Hi Jason Morris,
We are a multidisciplinary engineers group that make three form of design, pcb, structural, and firmware design.
We normally use professionals software platforms like Altium for pcb design, Inventor or Solidworks for structural design, and Atmel Studio for Firmware design.
We have make many jobs related with led light design, temperature system control, distance measure indicator with ultrasonic system, servo controller system, inter alia.
What's more, we made many types of cnc machine design, and automatisations systems.
If you want to see some our work, we can send to you images or example design about that.
We have some experience about electronic design, if you have any question, contact us.
We propose that can use a minimal 8-bit atmel microcontroller(eight pin), specifically ATTiny.
In this wave design, the schematic and hardware design, will be more simple that other design(max eight componets).
Best Regards
IDSM Solution
