arduino projects input output control using button. const int button_a =2; //define button 1 // const int button_b =3; //define button 2 // const int led_A= 12;//define led 1// const int led_B =13;//define led 2// int button_State =0; int button_State1=0; void setup() { pinMode(button_a,INPUT); pinMode(button_b,INPUT); pinMode(led_A,OUTPUT); pinMode(led_B,OUTPUT); } void loop() { button_State=digitalRead(button_a); if(button_State==HIGH) { digitalWrite (led_A,LOW); } else{ digitalWrite( led_A,HIGH); ...
