The Cat Laser Toy - V2.2.

The latest attempt and making my cat(s) happy.

Project In Progress.

• Pardon while the kinks and bugs are slowly squashed.

Usage:

• The push button/switch will turn on the laser and start the auto run mode.
  • Auto mode still needs some help. it 'works' for now though!
• To use the joystick, press down on the joystick and the D13 led will light up to show that manual mode is active.
• Joy stick can then move the servo arm around. <-- This is still a bit off. I may need a better quality joystick for this.

To Do:

• Fix the servo angle values.
  • 0 degrees on bottom servo should be pointing left
  • 180 pointing right
  • 90 straight ahead.
  • (this all could be fixed by adjusting the servo arms alignment.. im being lazy though)...
• Get the timers to work.
  • Servos are moving too fast. (or too slow or even not at all...)
• Get auto mode to work... <-- this more or less works right now..
• USE DUAL CORES!

Plans:

• Add dual core usage for the ESP32's two cores.
• Incorporate the Blynk library to use remote control via wifi.
• Web UI?
• Add bluetooth/ble
• Add more buttons or switches to change to different running modes.
• Make a second one for my other cat!
• uh...

  • Bottom servo (Horizontal movement) connected to pin 33
  • Top servo (Vertical movement) connected to pin 27
  • You could use your own 2 servo set up as well.
• Bread board.
  • Use a longer breadboard to mount the mini pan tilt kit to the breadboard with header pins or any other method.
• Wires...
  • I prefer wires cut to the proper length to avoid the servos catching them and pulling them out of place. (It also looks better)

Total cost for parts is about $55-$65 or so depending on what you already have or need.
