Hello, I just recently registered on the forums, so first of all, Hi there! Now to my question. I am making a 9x9 Green LED panel for a project. I do not know anything at all about electronics(The bad news) but I have the necessary tools to do the project. Goal: Make a 9x9 LED panel that pulses to the beat of music.
For the LEDs to flash to the music I am using a Tip31 transistor. I already made a working small version with 3 leds, each one in parallel with a 9v battery, but no resistors on them. I used the LED parallel calculator i found on the internet but i dont know how many batteries to use and also I dont know if this mockup I made would work.
The 9v batteries are the rectangular ones found in clocks, radios, etc. I found the image of the original LED Music schematic and combined it with the Calculator image. This is meant to be portable so any advice whether it will work or not is appreciated. The LEDS are 3.0-3.2 VF, IF:20mA
