[Jonny999999]

original char adjustmen electronic broke down 3 time by now => replace it with custom control

ideas

• use free 4x mosfet outputs
• use joystick as control interface
• ~h-bridge?~
• relay board
• connector
  • additional connector (6 pins) required
  • upgrade existin 9pin subD? -> not practical due to wiring in armchair

tasks

• [x] update connection plan
  • [x] schematic
  • [x] connection to board
  • [x] wiring 3d-model box?
• [x] housing for relays on armchair
• [x] new connector
• [x] test relays (inverted?) -> pullup?
• [x] firmware
  • [x] implement adjust mode
