Title: [Help] build the matrix led with transistor
Post by: alaterlight on January 27, 2012, 01:14:40 AM

construction matrix LED with transistor, capacitor, resistor, ... not be used microcontroller (IC) circuit diagrams for me. thanhk

What do you need transistors and caps for? What do You want Your LED matrix to do?

I intend to do with flashing lights transistor without using the microcontroller. it is difficult. I do not know how to control the lights without a microcontroller

What you want to control? the circuit will flashing the LED lights using transistors. what else you want to control?
We did not learn mind reading, do not know what is in your mind.
