I just want to know if you think you can update Zeus car by adding new features that’s exist physically. I notice there’s a flash light on ESP32-cam, I saw some forums to turn it ON in EZblock but is it possible to turn it ON with sunfounder controller? I found that camera image is dark even when the room’s lamps are all ON. And another question, if I want to customize sunfounder controller, where do I go to assign buttons\switch?
You can add the ability to control the led in the UNO code by simply calling the Aicamera function:
aiCam.lamp_on(5); // brightness level, 0~10
aiCam.lamp_off(); // brightness level, 0~10.
You can add the on/off control to the app (assuming it’s control number M) and then modify the onReceive() function in Zeus_Car.ino to add the control code:
if (aiCam.getSwitch(REGION_M) == true) {
Serial.println(“lamp on”);
aiCam.lamp_on(5); //turn on cam lamp, level 0 ~ 10
} else if (aiCam.getSwitch(REGION_M) == false) {
Serial.println(“lamp off”);
aiCam.lamp_off(); // turn off cam lamp
}
in which section should i add thoses commands?
for : aiCam.lamp_on(5); // brightness level, 0~10
aiCam.lamp_off(); // brightness level, 0~10
should i add it to ai_camera.cpp or .h and which lines, at the beginning, middle, end? Do i enter it straight like that?
I’m getting this error after checkout the code :

There’s photos of where I add codes
I’m sorry, I’m so newbie, even with ChatGPT, I’m turning in round. I really need a good book about coding, from newbie to pro… 
What do you think about those instructions: Zeus Smart Car Kit: light and WiFi signal boost to explore the dark – Renzo Mischianti
Sorry, the lamp_on() function is not included in the aiCam class of Zeus Car, the correct code is located in another branch and that branch has separated ai_camera.h, ai_camera.cpp into a separate library. Anyway here is the correct way to do it:
- make sure the camera’s firmware version >= 1.3.0, the ESP32 firmware version will be printed when the code is run.
- refer to SunFounder_AI_Camera/src/SunFounder_AI_Camera.h at main · sunfounder/SunFounder_AI_Camera · GitHub .
and
SunFounder_AI_Camera/src/SunFounder_AI_Camera.cpp at main · sunfounder/SunFounder_AI_Camera · GitHub
Add lamp_on and lamp_off function definitions to ai_camera.h, ai_camera.cpp. - add in Zeus_Car.ino onRecive() function:
if (aiCam.getSwitch(REGION_C) == true) {
Serial.println(“lamp on”);
aiCam.lamp_on(5); //turn on cam lamp, level 0 ~ 10
} else if (aiCam.getSwitch(REGION_C) == false) {
Serial.println(“lamp off”);
aiCam.lamp_off(); // turn off cam lamp
}
Ok, thanks you for the photos, it’ll be easier for me to enter codes at the right place.
Another question, is it possible to change the switch for a rheostat(slider) to control the brightness from the app?
I’ve try what you told me and i got this error :

What am I doing wrong?
At least, can you made changes into the original codes, test it on a Zeus car, confirm that’s work and send me the files?
I have added CAM lamp control to the code. You can re-download the modified code from github GitHub - sunfounder/zeus-car: SunFounder FPV Omni Car for Arduino

It works, thanks you SOOOOOO MUCH. I think alot of persons will like this feature.
