Hello, I'm relatively new to electronics so I apologize if my questions are a little bit basic.
Now to the project. I have a break light for my bike with 4 LEDs (see picture). First I would like some help to draw the circuit diagram based on the printed circuit board and the picture to identify the components. I've numbered some elements that I've identified in the picture:
1)switch that goes to the bicycle brake
2)BC547B - NPN transistor
3)22 microF capacitor
4)22 Kohm resistor
5)27 ohm resistor
6)1N4148 diode
Numbering the LEDs from left to the right 1 2 3 4, one can see that LEDs 1 and 2 are blinking alternately and so are LEDs 3 and 4 when all the LEDs are on. When I brake (or push the switch) they all start to blink together.
So what I would like to do is to modify the circuit to have all LEDs on at the same time and when I brake they brighten up a little just like a automobile break light.
Thank you in advance,
Gabriel
