Manufacturing method of LED colored light with mode control-EEWORLD

Collect

8 LED lights are directly connected to Vcc, no current limiting resistor is needed. This production uses a synchronous timer and uses sleep mode to save power.

If you want to change the pin that the LED is connected to, please modify the hardware.h file. If you want to change the brightness of the LED, please modify the Timings section definition in globals.h. This design has two external buttons, one for selecting the working mode and the other for turning the power on and off. When you press the mode button for more than 1.5 seconds, it enters the automatic mode and automatically demonstrates all the preset modes.

Note: The modification of the keyboard pins is also controlled by the hardware.h file.
