There are different ways of connecting a push-button to the Arduino board: You can connect to a power source and ground (GND), then specify if the push-button will be a pull-up or pull-down input. You can use a resistor to connect the push-button as either pull-up or pull-down. ...
When the pushbutton is open (unpressed) there is no connection between the two legs of the pushbutton, so the pin is connected to ground (through the pull-down resistor) and we read a LOW. When the button is closed (pressed), it makes a connection between its two legs, connecting the...
//or call config_gamepad(pins) again after connecting the controller. int error = 0; byte type = 0; byte vibrate = 0; void setup(){ pinMode(led,OUTPUT); Serial.begin(57600); delay(300); //added delay to give wireless ps2 module some time to startup, before configuring it //CHANGE...
Now that your setup has been completed, move into the main loop of your code. When your button is pressed, 5 volts will freely flow through yourcircuit, and when it is not pressed, the input pin will be connected to ground through the 10k ohm resistor. This is a digital input, meaning...
You can use the LDR to control the pitch of a sound by connecting a small speaker to the pin, as shown in Figure 1-9. Figure 1-9. Connections for a speaker with the LDR circuit You will need to increase the on/off rate on the pin to a frequency in the audio spectrum. This is...

Connect one end of the variable resistor to the GND (ground) of Arduino, and the other end to 5V (power). The middle pins of the variable resistor (usually the pins in the middle) are connected to an analog input pin from Arduino, such as A0.4. 编写代码4. Writing code打开Arduino ...
