Reads a digital input on pin 2, prints the result to the Serial Monitor 从针脚 2 读取数字输入,并打印至串口监视器。 This example code is in the public domain. 此代码示例位于公共域中。 https://www.arduino.cc/en/Tutorial/BuiltInExam
Example code for talking to aTMP102I2C thermometer, like those available from Sparkfun, for example. Rather heavily based on some code I found in the forums, some samples, and a bit of personal investigation to make it all work. Based on my testing, the sensor overreads by around 5 degr...

Note the above code snippet. Press S1 LED1 turns on and stays on. Press S2 and LED1 turns off and stays off. (This could also be a motor control for example.) In each case pressing S1 or S2 returns a 1 or 0; the "if" command does the rest. Another note is the () must be...

This example shows how to fade an LED on pin 9 using the analogWrite() function. The analogWrite() function uses PWM, so if you want to change the pin you're using, be sure to use another PWM capable pin. On most Arduino, the PWM pins ...
