You can also conduct the blue LEDs with the white LEDs at an outlet. You cannot connect the red and the white LEDs, also not the yellow and the red LEDs. These LEDs cannot be
conducted together at an outlet, but only at separate outlets or through separate series resistances. The cables can also be lengthened. So you can light more buildings with a building
lighting.
Why is it like that? What’s the reason?
The different colors of the LEDs cause a different physical structure. The emissions of higher energy photos require a different semiconductor material. Because of that, the so called
forward voltages of the single LEDs are different. Starting with this voltage the LED lights: Red LED 1.6 volts / yellow LED 2.0 volts / blue and white LED 3.6 volts.
How to improve the visual effect?
For this, you should be based on the real world. Windows own so called reveals. That means: usually there’s a certain distance between window glasses and the curtain in the reality. Of
course, the versed modeler can install it also into a lightened house. Therefore you cut a slightly thicker cartoon in the size of the window and set it between the curtain and the window
glasses. So, a beautiful depth effect results.
If you want that the light in the window lights very brightly, you can line the light well with aluminum foil. Because of the reflection of the aluminum foil a mirror effect results, which
reinforce the visual effect. It is particularly necessary to ensure that the aluminum foil does not short the LED contacts.
Finally something for the perfectionists and the experts.
By turning on, the outlet L1 flashes briefly. That’s because the microprocessor needs some milliseconds to start the program. If you want to avoid this effect, you can reach this by
using a parallel connection of an electrolytic capacitor (not included) with the worth of 100 μF/25 V in parallelism to the connected LEDs. Pay attention to the polarity of the electrolytic
capacitor.
What should you avoid by using the Interior Lighting for Buildings?
Please avoid that the railway circuit has a a direct contact with the LEDs and the control. Any type of short circuit must be avoided. Solder carefully!
How can you interconnect the other E-Kits with the Interior Lighting for Buildings?
First, the E-Kit “Twilight Switch” (purchase order number 60271) is very suitable to switch the Interior Lighting for Buildings dependent on the daylight. After the nightfall, one or
more buildings “come to life” Therefore the Interior Lighting for Buildings won’t be connected directly to the power, but the electric power supply will be turned on and off by the relay.
Of course, more than one Interior Lighting for Buildings can be connected to the Twilight Switch. Up to 10 Interior Lightings for Buildings can be connected. Five to the top of the relay
contact and five to the bottom of the relay contact of the twilight switch. Also the E-kit “Light Barrier” (purchase order number 60272) can be interconnected very well into the Interior
Lighting for Buildings. If the Light Barrier will be triggered, e.g. a whole district comes to life. Also more Interior Lightings for Buildings can be triggered by different Light Barriers.
That’s a really great effect.
Where can I show my own installation of the e-kit?
www.mymocom.com is a platform for all model railway enthusiasts. There you can share your own ideas how to apply the Interior Lighting for Buildings to one or several houses.
How does the circuit (hardware) work exactly?
The circuit consists of:
• Microprocessor
• Power supply system
• Entries and outlets
The microprocessor operates the stored program (software) line by line and so it can check the entries and regulate the outlets (LEDs).
The central element is the microprocessor. The detector, the capacitors and the voltage regulator insure a reliable power supply of the microprocessor. The small components with the
sign are resistors which are soldered on the board for the single entries and outlets of the microprocessor. Thus a relay can be connected by the microprocessor; one transistor of the
circuit board is present.
What are the special elements of this microprocessor?
Every microprocessor has to be supplied with a pulse for implementing the program. For this, a lot of computers use an extern oscillating crystal. But this small micro computer has
installed a small intern pulse generator. All things which are needed for a solution of a simple control task are implemented in only one computer chip. You only need to know 33 com-
mands to code a microprocessor.
How does the saved program (software) work exactly?
First, the computer tests the entry SW. Here, it’s tested, whether the first or the second program will be used. Then, the outlets will be turned on or off according to a given time and
order. The flickering of the TV is achieved as well. Here, the time series, in which the outlet LO will be turned on and off are chosen shorter. The times for the activation or deactivation
are of different lengths. So, the impression of flickering arises. After 20 times flicker, the subroutine “TV” begins again. Hardly any human perception would be able to recognize this
sequence as a repetition. This creates the impression of randomness.
Where I can find further information?
The manufacturer of the chip is a good resource to learn more about the microprocessor which is used here. On the website www.microchip.com you will find something quickly by
searching the used microprocessor. Enter “PIC10F200” in the search box “Search Data Sheets”. The data sheet of the microprocessor comprises approximately 100 pages. Here the
small microprocessor is described in detail.
