5V Electronic Hourglass DIY Kit Funny Electric Production Kits Precise With LED Lamps Double Layer PCB Board 84*40mm

1.Introduction

The suite adopts 1.6mm double layer PCB, and the circuit consists of 57 pieces warm white LED. Under the control of MCU program, it displays analog hourglass image. 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.

2.Parameter

1>.Board Size：84*40mm

2>.Power Supply Voltage：5V

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(Do not include in kits) and DC1(3mm power socket) are all power input interface,you can use any of them.ISP is the program download interface.Controller is SC15W201S with code(NOTE:Do not update the code inside arbitrarily,the internal code is not shared).If user can write code,user can update code by ISP interface.Switch S2 can control the speed of hourglass.
