel Anklang gefunden. Anhand der Nutzerzahlen konnte ich ablesen, dass viele Interessierte täglich den neuen Versuch auf der Webseite aufgerufen haben und auch in den Kommentarbereichen war ordentlich was los. Es war einfach schön zu sehen, wie Sich viele verschiedene Bastelbegeisterte gegenseitig helfen. Aus diesem Grund soll auch in diesem Jahr das Adventskalender Projekt durch diese Webseite begleitet werden. In dem letzten Jahr war der die online Unterstützung ein erster Versuch, der anscheinend recht erfolgreich war. Dennoch gab es einige Kritikpunkte, die teilweise auch Ihre Berechtigung hatten. Deswegen habe ich versucht in diesem Jahr einige Dinge besser zu machen. ...

The final project consists of several elements you have been introduced to in the course of the advent time. One function is the Cheerlights function presented the day before. You can also receive the current colour of the Cheerlights project and display it with the RGB-LED. The board is also used for long-term monitoring of the temperature. At the same time, the board is used to emit an alarm sound when the temperature exceeds a specific value, e.g. because there is a fire. As a last function, the board can be used as a Christmas bell, by making it play the song Jingle Bells with a time-controlled TalkBack command. All in all, today’s project is an all-rounder for the Christmas tree. ...

Today’s experiment is based on a project by Hans Scharler that is called Cheerlights. The idea is globally linked lights that can be simultaneously controlled via Twitter commands. It is a good example of the world growing closer and closer together with the Internet. The circuit is similar to previous projects Behind today’s door, you will find a fourth extension cable with which the RGB-LED can also be placed aside. This can be particularly practical if, for example, you want to hide the board in the Christmas tree while the RGB-LED decorates the top of the tree. ...

Today’s project is about another app of the ThingSpeak page, i.e. the TalkBack-App. This function permits creating a command that is read and executed by the controller. What appears nonsensical with a single controller does make sense when using two or an entire network of controllers. Some boards can act as sensors then, e.g. with motion detectors, and send a TalkBack command. Another module reads the command from the ThingSpeak page and then opens the door or reports an alarm. ...

Today’s project is an alarm system with which you can, for example, check whether someone opens a drawer without permission. There is a continuous check for whether the connected light sensor is exposed to too much light. If this is the case, an alarm signal will sound and a message will be sent via Twitter. Lightsensor on A0 and Piezo on D8 Behind today’s door, there is a Piezo speaker that is used as alarm signal encoder. The structure of today’s experiment is shown in the figure. ...

The website ThingSpeak offers a lot more than just long-time monitoring of sensors. Today’s project is similar to the projects from days 9 and 10 in its basic idea. Information is collected from a website on the internet. In this case, it is whether a specific stream is currently online or not. There are two decisive advantages of the ThingSpeak version over the first attempts. First, the ThingSpeak page can also call websites via HTTPS (HyperText Transfer Protocol Secure), while the module only supports the unsafe HTTP-protocol. Second, the website can pre-filter important information and thus clearly reduce the data volume to be processed by the controller. ...

In the last days of the advent time, we will deal with an entirely new subject: the website ThingSpeak. This website has been specifically developed for the subject of Internet of Things and contains various practical functions for you. Before you tackle the setup and programme as usual, you need to set up an account on the website www.ThingSpeak.com Log in with your user data under the item Sign In. You can see a website that shows your channels. Since you have no channels yet, this site will look rather empty. Click New Channel and assign a name, e.g. Light. In this project, you will measure brightness. In the item Field1, you can now assign a name to the field, e.g. Brightness. All other fields can be left empty for now. ...
