Este es mi avance: double aleatorio; int intentos; double numero_introducido; double math_random_int(int a,int b) { if (a > b) { int c = a; a = b; b = c; } return (double)random(a,b+1); } void setup() { randomSeed(analogRead(0)); Serial.begin(9600); aleatorio = math_random_int(1, 10); intentos = 4; Serial.println(String(“En que numero estoy pensando?”)); } void loop() {Read more

I am using a Arduino Uno with a Adafruit Ultimate GPS logger. The code is primarily the adafruit sample code, but I changed it for two reasons: To limit the amount of data recorded to what I needed. To include voltage data logged through the analog ports. It basically works, but the GPS data seemsRead more

My teacher just gave me a NFC tag v1.0 for a project. I have to use my phone to unlock a door. I searched on internet and I just found this code: #include “NfcTag.h” #include <Wire.h> NfcTag nfcTag; int led = 5; bool flag = false; bool preFlag = false; void setup(){ Serial.begin(9600); pinMode(led,OUTPUT); nfcTag.init();Read more
