I have bought some of the following LEDs (going to try either for brightness/size):
- 100 Pcs 0603 SMD Superbright LED Yellow Light Emitting Diodes
- 40 Pcs SMD 1206 LED Lamp Yellow Light Emitting Diodes
I wish to arrange them in three groups of five as shown in the attached block diagram. The idea is there would be three separate strands going off in three directions, each with five LEDs on.
What would be the best arrangement to connect in this way (series or parallel) and also what is a suitable value for the current-limiting resistor for these LEDs, how many and where should they be placed? Also what would be a suitable battery to use - should I go for a PP3 or will a couple of AA's be suitable?
I would appreciate a circuit diagram if someone can help please!
