Hello all and good evening!
i found this forum whilst frantically searching the internet for help with a university project that i have undertaken, needless to say i am an electrical novice with very little wiring knowledge!
i am currently in the middlle of building an array that consists of
9 yellow LED's
1.8 - 2.2 forward voltage
30mA forward current
24 Blue LED's
3.2 - 3.8 forward voltage
30mA forward current
56 Red LED's
1.8 - 2.2 forward voltage
30mA forward current!
the power supply i have is
5V output 0.2a
to begin with is this suitable?
secondly
i assume this quantity will require parrallel wiring but i have no idea what colour LED's to start with and where to place resistors of what value to ensure that it all works!
i know this is a big ask but is there anybody that understands me and if possible could point me in the right direction
i have tried LED calculators but didnt believe they would work due to the Blue LED's having a higher forward voltage!
regards
Jay
