So what i was thinking,
If i buy a second sim for my second phone and leave it on my desk.
i send custom commands to it on whatsapp, and it send things like the weather back and/or does some action, like on my computer start a game or takes a sceeenshot and send it back.

How would i go about this?
I want it for free, and program it myself so i have max customizability.

btw i got som free simcards

you could use a raspberry pi with a sim reader or an arduino, your choice. but i think it would be easier to make a small server on your pc and communicate over the internet with your phone.
If you want to use the rpi/arduino then you also need them to communicate with your PC so: phone->arduino/rpi->PC

You could use this on a server or a rPi so you wouldn't need any additional hardware, just a phone number: https://github.com/tgalal/yowsup

It's a python library for Whatsapp.

Whatsapp and third-party apps/bots don't get along very well. Unless you really need Whatsapp, I'd look into other applications like Facebook Messenger, Telegram, Slack etc.
