This paper designs a smart hourglass control system,which use Arduino as the main processor.The sys-tem choses multiple 8×8 dot matrix display modules to display the movement trajectory of sand particles,and gravity sensing is achieved through rolling touch switches.The movement speed of sand particles is adjustable,and it also has the remote control function of an Android smart phone.The result show that the intelligent hourglass can simulate the traj-ectory and speed of sand particles through gravity sensing,and play an important role in electronic timing and display.Moreover,it can remotely set the time and display pattern from the mobile App.In addition,The system works stably which meets the requirements of smart small home appliance products,and has a certain practical value.
