I am sure that you get a lot of questions about basics on LED diodes so I will first apologize and then ask.
Okay,last year I bought some cheap Chinese LED lights for a Christmas tree. Now I would like to make something else out of them now.
The whole device is powered by 3x1.5V batteries (4.5V) and its connected to 20 LED diodes (red,green and yellow) in parallel circuit. It has a simple switch (on/off) and it has a resistor right after the switch (brown-black-black-gold (I guess its 10 ohm,correct me if I am wrong)) and the every second (starting from first one) LED diode has an smaller resistor (brown-green-brown-gold(guess-150ohm)).
The thing is that I don't know what LED diodes are these because they does not look like the ordinary LEDs,instead of rounded top they look kinda like this,this shape and size but these don't have the bottom wider then the rest of the LED,its all the same width like this.
I would like to make the same circuit only with 14 LEDs on the same source (4.5V).
Can you tell me why is there a resistor on every second LED? (it's kinda weird)
And what type of LEDs are these? Never seen them like this.
I look forward to your answer.
Thank you.
