This module of the RaylFX system<\/a> can be used to illuminate a settlement, a building or a city. Up to ten residential buildings can be illuminated. In addition, there is an LED that simulates a TV, street lighting with two channels that light up at night, one channel that flickers and two channels for one or two billboards that either alternate or flash differently from each other.<\/p>\n\n\n\n

Wiring Diagram<\/h2>\n\n\n\n
\"RaylFX<\/a><\/figure>\n\n\n\n

This module also works with an Arduino Nano. LEDs are connected to the digital channels 2, 3, 4, 5 and 12, 13, 14 (A0), 15 (A1), 16 (A2), 17 (A3) as residential lighting. Each channel can supply up to 40mA. Additional LEDs can be connected here in parallel to the current LEDs. They then all share one resistor. However, the luminosity of the individual LEDs is reduced. In addition, the LEDs in the respective parallel circuit must be the same (same internal resistance), otherwise only the LED with the smallest internal resistance will light up. At pin 6 a LED is connected, which flickers and should simulate a TV. In my case it is green because football is on.<\/p>\n\n\n\n

The street lamps are connected to pins 10 and 11. Additionally there is a connection for a flickering, defective street lamp at pin 9. With these pins you could also realize a motel lighting, in which a letter flashes (known from motel signs :-D)<\/p>\n\n\n\n

Pins 7 and 8 can illuminate billboards. They can be set so that they do not flash, flash alternately or flash at different speeds. This can be used to illuminate advertising banners above stores, or to create animations with two phases and so on. Here I could imagine engraved acrylic glass panes, which are illuminated from the edge by LED.<\/p>\n\n\n\n

Attention: The control signal of the RaylFX control module<\/a> is applied to pin A4. It controls the time of day and is mandatory.<\/p>\n\n\n\n

Code Settings<\/h2>\n\n\n\n

Like all RaylFX modules, this one is also controlled by the control module. It provides the time and thus synchronizes all RaylFX modules.<\/p>\n\n\n\n

Several settings can be made in the code.<\/p>\n\n\n\n

The variable streetlampTimeout controls the switch-on time of the street lamps in milliseconds. These then dim themselves in the specified time.<\/p>\n\n\n\n

With the variable streetlampFlicker <\/em>the flickering frequency can be set. The higher the value, the slower the LED flickers at pin 9.<\/p>\n\n\n\n

The residential building lights should switch on and off differently, so that the settlement also looks nice and lively. This can be influenced with the variable switchonLikelihood<\/em>. The higher the value, the more displaced the houses switch on. The same for switching off is done by the variable switchoffLikelihood<\/em>.<\/p>\n\n\n\n

Now some advertising: The variables adBlink1 <\/em>and adBlink2 <\/em>control the LEDs for the advertising panels. If the value of both variables is the same, they blink alternately. This could be used for an animation. If the value is different, they blink in independent frequencies. So here, for example, two independent advertising boards can be operated. If the value is set to 0, the LEDs light up permanently.<\/p>\n\n\n\n

int streetlightTimeout = 100;           \/\/ switch-on time of the street lights (ms)\nint streetlightFlicker = 1000;          \/\/ the higher the value, the slower the LED flickers at pin 9\nint switchonLikelihood = 2000;          \/\/ the higher the value, the more displaced the residential lighting will turn on\nint switchoffLikelihood = 2000;         \/\/ the higher the value, the more displaced the residential lighting will turn off\nint adBlink1 = 1500;                    \/\/ flashing speed of the advertising LED, 0 = do not flash\nint adBlink2 = 1500;                    \/\/ flashing speed of the advertising LED, 0 = do not flash<\/code><\/pre>\n\n\n\n
When uploading you have to make sure that the correct board is selected in the Arduino menu. To do this, “ATmega328P (Old Bootlaoder)” must also be selected in the Processor subitem of the Tools menu.<\/p>\n\n\n\n
The following program code can be easily copied with the above mentioned changes and loaded onto the Arduino nano.<\/p>\n\n\n\n
