TIP: Factor code for the compiler to process chains of Arduino if else code.For example the trivial code above could be re-written as: static int command=0; void d_action(void) { Serial.println("data"); command = 1; } void b_action(void) { Serial.println("begin"); command = 2;...
The code above calls function S1(). If the switch on DP2 is open it returns 0 or false - thus "else" is executed and LED1 is turned OFF. LED1 is only ON while S1 is pressed by returning a 1 when called. void loop() { delay(100); if ( S1() ) digitalWrite(LED1, 1); if...
Code in the body of theelsestatement runs. Below is an example showing how to use theif-elsestatement: intStudent1_Marks=92;intStudent2_Marks=20;voidsetup(){Serial.begin(9600);if(Student1_Marks>33){Serial.println("The student1 marks is greater than 33. He passed the exam."...
This example code is in the public domain. */ // Pin 13 has an LED connected on most Arduino boards. // give it a name: int led = 13; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); } ...

Do note that you cannot trust the color code of these cables, you must always check the wire against the plug pins. Especially considering the RX/TX pair of the pins may be flipped. Else if you have a 3D printer, you can use (Game Boy DMG-01 Link Port plug for dupont jumper wire ...

If code size or timer usage matters, look at these examples. The TinyReceiver example uses the TinyIRReceiver library which can only receive NEC, Extended NEC, ONKYO and FAST protocols, but does not require any timer. They use pin change interrupt for on the fly decoding, which is the ...
