Hello, I'm rather new to the field of electronics apart from some Arduino basics. But I'm a "never tried before so I guess I should be able to" kinda guy and I like to set myself a challenge to learn new skills.
Currently I'm working on an Arduino controlled flea circus. I designed and 3d-printed all the mechanics and now I'm starting on the electronics part. I decided to start with the 'easy' bit of making a circle of LED's.
I made an array of 17 Flickering (yellow) LED's. 2.2V, 20mA with a switch and a 9V battery.
The calculator came up with a Parallel setup of 5 times 3 LED's in SERIES with a resistor and a single branch with 2 LED's + resistor.
And after testing, soldering everything, testing again and pruning all the sticky out bits, testing again, fixating everything with hot glue ...Riding to my holiday location I just realized I messed up (wanted to get it done before leaving on holiday ... Never a good idea ) and put the LED's in the branches in parallel to each other (but still in series with the resistor).
Is this going to pose a problem and what would the effects be?
My basic understanding of Ohm's Law makes me guess each LED will get more Voltage than needed and less current. Resulting in less brightness, which isn't a problem since it's meant to be decorative mellow fire anyway.
So maybe it's a happy accident. But maybe I'm missing something important and I'd rather be safe than sorry.
(And I'd prefer not having to pull everything back out, buy new LED's and start over if it isn't needed).
Thanks in advance for your kind advice.
If needed I'll try to post up some schematics, bit difficult to do on my phone at the moment.
