Manufacturered by IS. Working voltage: DC 5V PCB board size: 84x40mm/3.31x1.57inch(L*W). When provide the 5V power supply the LED diodes will light up to simulate the sandglass movement (the top LED diode lights will drop down and the bottom LED diode lights will heap up) when reach the time press the button again it will repeat this process in the opposite direction with lots of fun. Warm tips: (1) Please check part values and quantities against part list always meter resistor values before soldering understand all part polarities and orientations. (2) Please make sure all components in right dirction and right place; and check whether any soldering points with poor contact this is very important in practicing and testing.
