Simple directional light electronic scintillator based on 555

0805RGB flashing

Shenzhen excellent micro led lamp bead manufacturers 5mm colorful flash short foot self-flashing bead LED

PESD1CAN electrostatic protection SOT23-3 24V two-way

Probe orientation needle 265*2980 needle head diameter is 6.0 end probe needle

As shown in the figure, the scintillator consists of a 555 oscillator and driver. Compared with the thermal relay scintillator, it has the advantages of low cost, strong adaptability of the power supply voltage and high reliability.
In this circuit, 555 and R1, R2, and C1 form an astable multivibrator with an oscillator frequency of about 1 Hz. The VMOS type K75 tube is used as a drive switch. When the car turns left or right, it will be left or right. The indicator light is on and lit.
