USB light strip dimmer

 
Overview

Introduction

Used for dimming USB light strips without dimming function. Made using HK32F030MF4P6. The PWM dimming frequency is 3.2KHz, which meets the flicker-free requirement. The theoretical upper limit of the input voltage can reach 18V, so it is compatible with 12V and 5V light strips. Provide shell file.

Instructions

Just cut off the old push button switch and replace it with a dimmer. The middle button switches the light on and off, and the buttons on both sides increase and decrease the brightness. If you are not satisfied with the function, the code is in the attachment and you can change it yourself.
