The HT212 is a 16 LED Running Light with Transistor Driver Output, designed for decorating in the car or any places. This kit uses 16 LED that arranged in a row and each LED turned On & Off in sequence and will create a single moving light in forward and reverse direction.
Input Voltage: 9-12VDC
Forward and Reverse Direction
Used 4514 IC
Reverse Polarity Protection
Flash Rate is adjustable
With Transistor Driver Output
Can drive the LED up to 100++ each output
Check off the components in the package against the component listing before assembly.
Start with the smallest components working up to the taller components, soldering any interconnection wires last.
Place and Solder the components into the board, make sure the components are in right position according to the overlay of PCB.
Test & Adjustment
After assembled, please check & ensure the value & polarity for all components were inserted into PCB correctly, wrong polarity connections of capacitors can cause explosion or failure.
Next, ensure all these leads are soldered, no solder bridges between adjacent pads and no dry joint.
Once confirmed, connect the power source to the circuit board.
LED light up one after another in forward and reverse direction until user turn the power off.
The running speed can be adjusted by preset (P1).
Package includes schematic, printed circuit board and components
Additional resistors (purchase separately) is required for Transistor Driver Output, let us know if you are facing a difficulty to figure out the value of resistor
You need to have a soldering skill and basic knowledge of testing
