Hello everyone, i am doing the Gyver Saber at the moment.
I have problems with the sound. I can connect 60leds and have the sounds and leds function and be controlled. But when i use 80leds or more the speaker stops displaying the sound of the Sd card reader.
I have already tried using an external power supply on all the components but that did not work.
Any ideas?
Arduino Nano ? Not enough memory issue likely. How much RAM do you have left when you compile?
Hi, @lightsaberproject
Welcome to the forum.
Do you have a DMM? (Digital MultiMeter)
Have you measured the Lipo voltage when the problem occurs?
Tom.. 
I have deleted your other cross-posts @lightsaberproject.
Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.
Repeated cross-posting can result in a suspension from the forum.
In the future, please only create one topic for each distinct subject matter. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
will do, and give an update
