Arduino Motor Shield on a small robot
I recently picked up an Arduino Motor Shield R3 recently and found there wasn’t a whole lot of example code on the official Arduino website for it. After some tinkering around I decided to post some example code and a Arduino motor shield tutorial. I am going to break this down into sections: overview, setup, braking, direction, speed, and current sensing. Please keep in mind that this is for the Arduino Motor Shield R3 if you are using a different shield this information won’t be relevant.
Here is a Mesh Analysis Practice Problem to practice basic mesh analysis and circuit analysis skills. This is a fairly basic problems without super-meshes. These are the types of problems you could find in the beginning of a Circuit Analysis 1 type of class. Typically around chapter 2 or 3 of your textbook.
Mesh Analysis Practice Problem Number 1
There are several questions that could be asked for this problem.
Solve these questions using mesh analysis:
- What is the voltage across R2?

Menu System of Ti nSpire CX CAS
The Ti nSpire CX CAS has quite an extensive menu system. I though I would go through and list out the menu structure. I will eventually list how to use a lot of these features on the nSpire CX CAS calculator.
I had to purchase a scientific calculator for one of my classes so after some browsing online I decided to purchase the Ti-36x Pro and I was not disappointed. After using this calculator for a semester at college I decided post a Ti-36x Pro review. The Ti-36x Pro is packed with tons of features, such as the ability to solve simultaneous equations, evaluate definite integrals and a quadratic equation solver, just to name a few.
I use a metal Nite Ize Key Rack for my daily key carrying needs. After reading some of the amazon review of the keychain I saw several people had a few issues with keys becoming un-clipped and falling off. Although after about a month of use with the Key Rack, un-clipping has never happened to me. I figured it would rather be safe than sorry, so I decided to pick up a pair of the Nite Ize S-Biner Micro Locks.
