Alle benötigten Bauteile, darunter ein speziell entwickeltes NodeESP-Board, sind in diesem Maker Kit enthalten es kann sofort losgehen!

Last but not least, you will find another programmable RGB-LED behind the door of the Advent calendar. Thus, we have two LEDs which you can interconnect to light your Christmas tree. We will need the following setup today. Setup of the Christmas tree light. The longer legs of the LEDs are on the right Activate the program and import the flow of today. Disable all previous flows and change the broadcast IP of the UDP node, if necessary. ...

The day before last reveals a tilt sensor behind the door of the Advent calendar. The sensor detects, if it is tilted. We will use it today as a sensor for an alarm system. The speaker from two days ago serves us as the signal generator. We will need the following setup. Alarm Setup As usual, activate the program of today and install the Node-RED flow into the environment. Also adjust the MQTT topic and disable all previous flows. ...

The door of day 21 reveals again a sensor, which we will use to measure the humidity level present. With the following circuit we will build a comprehensive indoor climate monitor. The indoor climate monitor circuit Our experiment today uses three sensors: the temperature sensor (NTC), the light sensor (photo transistor) and the humidity sensor. Altogether they deliver a real good impression of the current climate situation in a room. Let’s start the program of today. ...

The door of day 21 reveals a loudspeaker. We will use it in our experiment today to play some music. We will need a very simple setup for this. Setup In our experiment we will connect the speaker to one of the board’s two DAC outputs. DAC means digital/analogue converter and with this we can generate an analogue signal using digital commands. In our experiment today, we will use it to produce sounds, and to be more precise, we are talking about piano sounds. The notes, pauses and keys are sent via UDP by means of an array of numbers. ...

Behind the door is an NTC resistor (Negative Temperature Coefficient) that measures the temperature. Together with the photo transistor and a few wires, we are going to build a plant guard that alerts us, when a plant it is monitoring is exposed to bad conditions. We will use the following setup besides the program of today. The plant guard The two yellow wires are just simple wires that can be inserted into the potting soil. They are used to monitor the level of moisture in the soil. During our initial tests, we will just touch the two wires with a finger. ...

Today we have a very special LED waiting behind the door. It is an RGB LED with integrated controller (type PL9823, equivalent to WS2812) and with it you can now connect several LEDs in series and control them individually by means of a protocol. Today we will start by controlling one LED only. Here, an experiment that is almost customary in my Advent calendars fits in handy: the CheerLights project by Hans Schaaler. For all those who do not yet know the project: these are globally linked colourful lights which can be controlled simultaneously via Twitter commands. And here Node-RED fits in very well. The experiment today requires the following setup besides the program of today. ...

And today we have a small diode waiting behind the door. We are going to use the diode as temperature sensor for particular high temperatures and with it we will build a small candle guard. Breadboard Setup Today’s setup consists of the diode and the potentiometer, which we will use as a 10-kOhm resistor. This resistance is fixed and cannot be adjusted. The board will measure the voltage at the diode and sends the values to Node-RED via MQTT. ...

The door of day 17 reveals another potentiometer. Now we have one potentiometer for each LED and thus we will develop the program of Day 13, the Smart Lights, so that we will get a more convenient and intuitive dimming feature. We will also learn today how we can start timed events with Node-RED. Breadboard Setup Activate today’s program in the web interface. As always disable previous flows and change the MQTT topic to reflect your personal ID and then install today’s flow into the Node-RED environment. ...
