Hello, I am doing an arduino project and I need a bit of help with a code. What I am doing is I am setting an Infrared led to pulsate at different frequencies and I use IR phototransistor to capture that light. Then the phototransistor sends the data back to the arduino and here I need to add...

The situation is part of a mechanism I have been working on. It is used for a bicycle to automatically store and release energy with a spring. It is somewhat similar to a car clutch. Homework Statement Two friction discs are rotating with different angular velocities and different torques. The...

We're implementing Dots and Boxes to logic circuits and the we would like to automate the process of changing turns. If you know the game, the game changes turn when one move doesn't score a point or form two or more boxes. I was able to create overlapping XOR gates that alternates from high to...

Hey everyone! This is my own personal project that I'm trying to get right but i ran into a bit of a problem. Here's the idea: I want to make a text based game where the player inputs data such as choices or numbers reflected what's asked of them from the program. The below program is...

Forgive me if this is in the wrong category or if there are any issues, this is my first post. My problem is that I need an idea for a brain project, as you may have noticed from the title. The class is a gifted enrichment course which, this year, is focused primarily on the brain. The gist of...
