Finished 2DOF 12V DC wiper arduino playseat

[kalarius]

I have the same problem with the motors.
The software of arduino is not the problem
The problem is the monster H bridge.
The one of the 2 chips is burned or does not work .
(i had connect the power with + to - so i burn the bridge)
When I burn the breadge I notice that the one motor speeds and react but the other on back way it is toooooooooo slow and I can stop it by hand and at the other way it is ok.
I use an other breadge and it is now ok.
see http://www.kalarakis.com/html/rali.html
Iam 123Kgr and the seat react fine

Thanks Kalarius for this information! I understand that.

@Monaco85 and kalarius: when your motomonster bridge burnt, was it cooled by a heatsinker and a fan?
Did you inserted fuse between motor and Hbridge or not?

[Monaco85]

Yes i have cooled the motomonster.
But no fuse. I will change the motors today.

I dont think that it is burned. Because it works only slower. I can maybe use popolu i have here. But i need to look what i have to change for.

[Monaco85]

Okay. I checked the wiper *
When i Change die wiper cables the other wiper moves much slower. But only down. It seams like it has not enaugh power to move faster.

I will Change to popolu in a few days.

When i Change die wiper cables the other wiper moves much slower.

-> hence it's the Bridge and not the motor!

what pololu bridge do you have ?
I have already some code of pololu755 http://www.pololu.com/catalog/product/755

[Monaco85]

i have this one

Cool! No need to change the code of this post:
it's the same as Motomonster
- 1 pin for speed (PWM)
- 2 pins for direction

yours

Can i stack the popolu on my arduino same as motomonster?

[Monaco85]

i changed to popolu and now it works.

/* VNH2SP30 pin definitions*/
int inApin[2] = {
2, 7}; // INA: Clockwise input
int inBpin[2] = {
4, 8}; // INB: Counter-clockwise input
int pwmpin[2] = {
9, 10}; // PWM input
int cspin[2] = {
0, 1}; // CS: Current sense ANALOG input
int enpin[2] = {
6, 12}; // EN: Status of switches output (Analog pin)
int statpin = 13; //not explained by Sparkfun
/* init position value*/
int DataValueL=512; //middle position 0-1024
int DataValueR=512; //middle position 0-1024


This is Setup. Thx to Tombo.

I have one more question.

Now it works with Race07. But the accell is very slow. How can i ajust the vipers to work faster.

I want to go back with my seat when i press the Gaspedal
