What kind of Instruments Against Darkness types are there!


7/2019. First setup

First setup in four steps.

After connecting the power supply to the IAD, you need to connect the IAD to your WiFi by setting up the correct data.

Lookup in your wlan list for the IAD and connect to it.

Type in your browser the IP. nr:

Select the configure WiFi button in the WiFiManager.

Enter the correct data and save it.

The IAD is part of your network so what is next.

Connect with A PC using MDNS.

Connect with mobil using the ip address.

Connect with Node-RED.


7/2019. Manual guide

As an access point.

After powering up the IAD,
take your mobile and turn on WiFi.

In WiFi settings, scan for a hot spot with the name “AD3D IAD..”.

Connect to it with password “12345678”.

After connecting to "AD3D IAD.." hot spot,
open a web browser in your mobile phone
and enter IP ""

Now you will see the IAD webpage.

Important Note:

Android OS does not support mDNS.
You have to use an IP address on a mobile phone.
To solve this problem, the IP address is printed on the info web page.
(see As an access point to recieve this IP)

Connected to an access point.

After connected to your Wifi network, open a web browser in your mobile phone and enter the IP Nr.
(see As an access point to recieve this IP)


Open a web browser on your local computer and enter the IP that's provided by your network, found on the webpage.
(see As an access point to recieve this IP)
Or enter it's name, like “IAD05.local”.


6/2020. Effect

Color is a powerful communication tool and can be used to signal action, influence mood, and even influence physiological reactions.

Certain colors have been associated with increased blood pressure, increased metabolism, and eyestrain

Your feelings about color are often deeply personal and rooted in your own experience or culture.

What is what

What is a WiFI

A wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication. Here's what happens: A computer's wireless adapter translates data into a radio signal and transmits it using an antenna. A wireless router receives the signal and decodes it. The router sends the information to the Internet using a physical, wired Ethernet connection. The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter.

What is a LED

In the simplest terms, a light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is produced when the particles that carry the current (known as electrons and holes) combine together within the semiconductor material. Since light is generated within the solid semiconductor material, LEDs are described as solid-state devices. The term solid-state lighting, which also encompasses organic LEDs (OLEDs), distinguishes this lighting technology from other sources that use heated filaments (incandescent and tungsten halogen lamps) or gas discharge (fluorescent lamps). Different colors Inside the semiconductor material of the LED, the electrons and holes are contained within energy bands. The separation of the bands (i.e. the bandgap) determines the energy of the photons (light particles) that are emitted by the LED. The photon energy determines the wavelength of the emitted light, and hence its color.

What is mDNS

In computer networking, the multicast DNS (mDNS) protocol resolves host names to IP addresses within small networks that do not include a local name server. It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as the unicast Domain Name System (DNS). The mDNS protocol is published as RFC 6762, uses IP multicast User Datagram Protocol (UDP) packets, and is implemented by the Apple Bonjour and open source Avahi software packages.

Access point

An access point is a device that creates a wireless local area network, or WLAN, usually in an office or large building. An access point connects to a wired router, switch, or hub via an Ethernet cable, and projects a Wi-Fi signal to a designated area.

Hot spot

Wireless hotspots are wireless access points, typically in public locations, that provide network/internet access to mobile devices such as your laptop or smartphone when you are away from the office or your home. Typical Wi-Fi hotspot venues include cafes, libraries, airports, and hotels.
