Upload Code:
1) Connect the REV4 Board to a USB port on your computer.
2) Open the program in the code folder- Circuit 6 Button, or directly
copy and paste the code below on the Ardunio IDE.
3) Select UPLOAD to program the sketch on the UNO Board.
Now, let's begin the compiling. When the button is pressed, the LED
will be on. After the previous study, the coding should be easy for you.
In this program, we add a statement of judgment. Here, we use an if ()
statement.
Arduino IDE is based on C language, so statements of C language such
as while, switch, can certainly be used for Arduino program.
When we press the button, pin 7 will output high level. We can program
pin 11 to output high level and turn on the LED. When pin 7 outputs
low level, pin 11 also outputs low level and the LED remains off.
int ledpin=11;// initialize pin 11
int inpin=7;// initialize pin 7
int val;// define val
void setup()
{
pinMode(ledpin,OUTPUT);// set LED pin as
“
output
