I've been trying to connect my LED stripe -> rgb amplifier -> Arduino Mega 2560 -> PC. After connecting it according to this guide, nothing happened.
Looking inside the amplifier I noticed the three 5.1V Zener diodes. Using a multimeter I discovered the 5V from my Arduino only carries ~3.8V to those diodes and it consequently stopped there. Shorting out either diodes made my lights glow (and it only took me a few hours to get to that point..).
Now it seems I have two options:
- Sending it back and order another one which hopefully uses different diodes
- Using a soldering iron and short them out myself
Is the later even an option? Are there any safety issues?
Is there something else I can do?
