Gynecology chair - Microcontroller program needed

-Program microcontroler ATMEGA8-16PU

-3 Actuators

-3 HALL sensors input (position of actuators)

Signal is DIGITAL on sensors

- each actuator has end switch on up/low limit

- Soft start on Actuators

- 6 button hand control

3 actuators up/down

Hand control separate from foot control

- 6 button foot control

3 actuators up/down

3 taster preset programmable position

I want to be able to use foot control to be able to adjust position

of actuators, but also i need 3 of the tasters to be double function

when i set up chair in certain position i need to be able to save position on one of the tasters

and later recall it

i need this for 3 out of the 6 tasters

-on power on if needed go to 0 an all 3 motors to establish 0

Chair design is so that when the 1 of the 3 actuators is working, other 2 need to follow it in order not to put a patient in a bad position.

I can provide 3D vector file, where relation in positioning can clearly be seen

I NEED THE PROGRAM TO COMPENSATE FOR THIS if you can not adjust for that, please do not bid

I will consider project to be completed when:

Program file for the micricontroller delivered

and hex

Make sure compensation in position movement of the actuators has been implemented correctly

I will test for this before completing the project

PCB-s are finished, so testing should be fast

(video chat is available for additional corrections)

I will need explanations, and possible help implementing the project

IF YOU CAN'T help skip this one ;)

Please when applying write how long would it take to deliver the project.

If you can not communicate, please skip this project, I had another Freelancer take the project, deliver wrong files, wrong PCB-designs... cost me money, time, and additional resources, and avoided communication with excuse that they were busy.

Attached are microcontroler PCB-files.

One more time HALL sensors are Digital
