Question by Ash

21st May 2012

QHi, I am doing a school D.T project, I was going to use 4 AA batteries and 5 LED's and wire the LED's up in a parallel circuit. Will this work?

AHi Ash, thanks for your question. Yes this would work.

Question by Ash

QHi, can you put eight of these into a paralel circuit? and if so how many volts will i need? Thanks

APutting 8 of these LEDs in parallel is fine. This will just require 5 volts each.

Question by R

QHow many of these can you run in series off a 9v battery?

AHi R, thanks for your question. You can only run 1 in practical terms since as it changes colour it changes to another colour chip – and interrupts the signal very slightly – which would affect any others in series with it. Even at best it would only be 2 max and not very well as it really requires 5V each – but might get away with slightly less.

QAre these led's good for working off a pic or picaxe chip? Could you put two in parallel off such a device.

AHi Ian, thanks for your question. This will be fine for your requirements.

QCan this LED be connected directly to a battery or is a protecting resistor required? Would the LED work adequately with just 3v or are three cells needed (ie 4.5v)? Any idea roughly how long the LED would work from a couple of AA batteries?

AThanks for your query, This product will work at 3 volts but really requires a 5v battery. Product life will depend on the ah rating of the battery

Question by Will Burns | Product code: 55-1906

23rd November 2011

QWhat is the time in seconds for the LED to cycle through all 3 colours? The catalogue says it cycles at 1.5Hz, but the 3mm and 10mm LEDs have cycle times of >30s. 1.5Hz seems a bit quick!

AThe cycle time for all 3 colours is 30-40 seconds MAX.
