100k ohm valued resistor and 10uF valued capacitor determine blinking time interval of LEDs. In order to drive the output first know the current requirement of your output if it requires approx 600mA current then a normal BJT will do the job but when it comes to drive high power ouput devices such as high power led which requires about 1A current then you have to go for Darlington Pair NPN BJT Transistors. Transistors With Arduino (BJT) - BC547 TIP120 By electronicGURU in Circuits Arduino 25,066 7 4 Download By electronicGURU electronic GURU Follow More by the author: About: I am an engineering student and i just love doing electronic (mcu's) and programming (C,C++,JAVA) based projects. 2x BC547 NPN type BJT transistor 2x 10uF/25V capacitor 1x Green LED 1x Red LED Description: The leds color is not essential you may use diffirent colors such as yellow, blue, white etc.
