The SG90 Data Sheet shows that the work frequency is 50 Hz. So the frequency of PWM should be set to 50Hz.
import PCA9685 as servo
pwm = servo.PWM()
pwm.frequency = 50
pwm.write(0, 0, 509) # Left 90 degree
pwm.write(0, 0, 300) # 0 degree(middle)
pwm.write(0, 0, 109) # Right 90 degree

Hello, is there a way to make the kit compatible with Rpi 1 model B ? Do you know of somebody who could have produced an adapter or if there is something i can 3D print ?
Thanks!

Hi,
video_dir.setup(busnum=None) does not work.
There is already a function to set the raspberry pi revision in PCA9685.py, and specifying a busnum in video_dir prevent controlling the camera.
Do you accept pull requests?
I'm willing to contribute if needed.

I've not found any mention of which properties of 18650 batteries are recommended (high drain? 8 or 15amp?, capacity?)

Hi my name is mostafa!
at the very end of instruction, I run the server program first, the the client program and I can see the graphical user interface of smart car, but when I hit home, left, right or other key, I got the error on the server terminal on raspberry pi that says:"cannot recognize the command:home" or "cannot recognize the command forward"...
I will appreciate if you help me on this

Hello :-)

I want to try to use Japanese Raspberry Pi 3 module.
However, I can't run i2cHelper.py well because the revision number of Japanese Raspberry Pi 3 is "a32082" .

Can I modify i2cHelper.py as follows?

RPI_REVISION_3 = ["a02082", "a22082"] → RPI_REVISION_3 = ["a02082", "a22082", "a32082"]

Best regards.

Hi

This is occurring on a Raspberry PI ZERO. Other versions I've used 2 and 3 are working fine.

Not sure, if it is an issue, which needs to be reported here, but the Android app does not work at all.

The python client app script works fine.

Where is the web client? i failed to install pyqt5 so i would like to use the web client but can't find it.

I purchased your car kit, assemble it properly and I am using raspberry pi 3 ,I first calibrated the car but it is not going straight it always take slight curve! Please suggest

When I start up the app on my phone, it connects to the video car just fine. I can move it forwards and reverse, pan the camera every way possible. But when I tilt my phone, the video car does not turn. Do you think it is because I have a raspberry pi 2 model b+ and not a raspberry pi 3 model b+? Or could it be the fact that the app was created for an older version of android? Or is my Samsung Galaxy Amp 2 just not compatible?

Hello,
I'm aware this is not really a new issue, but I did read the other posts involving this issue and those advices didn't work for me. This is what I've accomplished so far:

• connected and reconnected wires, including the famed GND wire between Rasp Pi and servo control. I used the wires that came with the Car Kit.

• When I run sudo raspi-config I get the option Advanced (#7) but there is no i2C in the menu.

• I also tried sudo python i2chelper.py, but it gives me an Error Message.

What am I doing wrong? Should I recheck the wires? Should I solder them to GND? Should I get new wires?

Please help,

Emil

Any solution? :/

How to use the UART port on Robot HATS to communicate with Arduino?

I am trying to run some code on raspberry pi 4 model B but it keeps giving me error The error is: (Error. Pi revision didn’t recognize, module number: c03112).
Any help will be appreciated.

I'm having a strange experience with the camera mount. Even if I calibrate it correctly, once the server starts, the camera literally falls down. I need to calibrate it to point to the sky so that it points forward, once the server starts.

But this is not the main issue I have. The entire construction is constantly vibrating and it is absolutely not robust enough. I had a little accident and all the screws fixing the holder of the bottom servo have been pulled out.

But what is this with the vibrations? If I pan a little left or right, the vibration stops. This is pretty strange, as if the servo would constantly getting contradictory orders

I had build the car and as instructed install and configure all the software and parameter. I had started server and client which is successfully connected for calibration test when i click on run the car does not move.

Can you please help me that.

thanks

Amir

When I run sudo python cali_server.py the bottom servo will move all the way one direction and then stop. That servo will then become unmovable until I power down the entire car by pulling the batteries out. I have looked for a process but I'm not sure what it would be.

Here is the output as it shows on the screen when I run the python script:
pi@raspberrypi:~/car_dir/server $ sudo python cali_server.py
offset_x = 11
offset_y = 0
offset = 0
turning0 = True
turning1 = True
Waiting for connection...

I've tried to ctrl-c out of the python script but that also does not change anything.

Hello !
I have a problem running the calibration.
When I start cali_server.py my Cervo is making 'noise' and eventually get warm.
I guess this is not some normal behaving...
I've unplugged and plugged everything about 3 times (or more)...
Where did i fail? Any clue?

Hey, what do you think about using a git submodule for mjpg-streamer? I ask because the source code for mjpg-streamer in this project is 2+ years old; using a module removes the source from your repo, and makes it very easy to update to the later commits.

A quick overview of the change: the mjpg-streamer directory at your root directory would be replaced using a module to https://github.com/jacksonliam/mjpg-streamer. Docs would need changed a bit to say git clone --recursive and require the cmake package.

If you're okay with it, I can make the change and submit a PR. Thanks! 😸

Hello good, is it possible to migrate the code that can be used today? following the installation guide there are several commands that do not work.

I wanted to use the car and the memory was damaged and now I try to reinstall and it is impossible....

Hi,

I have the BMP280 sensor from robotdyn.

this is how i have set it up:

i have connected :
sensor : breadboard(t-split)
5v : 5v
gnd : gnd
sck : pin3
sdi : pin2

this is the error that i get, after i run the 31_bmp.py file from the sunfounder lessons.

there also is an 31_barometer.py file. I also tried to run that but then the error is: no module named adafruit_bmp. i have pip3 installed it, but this error still pops up.

Anyone who could help me with this. Would very much appreciate it. (excuse my bad English)

When I put in line 2 it says it doesn't exist, I don't see a http_server directory

pi@raspberrypi:~/Sunfounder_Smart_Video_Car_Kit_for_RaspberryPi/server $

Greetings everyone,
I am following the pdf of starting with Sunfounder Raspberry Pi Video Car kit, but unfortunately I am having a problem with the motors. I did calibrate them successfully. I even made sure that they are turning in the same way; but when I runt the code for controlling the car using pygame which i am sure it works, the motors are turning in opposite direction. Can anyone please help me. Thank you in advance

The android app is not available in the play store. The link in the readme of the html_server is broken. Please provide a valid link to download the android app

Do you have some user forum? Or I should post my questions here??
