arduino -- IRmottagare med flera möjliga problem

Bakgrund

Hej! Nu till sommaren har jag bestämt mig för att lära mig om och kunna koda kring IRmottagning och sändning. Jag använder mig av ett program som heter arduino (och jag tror att den använder sig av c++ eller c, eller båda). Som start på mitt kodningsäventyr bestämde jag mig att följa en guide (https://learn.sparkfun.com/tutorials/ir-communication/all) som visar hur man kan ta emot och läsa IR-signaler från en TV-kontroll.

Möjliga fel

Dock har jag inte lyckats ta emot en signal från min TV-kontroll. Själv försöker jag aktivt felsöka det kommande problemen jag ska visa er som läser, men min erfarenhet med programmering är väldigt liten så jag kommer knappt någon vart tyvärr. Här ligger vad jag tror kan vara det möjliga felen, i ordning av jobbighet att reda ut;) :

1. elektroniken är sönder.här har en plastdel hamnat på snedden, men jag har ingen aning om det ska vara så eller om den fotfarende är funktionell, trotts lutningen.

2. jag har inte kopplat min "breadboard" på ett korrekt sätt. Förhoppningsvis är inte bilderna för röriga, men hursomhelst misstänker jag att jag kan ha kopplat upp något på fel sätt. Såhär ska det se ut enligt hemsidan -->

3. Jag har missuppfattat instruktionerna från hemsidans guide (och därav är koden fel).

Här är instruktionerna jag läste (bilden är suddig men länken jag gav förut leder en rakt till den mindre suddiga versionen)  

Det fanns dock ingen "IRrecvDemo", utan istället en "ReceiveDemo". Koden för denna var

#include <Arduino.h>
