基于Arduino的LED开关老化测试系统

Aging Test System of LED Switch Based on ArduinoAbstract:This paper conducts in-depth analysis and research on the aging test of LED productsBy using the traditional LED aging test,low development cost,and suitable for application as aportrayal,the Arduino development board is used as the lower computer to design an LED switchaging test system.Used to improve LED test problems.The system controls the entire process of the system through the mobile phone Appconnected to the Bluetooth module of the lower computer.After the mobile phone App isconnected to the Bluetooth of the single-chip computer,the aging parameters set by the mobilephone App are sent to the single-chip computer to start the test.The single-chip computer outputsthe PWM signal to drive the LED driver chip to age the LED;The humidity value is comparedwith the preset value,driving the PTC heating module and humidification module,and returningthe data to the App at the same time;and the built-in 10-bit high-precision ADC reads the voltageacross the LED and transmits the voltage data to the mobile APP for overall control And finallyrealize the LED switch aging test.Keyword:LED Switch aging test,Arduino,Bluetooth
