- Handshake tester–Moisture Sensor
I found out that if I hold my hand onto the sensor, it could detect my hand’s humidity. Therefore, I created a handshake tester– To determine whether your hand is too sweaty for handshakes. Anyone who wants to make friends can use this gadget.
(1) If your hand is not sweaty (sensorValue<=200), it would tell you “You are good to go~ Go and make a friend!”.
(2) If your hand is too sweaty(sensorValue<200), it would tell you “Your hand is too wet! Rub it! /n Press the reset button if you think you are ready!”.
2. A doorbell that detects “knock”–Vibration sensor
This doorbell can detect whether someone is knocking on the door and gives out a doorbell ring, blinks the LED, and displays “knock!” *n onto one’s screen. This can help those people whose ears are a bit of insensitive to know whether someone is knocking. The 3 ways of reminding (light, words, and sound) help to make sure one notices it even if they are too observed in work.
The screen displays “knock!”*n when the vibration detects a “knock”.
The buzzer plays out a toneMelody and the LED blinks.
3. Coding is like implementing the idea into a language that the computer could understand. The idea shall follow a logical way. A scheme is similar to a program. There is this order of logic that requires coder’s clear knowledge of his idea.
4. The computer is penetrating into every corner of our life. Everyone could be replaced by the computer someday, as the artificial intelligence is growing, developing, and evolving at an incredible speed. Nowadays, computers become a daily object, a tool to all informative questions, a helper of many kinds of work.
