@Lee fully charged the battery should last 8 minutes. Let me know if you have any other questions.

@smilebean you can make the CoDrone follow a colored object if you know how to use OpenCV. We have been able to follow colored objects but not humans that requires human recognition. Currently we are working on creating these tutorials for OpenCV and once we have them ready I will notify you.

Hello @rcron2 the code

#include <CoDrone.h>

void setup() {
   CoDrone.begin(115200);
   CoDrone.pair();

   CoDrone.takeoff(); //goes up and hovers for 3 seconds
   CoDrone.hover(2); //hovers for 2 seconds
   CoDrone.land(); //lands the CoDrone 
}

void loop(){    
   byte bt8 = digitalRead(18);    
   byte bt4 = digitalRead(14);    
   byte bt1 = digitalRead(11);

   if(bt1 && bt4 && !bt8){    
   CoDrone.emergencyStop();
   }
}

has a killswitch inside the loop, since the setup code is doing one line after another it will take time to get to the inside of the loop. The killswitch is there for once the program is over if the CoDrone is still flying you can make it land. You can also double-click the BLE modules black button to kill the drone mid-program. Let me know if you have any other questions.

hello, @eboswort so the four pins are for the power connection and for debugging the CoDrone. If you access those pins using external sensors it is at your own risk. If accidentally connect the pins incorrectly you will be out of the warranty. The payload capability for CoDrone is roughly 7 grams so if the sensor is lighter than that you can place it there, however battery life will drop with the increased weight and power draw. One thing to note is the firmware on the CoDrone itself is not accessible to the public so you would need some other form of communication to send the temp data. Let me know if you have any other questions.

@smilebean You should not be getting a delay of 2000ms. I know however if you send a bunch of commands one after another the CoDrone will keep a buffer of all the commands therefore doing things you told it before. When using the keys you should not hold them down but instead tap them.

@smilebean said in How to control my Drone with OpenCV?:

You may need to change the size at which you are saving the video at. First find out what the size of the output video is.

@smilebean So 4000ms and 3000ms delay is not normal, what code are you running? Do you have the BLE module driver installed on your computer? the SiLabs Driver? Also can you post the code you are trying to run here? Thank you!

hello @efraim-fleisher it appears you placed the #include <SmartInventor.h> inside of the setup function. It must be placed outside of the setup on the top. Hope this helps.

Hello @Sarah-renfro I am sorry to hear the CoDrone is not behaving correctly, are you available for a video call this week?

@smilebean I can explain everything over the video call. I will be on the website https://appear.in/robolink-support let me know if the site works for you. It is best if you use a google chrome browser.
