This is a blinking light circuit power by the energy of the sun.
Utilizing a solar panel to convert the suns energy two LED�s will alternatively blink and the blinking speed may be adjusted.Technical Specifications:
•Power Source: Solar panel
•Solar panel: 4 VDC, 60 mA
•Adjust flashing speed with potentiometer
•PCB dimensions: 1.39 x 1.27 inches
Operating Principles:
TR1 and TR2 form a multi vibration frequency circuit when assembled and work in conjunction with LED1 and LED2 to alternatively turn the LED�s on and off.
When TR1 is powered, LED1 will light and LED2 is off.
When TR2 is powered, LED2 will light and LED 1 is off.
The blinking speed is controlled through VR10K, R2, R3, C1 and C2. R1 and R4 act to reduce voltage to the LED.
