Controlling it via an ESP8266

A project log for Hacking a Flippity Fish™️

Every time we turn on this new cat toy, our cat gets scared. Maybe it wiggles too much. So I hacked it.

I simply desoldered and lifted the two microcontroller pins, and connected the H-bridge driver to an ESP8266 dev board I had lying around.

I wrote a small sketch based on Blynk (GitHub repo in project page) and here's the result:

The next step is to use a smaller ESP-01 module to fit inside the inner plastic body. I couldn't do that before because I was missing an USB-to-TTL converter needed to program it.
