The circuit is based on an analogue oscillator and arrow of LED's.
The oscilator use four pieces, and the arrow ten pieces.
Lock the pictures.
Step 1: Take the Parts
Q1 - 01 transistor BC 548 (NPN, general use, silicon)
Q2 - 01 transistor BC 558 (PNP, general use, silicon)
D1,D2,D3,D4,D5,D6,D7,D8,D9,D10 - 10 Common LED red, yellow or green (I use the red)
R1 - 01 resistor, 1 megaohm x 1 / 8 w
C1 - 01 to 10 microfarads electrolytic capacitor x 16 V
B1 - 02 cells in series with low-battery.
Step 2: Finish
-mount the arrow on a separate card if you use as flag
-mount the arrow on the plate if using as a flag in hand.
-use high-brightness LED's for better signs.
The assembly and simple, and hard mistake. If you have problems, send an email to firstname.lastname@example.org so I can help you, and send your tips and modifications. until the next. Bye!
