ZEDCON - Töne zum Leuchten bringen

Turn sounds to lights 

In the two previous posts we have seen how to connect an LED strip or an LED matrix to the ZEDCON and how to configure the ZEDCON. In this post we will now look at the feature that sets the ZEDCON apart from other LED controllers. The ZEDCON has a built-in microphone and alternatively an audio input with a jack plug. Audio signals entering the device through either of these inputs can affect the LED display. How this happens can be configured.

The microphone is located on the front of the device.

 


The audio input is on the back next to the connections for the LEDs. If a jack plug is plugged into the socket, the microphone is switched off. A cable with two jack plugs is used to connect to an audio output (smartphone, iPod or similar). However, if you also want to connect an amplifier or headphones, you need a Y-cable with two sockets and one plug.


For the configuration we need the Zedcon app again. How to install these and how to make the basic settings was in the first and second Part of this series explained. Again we use the 8x8 LED matrix from AZ-Delivery.

BUMP operating mode

 

In this mode, each volume fluctuation switches to the next color. All LEDS have the same color.

With COLOR the colors to be applied can be selected. Since this operating mode switches between different colors, the selection of a fixed color makes no sense. For the heart symbol, the colors are selected from the list of preset colors. For the next symbol, random color values are used, and finally, for the rainbow symbol, the colors from the rainbow are used.

With SENSITIVITY the sensitivity is set. The further to the right the slider is, the higher the sensitivity.
With FREQUENCY OFFSET the frequency range to which the device reacts can be set. If the slider is on the far left, the range is from about 1.2 kHz to 3kHz. If the slider is all the way to the right, the frequency range is from about 400 Hz to 1.2 kHz.

STROBE operating mode

 


In this mode, the brightness is influenced by the volume. All LEDs have the same color. Either a fixed color is used or the colors are continuously interchanged. This depends on the selection at COLOR.

FADE SPEED is used to set how long the LEDs will fade.
COLOR TIME sets how much time elapses between a color change. Far left = maximum, far right = minimum.
SENSITIVITY sets the sensitivity. The further to the right the slider is, the higher the sensitivity.
With FREQUENCY OFFSET the frequency range to which the device reacts can be set. If the slider is on the far left, the range is from about 1.2 kHz to 3kHz. If the slider is on the right, the frequency range is from about 400 Hz to 1.2 kHz.
With INVERSION the function can be reversed. No sound gives full brightness. Depending on the volume, the LEDs become darker.

EQUALIZER mode

 


In this operating mode, the audio signal is divided into frequency groups. Each LED in the X direction is assigned a specific frequency range. The height of the LED bar corresponds to the volume of this frequency range. Additionally, the maximum of the volume is held for a certain time. The rainbow is always used as color. This means that one color is assigned to each frequency range.

With PEAK SPEED you can set how long the maximum value should be held. Far left = maximum and far right = minimum.
COLOR TIME does not influence the display.
With SENSITIVITY the sensitivity is set. The further to the right the slider is, the higher the sensitivity.
With FREQUENCY OFFSET the frequency range to which the device reacts can be set. If the slider is on the far left, the range is from about 1.2 kHz to 3kHz. If the slider is all the way to the right, the frequency range is from about 400 Hz to 1.2 kHz.
INVERSION reverses the behavior.

SPARKLE operating mode

 


In this mode, all LEDs are controlled with half brightness. As with the EQUALIZER, the audio signal is divided into frequency groups. Each group is assigned an LED column in the X direction. The volume per frequency is not displayed as a bar like with the equalizer. In this mode, only the maximum value is displayed by the corresponding LED changing to full brightness, creating a glitter effect.

With COLOR the color of the LEDs is selected. With the fixed color, all LEDs are permanently controlled in this color. With preset colors and random colors, the color changes continuously, and the display duration for a color can be set with FADE SPEED. Far left means maximum and far right means minimum. With rainbow, the rainbow colors are displayed line by line from top to bottom and do not change.
With SENSITIVITY the sensitivity is set. The further to the right the slider is, the higher the sensitivity.
With FREQUENCY OFFSET the frequency range to which the instrument reacts can be set. If the slider is on the far left, the range is from about 1.2 kHz to 3kHz. When the slider is all the way to the right, the frequency range is from about 400 Hz to 1.2 kHz.
INVERSION does not affect the display.

The SPECTRUM and DIRECT CONTROL operating modes have no function in the current version of the firmware.

Summary

Now that we have shed a little light on all operating modes and their settings, nothing stands in the way of your own experiments. The controller simply controls the LEDs one after the other, so you can achieve interesting effects by incorrectly specifying PIXEL AMOUNT and PIXEL HEIGHT. Only the product of PIXEL AMOUNT and PIXEL HEIGHT should correspond to the total number of LEDs.

In this short video you will find more information about these features of the Zedcon controller:



Have fun trying out the these effects.
