The tutorial provides code in two ways:Arduino blink multiple LEDs Arduino blink multiple LEDs using arrays.We will use three LEDs as examples. You can easily modify it to adapt for two LEDs, four LEDs, or even
In this tutorial, we learn how to control LED with using Arduino, how to program for Arduino to turn LED on/off, and how to blink LEDHardware Required 1 × Official Arduino Uno 1 × Alternatively, DIYables ATMEGA328P Development Board 1 × USB 2.0 cable type A/B (for USB-A PC)...
int p2){ val = p1+p2; return val; } void printVal(){ Serial.println(val); } void setup() { // put your setup code here, to run once: Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: add_vars()...
