Gare-E: Arduino Sensor Tank Robot

One of the first projects that made programming feel real to me was a little tank robot I built at Indiana University.

I named it Gare-E.

It used an Arduino, a rotating ultrasonic sensor, servo motors, and LED feedback to understand what was around it. When it detected an obstacle, it had to stop, check another direction, and choose where to move next.

The LEDs showed what the robot was deciding, so I could see the logic working instead of only staring at code.

It was not a massive project, but it changed how I thought about building things.

Code was no longer just something happening on a screen. It could sense the physical world, make a decision, and produce a visible result.

A lot of what I build now is much larger and lives on the web, but the part I still enjoy most is the same: taking a messy real-world problem and turning it into a system that can respond to it.

This was Gare-E.
