Handheld high-powered hair dryer with speed controller and breathing status indicator light.

Overview

Please follow the CC-BY-NC-SA 3.0 open-source license. This project is for learning and research purposes only and is prohibited for commercial use.
Based on Xiaoyu's handheld high-powered hair dryer MAX push-button speed controller, this project modifies
and adds a breathing light function (breathing light in standby mode, switching to high brightness when the high-powered fan is activated).
The circuit uses a common flashlight constant current driver chip: AMC7135, which has a 350mA constant current capability and is powered by the BEC output of the brushless ESC.

The circuit board shown on the cover is for debugging purposes (given the current parameters of the LEDs purchased from Taobao, I only soldered one).

The LED board has also been redesigned, consisting of 36 0603 ice blue LEDs connected in parallel.

Please see the attached video for the actual effect.

12864 Serial cog LCD screen is not lit, black and unresponsive (excluding screen damage)
Has anyone used the 12864cog LCD screen with pin 10 of Lixian? Why doesn't it light up? It doesn't light up when powered on. The program is as follows #define CS LATBbits.LATB5 #define RS LATBbits.LAT
