page 49/step 11 of the tutorial says "M2*4 screw in servo package". I can not find any M2*4, and the described items are not listed on page 2 of the tutorial either. Please help, where are they?
hello i have a question. I’ve bought this robot kit and the raspberry pi 4. Will I need to get the raspberry pi 4 up and running on its own on my desktop before connecting it to the robot? or do I just connect it to the robot without having set up the new raspberry pi 4 yet?
You need to setup the Raspberry Pi first. Please refer to chapters 0 and 1 of the tutorial. github.com/Freenove/Freenove_4WD_Smart_Car_Kit_for_Raspberry_Pi/archive/master.zip
The latest Raspberry Pi OS does not have the camera option. Please refer to our latest tutorial. If you need more help, please send an email to our support at support@freenove.com.
It is the camera module. You can download our tutorial with this link: github.com/Freenove/Freenove_4WD_Smart_Car_Kit_for_Raspberry_Pi/archive/master.zip

At 11:16, how did you guys tighten the screws into the blue board as the screwdriver that came with the package is too large, so how do you tighten the M1.4*5 screws?
hello, at 16:01 I attached the acrylic face part to the wrong side of the HC-SR04 Ultrasonic Module (blue) and camera (green), meaning that the acrylic part on the side of the car is on the left side instead of the right side. Is this a problem? Or can it stay like this? I'm unable to get the screws out of the HC-SR04 Ultrasonic Module, hence this question. Thank you!
Re TUTORIAL: Page 93 of the tutorial requests to issue the comand (w/o the quotes) "sudo chmod +x .config/autostart/start.desktop", however it returns an error 'CHMOD MISSING OPERAND'; what value do I have to add for chmod? Thanks in advance.
Hi! Please make sure you type the command correctly. If the issue remains, please send a screenshot to our support email at support@freenove.com. Many thanks.
Hi! Sorry but the Raspberry Pi is not included in the kit, you need to buy one yourself. If you have any concerns, please feel free to contact us at support@freenove.com.
hi, at 19:11 when i run the program (sudo python servo.py) i get this error : Now servos will rotate to 90°. If they have already been at 90°, nothing will be observed. Please keep the program running when installing the servos. After that, you can press ctrl-C to end the program.

@@Aritra-Paul i contacted customer service and figured out the issue, it was the female to female connection board between the pi bins and the car chasis bins for me and i just replaced it with female to female jumpers and now it works fine, but to be sure run the I2C test thing and see if the result is the same as in the tutorial pdf
@@bahaaldien6516I think I have the same issue because the connector between the pi and the car board doesn’t go in properly no matter how hard I try. Did you get a jumper yourself or use a provided one? I can’t push in the provided black connector which is showed in video 10:05. You are right I2C doesn’t show that it has connection. Any assistance would be helpful!! Thanks
Hello, I am having trouble pushing the connector to the Raspberry Pi 4B. The pin won't go in properly and come out the other side. I have pushed it very hard almost to the point the board sounds like it's going to break. at 10:05
Hi! I've tested every component as the video says and everything works except for the LEDs. The code works and doesn't give me errors, but still the LEDs don't light up. Pls any suggestions?
Hello Freenove, I have a problem with my it. When pressing the two switches the buzzer makes a continuous loud noise. I've tried nearly everything but I can't find the reason. The batteries are full and the cables are connected correctly. It does make a difference if and how the cables are connected. Sometimes the buzzer sound is very quite and sometimes it gets louder after like 10 seconds. Do you have an idea what might fix the problem? Thank you very much :)
so far all tests completed okay, no problems, EXCEPT: the camera test did not work: on the 'Raspberry Pi Configuration', 'Interfaces' panel I have no option turning any camera on, there are only these options: "SSH", "VNC", "SPI", "l2C", "Serial Port", "Serial Console", "1-Wire", "Remote GPIO". I enabled them all. The command "ls /dev/video0" did not list anything so I checked and could not find the "video0" directory. How can I enable the camera feature? Thanks for your help.
Sorry, "ls /dev/video0" is not available on the latest Raspberry Pi OS anymore. Please follow our latest tutorial to operate. github.com/Freenove/Freenove_4WD_Smart_Car_Kit_for_Raspberry_Pi/archive/master.zip
@@Freenove Camera issue resolved, thanks. Page 93 of the tutorial requests to add (w/o the quotes) "sudo chmod +x .config/autostart/start.desktop", which returns an error 'CHMOD MISSING OPERAND'; what should I add? Thanks in advance.
Very nice project, I just bought it and can't wait to have a chance to assemble it with my son. I have a couple of questions I would appreciate anyone to answer or share their opinion about: 1. Is there any reason to use Rpi 4 over Rpi 3, Rpi 3 B+ over Rpi 3 B, 3B over 3A, previous over Rpi2 or Rpi1 or Rpi0 (disregard the need for additional adapters and cables for rpi0)? 2. I guess everyone would like to try with the lower-power Rpi, are there any practical limitations (if everyone had/has an experience with this) if a weaker/older rpi is chosen? Any suggestion about the most balanced solution for Rpi model to be used with respect to both power consumption on one and features on the opposite side (maybe speed or potential for more sensors to be added)? 3. Is RaspberryPi OS Desktop a requirement, or Lite could serve the purpose as well? I guess it's easier to set up camera or wireless keyboard via Desktop OS, but other than that - does it have to be the OS with the Desktop? Thank you!

Hello, I'm wondering how to install the "connection board" with a Raspberry Pi Zero W (~ 10:00 in the video)? There are no pins like there are on the Pi in the video. Any help would be appreciated, thanks!
How do i connect the car to my laptop to start testing? And do i need to do all the things in the Chapter1 Software Installation Freenove 4WD Pi Car video?
Very useful video. I really interesting in this project but I have a question. What additional pieces my Raspberry Pi B+ would need to be used en this project?
I had the same issues find a good sized screwdriver (not to big not to small) you kind have to screw hard so it carves the holes to make them bigger when you do this the rocker will never come out again
The cable is connected to the ultrasonic module and the color does not matter. You only need to make sure the pins are connected accordingly, VCC of the module to 5V of the board, gnd-gnd, trig-trig, echo-echo.
