I recently bought an Arduino and used JavaScript to toggle an LED through browser inputs—pretty exciting to see it work in real time.

On the flip side, I ended up frying two micro servo motors. In my first attempt, I accidentally increased the voltage too much. The second one stopped responding after I kept tweaking the power settings. Definitely a learning curve, but a valuable one.

Right now, I’m working on building a robotic arm. I’ve been experimenting with reducing friction on the joints and base, which helped improve movement. The University of the Fraser Valley has been a huge help by supporting the 3D printing of the parts.

I'm also thinking about making the setup more interactive—maybe adding voice commands with deep learning, hand gesture control with OpenCV, or even exploring EEG-based control using OpenBCI.

If anyone with hardware experience has suggestions or advice, I’d really appreciate it.
