- P1:Here’s a version that failed, feels like a connection problem（true）
- P2:Figured it out: the button press signal goes into the 3 interface（helped by Connor）
- P3:I’ve done it in reality as well (there was a glitch in the process, I neglected to connect the negative to GND)
int led1 = 8;
int led2 = 5;
int button = 3;
int pressCount = 0; // googled
void setup() {
pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(button, INPUT);
// led off
digitalWrite(led1, LOW);
digitalWrite(led2, LOW);
}
void loop() {
// read the button
int buttonState = digitalRead(button);
if (buttonState == HIGH) {
\ delay(200); // don’t know if delay is necessary
\ pressCount = pressCount + 1;
\ // googled how to read press twice
