First time playing with Arduino, Need Help With Coding

Other Hardware Robotics
1

I just just bought the arduino and iv been reading some books and throwing different things into the coding but im kinda stuck. I have no coding experience, only been reading and googleling to try to understand more so forgive me if i don't understand everything.

So i started building a remote controlled car using IR sensor as a remote. But i seem to be having some problems. It listens to the first input press of the remote but after that everything else is ignored. As soon as i restart it it would do the same again. Also It starts off with the wheels moving which i was hoping it wouldn't at least until i actually pressed a button on the remote. I have a remote that throws out steady numbers so i don't believe its a problem with that. Its most likely my lack of knowledge so if anyone can help me and see what i did wrong it would be greatly appreciated. Also feel free to throw guides at me or name of books i should read that could help.

Thank You!

There is a post at the start of each section called how to use this forum. Read it, especially the bit about posting your code using code tags. Then modify your first post accordingly.
