Arduino Pin Turns On Transistor>>Transistor Turns On Relay>>Relay Connects Appliance To 120V Power Outlet. With that out of the way, you should also use a resistor to connect your Arduino to the transistor. This prevents the transistor from drawing excessive amounts of current and burning it ...

How to Set Up the DHT11 on an Arduino Wiring the DHT11 to the Arduino is really easy, but the connections are different depending on which type you have. Connecting a Three Pin DHT11: Connecting a Four Pin DHT11: R1: 10K Ohm pull up resistor ...
With these components, you’re all set to start building your robot! Maze Solving Robot Circuit Diagram As we are using the Arduino motor shield, the circuit diagram becomes simpler because no special connection is needed between the motor shield and the Arduino UNO. ...
Arduino ShiftIn() uses two signal pins (a digital output pin, and a digital input pin - i.e. almost any of the arduino pins) and generates a clock signal on the output, and receives data on the input, using the digitalRead() function. ...
The first parameter is the interrupt number. The Arduino Uno has two interrupts, interrupt 0 and interrupt 1. Interrupt 0 is connected to digital pin 2, and interrupt 1 is connected to digital pin 3. A0for interrupt 0, or a1for interrupt 1 as the function’s first parameter will indicate...
digitalWrite(pin_number,value) This function writes a digital value to a pin.pinspecifies which Arduino pin the digital value will be written to, andvalueis the digital value to which the pin is set.value must be either HIGH or LOW. ...
