To be used in any project where a blinking light is needed, mostly useful for RC model aircraft, rc cars, or any scale model. It's extremely small size makes it perfect to fit in any small project, the time of blinking can be adjusted with potentiometers, on time as well as the period time is adjustable, it can be powered with 9v and you'll have an output where you can connect LEDs or relays for bigger loads.The project uses SMD components for a small size and light weight.The components to be used are as follows: 555 timer (SO8)x2 trim potentiometer 3mm-2 500KLED 0805100nF cap 08051uF cap 080510uF cap 1206X2 150 ohms resistor 0603Diode SOD 323PNP transistor SOT 23Pin Headers
