Connect one terminal of your speaker to digital pin 9 through a 100 ohm resistor, and its other terminal to ground. Power your photoresistor with 5V, and connect it to analog 0 with the addition of a 4.7K resistor to ground. 将扬声器的一只脚通过 100 欧姆电阻连接到数字针脚 9,另一只脚接...
Connect one of the button pins to pin 11 through a ~ 5 kOhm resistor, and the other pin to ground (GND). Press the button. You can now use ‘digitalWrite’ or other other functions to switch on an LED, relay, adjust PWM duty cycle (for example, increase the brightness of a lamp)...
