Help me decide on which programming language to learn

I just switched to Linux and I was wondering what programming languages should I learn to help me in my final year project. My project will be based on Formula Student E car. I need to do simulations and complex maths calculations, for which I can use MATLAB but to interface various sensors and developing a command module to control torque of the motor, I need something different. 

I've been doing some research on this but I cant decide which one to choose. Can Wendell, Logan or any other community members help me with this.

Thanks for your time.
