Working principle:

      HQS1416 is a kind of highly entertaining human body response test module circuit. It tests human body response speed according to the time of human pressing the button after they see the random lighted indicator lights and shows the test result by two digital tubes. Connecting to the power, HQS1416 begins to test itself, and the digital tube displays "88". With buzzer tweeting once, finally the digital tube displays "--", which indicates that the system can begin to have a test. When the people to be tested presses the "start" button, HQS1416 randomly delays a while and D1, D2 will be on. HQS1416 will calculate the score by the time for pressing the button of the person, score from 0 to 99. 0 point for those who press the "RIGHT" button when D1 (left) is on, press the "LEFT" button while D2 is on, and do not press any button in more than 5s. After a test, the "LEFT", "RIGHT" button will be locked, D1 and D2 will keep on, and the digital tubes displays the result. This state will not change untill someone presses the "START" button to have another test. If the digital tube displays “99” or "0" indicates you pressed the wrong button, 85~98 means sensitive response, 60~85 means average level, and less than 60 means slow response. FMQ1-W is buzzer, Q3 is the driving transistor of the buzzer, Q1 is single digital tube drive, Q2 is tens digital tube drive, R1, R2, R3, R4, R5 are current-limiting resistances, C1 is filter capacitor , AN1 is the "START" button, AN2 is the "RIGHT" button, and AN3 is the "RIGHT" button.
