Led Driver

Introduction

    This module is laboratory unit for developing and testing ATTiny family firmwares used for control of led drivers through PWM.

     Led driver module based on two kp14653dp for cold and hot light mix. Expected input voltage is 220-240V. Two led plates also included into project. Every plate operated on ~75v so every smd led must be 6v. Previous version has only one kp14653 on board.

More information about KP14653DP https://en.sekorm.com/doc/2303875.html. Module also tested with KP14652 and working fine.

   Currenty PWM led dimming implemented with ATTiny85 as far as ATTiny13 has not timer and not enough amount of RAM. ATTiny45 and other has not tested yet. Firmware based on https://github.com/Arduino-IRremote/Arduino-IRremote TinyReceiver.h. NEC decoder are used.

   ATTiny85 has reserved 2 pins for uploading usb through firmare. New version of board has block of 4 pins connected to controller usb, vcc and gnd.

More details

At first runs Arduino Nano was used instead of ATTiny85 and It mostly complatible with TinyReceiver firmware. Better to use ATTiny with removable socket.
