Alright folks, let me tell you about this "smart scrubber" project I tackled recently. It was a fun one, and I learned a ton, so I figured I'd share the whole shebang with you. Get ready, it's a bit of a rollercoaster!

It all started with me being plain tired of scrubbing. Seriously, who enjoys that? So, I thought, "Why not build something to do it for me?" And that's where the idea for the smart scrubber was born.

The Initial Brainstorm

First things first, I sat down and scribbled out some ideas. I needed to figure out the basics:

• What kind of surfaces would it clean? (Tiles, grout, sinks... you name it!)
• How would it move? (Wheels? Tracks? Suction cups?)
• What kind of cleaning power would it have? (Rotating brush? Spray nozzle?)
• How would I control it? (Remote control? App? Voice commands?)

I even did some gasp drawings. They were terrible, but hey, they got the point across.

Gathering the Parts

Next up was the fun part: raiding my spare parts bin! I'm a bit of a hoarder when it comes to electronics and gadgets, so I had a decent stash to work with. I ended up using:

• A small DC motor (for the rotating brush).
• Some plastic wheels (to get it moving).
• An Arduino Uno (to control everything).
• A Bluetooth module (for remote control via my phone).
• A small water pump (for spraying cleaning solution).
• Various wires, resistors, and other electronic bits and bobs.

Of course, I had to order some stuff online too. Amazon became my best friend for a week.

The Build Begins (and the Problems...)

Alright, time to get my hands dirty! I started by building the chassis. This was basically a small platform made out of some scrap wood I had lying around. I attached the wheels and the DC motor to the chassis.

Then came the tricky part: wiring everything up. Let me tell you, it was a mess of wires at first! I spent hours soldering, connecting, and testing. I even managed to fry a resistor or two (oops!).

Coding is My Kryptonite

Now, I'm not a programmer by trade, so the coding part was... challenging. I used the Arduino IDE to write the code. The basics were simple enough: control the motor speed, activate the water pump, and communicate with the Bluetooth module. But getting it all to work together smoothly? That took some serious tinkering.

I spent a lot of time staring at the screen, scratching my head, and muttering to myself. But eventually, I got it working! I could control the scrubber from my phone using a simple app I found online.

Testing and Tweaking

Time for the moment of truth: testing! I put the scrubber on my bathroom tiles and turned it on. And... it sputtered, spun in circles, and sprayed water everywhere. Not exactly the smooth, efficient cleaning I was hoping for.

Back to the drawing board! I realized the wheels were slipping, the motor was too weak, and the water pump was spraying too much. So, I made some adjustments:

• I added some rubber bands to the wheels for better traction.
• I upgraded to a more powerful DC motor.
• I added a valve to control the water flow.

Success (Sort Of)!

After more tweaking, the scrubber was finally working! It moved in a (mostly) straight line, the brush rotated nicely, and the water sprayed evenly. It wasn't perfect, but it was definitely scrubbing!

The Final Result

So, what did I end up with? A slightly clunky, but functional, smart scrubber. It's not going to win any design awards, but it does the job. It saves me time and effort, and that's all that matters.

What I Learned

This project was a blast, and I learned a ton. Here are a few takeaways:

• Planning is key. Spend time thinking through the design and functionality before you start building.
• Don't be afraid to experiment. Try different things, and don't get discouraged if things don't work out the first time.
• Coding is hard, but rewarding. Even if you're not a programmer, you can learn enough to get by.
• Always wear safety glasses!

I hope this inspires you to build your own smart scrubber (or whatever crazy project you've been dreaming up). Just remember to have fun and learn along the way!
