I read a lot on google, but I still can’t find the right anwser to my problem.
As a background:
I ordered an ambilight set which comes with a preconfigured arduino.
When I plugged everything in, the LED Strip blinked for a couple of seconds.
But not all of them.
So I started to investigate further, after the steps provided by the seller didn’t work.
I tried configuring everything with ambibox but couldnt get it to work.
At first when I chose static background, only 1/4 of all LEDs were working.
Now, not even one works anymore.
So I tried to investiagte furhter and openend the case, there was an Arduino.
I started to test the Arduino with the example programs from the IDE.
Was working perfectly eg. the Blink onboard LED test.
Still, I cant light my LED’s up. Not even one of them.
I guess something has to be wrong with the hardware, as no analog or digital pin is used.
How can this be? The cable just says data, but actually enters at the power supply. Please see pictures.
On one picture you can seee all the cables so here a little description:
1 Power supply coming from electricity wallmount to a splitter where the end and the start of the LED strip are connected. 1 male cable called “data” is going back to the Arduino and is plugged in at the power supply. 1 USB cable into the arduino and plugged in to my computer. Strangely, the USB provides the power and not the power supply from the LED Stripe.
I just find it strange, that there are no connection from pins, as every tutorial out there has that.
I really dont know, what I am doing wrong.
You can see the whole hardware configuration in the attached pictures.
Here is the link I bought it from:
Please dont judge I’m a poor student who wanted to have a holiday project I study Business Information Technology, so I should be able to understand the sketches.
Thank you very much for your reply in advance and happy holidays
