Arduino - DIY GS-4 Seat

Hi @RacingMat

In a real car
accelerate_back is pushed into seat, belt shoulder straps go slack, brake_pressure on back reduces, belts go tight

In sim seat
accelerate_back paddles move forward push into back, which would cause the belt to tighten, hence let belt go slack to simulate real world.

brake_back paddles move back reducing pressure on back, belt would go slack, so tighten belt

Oh, I see what you mean...
Maybe @Schluzu could tell us if it's feeling like this actually in his Gseat?

mmmm You are correct for a real car except when running as a seat mover on accel the seat should pitch backwards sharp and short, giving you the feeling that you have actually thrust forwards, its about fooling the brain. And when you brake the chair pitchs forwards. This also rings true when using belts on a sim.
We do the same effects for Sway, because our simulators don't actually move side ways and forwards and backwards we need to emulate this with very slight and sharp movements in the opposite directions, which fools the brain into thinking we actually moved in a flat plane.
I would suggest trying both methods, we all are different and SimTools allows us to setup the way we like or feel is correct.

Hi @eaorobbie. I have a couple of the Turnigy S8166M servo's here now. Is there a Sketch available for the Nano that will allow me test the servo, possibly just sweep backwards and forwards or to sweep on each press of a key ?

Yea my model sketch will should work with the nano , as long as the signal wires are connected to output pins 3 and 4.
Ok if you can provide where you have connected the signal pins from servo I can show you which parts to change , or happy to do it for you.

You can connect the nano to the expansion card and signal wire from servo goes to D3 and D4.
The board with 5v/6v depending on servo, plugged in looks like the jumper can be set to either draw power from the socket or the Nano. I would first test with just the nano and expansion, but feel it will need an external power supply to cope with the number of servos.

Any details on expansion card, having troubles finding it, I normally build my own pcb for Ard to sit on. But details on theres and I can change the code to suit for you and others.

Hi. Thanks for that. I'll connect the servo's to D3 and D4 as suggested so that it shouldn't require any changes. Running the Model sketch as it is I assume that I will have to install and run the Simtools software and run a sim in order to get the servo's to move ? (or is there a way of testing the movement simply by running the sketch ?)
Thanks

@Roadster2 you can drive the Ard from the Ard IDE - Serial Monitor.
Set the baud rate at 9600
Commands to move is RxxxLxxx where R is the right servo and L is the left servo and xxx is 0 - 255.
