8Hi
My son has attempted to make / built the (mini kit) Xmas tree with 16 LEDs which he has
But only LEDs1/2/3/4 and 13/14/15/16 are working and the lights are on all the time
As you know once its build it’s difficult to see were he when wrong
I am sure you could work it out from the circuit diagram from what is working what he has assembly incorrectly
Looking at the instructions the transistor can only be fitted one way, the elco look the correct way round
The LEDs may or may not be the right way round, so it may be a resistor problem
Please can you help?
If not we may have to by another kit and I will assist him in building it
Regards
Tony
