Question:

I am a primary school teacher and I set my year 6 girls a task of making an electrical toy with a motor lights and sound if possible. I get a lot of lighthouses roundabouts etc but many now request coloured LEDs. I have made some of your zippy toys over the years and those colour changing LEDs do not seem to need resistors but the coloured ones seem to come up odd colours or burn out so could I have some advice please. For example one girl wants to do a mr McGregor's garden with eight small orange LEDs and eight larger green ones. What resistors would I need to get? Can they be wired in parallel off two 1.5V cells?

    Hi Sally, 

    The colour changing LED’s don’t require a resistor, however the standard colours do. Depending on the voltage you are using and the number of LED’s in parallel will depend on the resistor.

    https://www.kitronik.co.uk/blog/led-resistor-value-calculator/ if you use our resistor calculator it will help you to find which resistor is best. If you are still struggling please contact me on support@kitronik.co.uk. In regards to using two 1.5V coin cell batteries wouldn’t be able to run that many LED’s. Using our 3V coin cell batteries you could run around 4-5 LED’s in parallel.

Question:

Would polarity protection diode be required in a battery powered LED circuit. Specifically x3 5mm white LED's x3 AAA batteries. Thank you

    I don't think it would need one. The LEDs are diodes themselves and the reverse breakdown voltage of most of our LEDs is 5V so I think you'd be fine without one.

Question:

does it come with resistors

Answers:

  • Posted by Geoff Hampson on Monday, 28 November 2011
    You would need to add a current limit resistor, as this is not supplied with the kit. The value of the resistor will depend on the voltage that you are using. If you look on the resources page we have a hand little resistor calculator that will tell you what resistor to use for a given LED at your chosen voltage.

Question:

Hello What Voltage Are They ?

Answers:

  • Posted by Geoff Hampson on Monday, 26 September 2011
    All the LEDs in this kit have a forward voltage of around 2V.
