Mixly Programming
- Step1：Since using serial monitor, we need to find "Serial Communication" from "Communication" item.
- Step2："Serial Communication" description.
- Step3：PIR sensor is an input device and the returned data is digital quantity, based on which we can find and drag out the digital input and output from "Input/Output".
- "Analog Input" description.
- Overall code description.
Debugging
- Step1：Select the right board card(Core USB 32U4) and COM port(Recognized automatically by default).
- Step2：Open the serial monitor.
- Step3：Check if the serial baud rate is the same with the pre-set one.
- Step4：Check the data: When there is human around it, the data is "1" and the status will keep about 4s.
