The suite adopts a 1.6mm double layer PCB, and the circuit consists of 57 pieces Blue LEDs. Under the control of MCU program, it displays an analogue hourglass image. You will need to research how to add the analogue MCU program yourself. It is not a straight forward task and you will need to learn how to upload programs to a microcontroller. There are videos on youtube that will help. The micro switch can adjust the speed of hourglass, the bright LED quantity at the same time is 28, and it can be used as decoration of small night light. 0.5W power consumption.

3. Principle explanation
The circuit consists of 57 3mm white hair blue LED composition of the hourglass pattern.In the control of the microcontroller, showing the effect of simulated hourglass.S1 is power switch, USB(Not include in the kit) and DC1(3mm power socket - Not included) are all power input interfaces, you can use any of them. ISP is the program download interface. The controller is SC15W201S with code (NOTE:Do not update the code inside arbitrarily, the internal code is not shared). If the user can write code, then the user can update the code by ISP interface. Switch S2 can control the speed of hourglass.
