I have a question, in this video you can see 8 LED's, and two led's of each color is connected to the one pin, so my question is how do you make it blink, because you can see in the video first led activate then the it turns of and then other one which is connected at the same pin as first led starts to illuminate
I know that PIC is programmed, is there any command for that or how is it connected ?
I suspect the two LED of the same colour are connected in reverse.
The drive polarity is then reverse to light each LED of the pair individually.
The overall lighting of the LEDs is controller at a much higher rate than you can see, making use of multiplexing and perception of vision to create the effect you see.
