Tutorial From AtoZ : 2DOF arduino wiper playseat

Im using your firmware with ard.. but its freeking my computer how can i isolate it? Need Galvanic isolator? How can i implement theres some diagram for me to follow? My friend has the board etc.. and his computer runs normaly withougt isolation thats strange

What is the problem exactly @trust928?
What are the symptoms on your computer?

Hey pipis20015
Man im my setup is the ard+ small pcb to join the singal and the hbrigdes... when i move the slider in game engine, my screen flikers it keeps turning off and on when i tried to play a game when the simulator starts to move everything frozes... im sure its because of the commom ground, an friend has the same setup and board s but he doesnt had any problem i dont know why

You have to check your motors.
Are they ground isolated?

Yeas they are isolated i have opened them and cuted the wire that goes to the case, so i think its not it and more sugestion?

Are the computer and the simulator power supply plugged in the same wall outlet?

Try to use a different wall outlet for your computer and the simulator power supply.

Yeas they are, whats going on with it in the same wall oulet?
Anyway i fixed the issue by puting opto isolators..
The firmware is very good..
Just a bit jerk but i just need to config i think that the bits should tranfers more quick.. i feel a delay some times but maybe just configuration thanks to all

1/ can you tell us more on the isolators you're using?
2/ good!
3/ jerk: just check if it is a mechanical gap?
delay: are you at arduino top speed in windows and Simtools? you can lower Tolerance parameter

Sometimes when the motors draw exesive amounts of current from the power supply ... I noticed some spikes on the voltage of the wall outlet (confirmed by my ups tripping on and off because it also detects the voltage difference).

Hello, I would like to ask about the arduino code:
#define RV 2 //beware it's depending on your hardware wiring
#define FW 1 //beware it's depending on your hardware wiring

What does it mean? Is it the connection between motor and the motorshield or is it something else?
Thank you

Wow impressive, that awesome move.
Good work, thanks for creating this DIY topic, that help me a lot.

yes, it is

Hello RacingMat, I would like to ask about your arduino code. Did you use any PID Controller or other Controller in your code? Because I didn't find any controller that controls the feedback of the potentiometer. If there is, could you pointed out which part is it? Thanks in advance.

it's written in the code...

Code:

    // PID : calculates speed according to distance
    pwm=195;
    if (gap>50)   pwm=215;
    if (gap>75)   pwm=235;  
    if (gap>100)  pwm=255;

there is only a P (Proportionnal) controller: the speed depends on the gap between real position and order.

Okay, I get it now. So if I may know what kind of control system did you use? Is it linear control system or on and off control system or something else? Thanks...

It's not on/off as it's Proportionnal.

Really nice build and a huge inspiration to my build 'to come' how are the motors holding up? fast enough to feel the fine details of movement?

yes Smolka are perfect to feel details! but they are no longer available...

glad my tutorial is useful

Thanks! Maybe i found a cheap replacement for the Smolka (NIDEC 404.458) motors. I have them in order right now and i expect them to arrive this week. Then off for a SIM build

Eager to see your project!
