Tutorial ESP32 CAM Rover

Good morning today in alfajor we will learn how to use the ESP32-CAM board and we will try to make this little robot explorer with camera this board has 16 pins to facilitate its handling we will use a pair of female female adapters now we must prepare the module to flash it using arduino in my case I will use an arduino nano these are the necessary connections we connect ground to IO-0. on the arduino we connect ground to reset. to put it in flashing mode. We connect 5 volts of the ESP to 5 volts of the arduino. ground to ground. rx-0 to U0R. tx-1 to U0T. now we must prepare the IDE of arduino go to file, preferences add the url that is in the description and give it ok now go to tools, boards and select "ESP32 Wrobert module". in partition Sheme select "Huge APP". and in programmer select "arduino ISP" now go to my github account I leave the link in the description and download the code open ".ino" here they must change "ssid" with the name of the network you want and the password you want as you can see we initialized the board in "soft access point" mode we will connect to the wifi network that will supply the board and not ours home wifi with this, we will not depend on the router and we can test it outside, accessing this address but if you want to turn it into a "web server" that is to say, the board connects to the router and then we connect to the router, you must change, this section of the code for this and change the "ssid" for the name of your home network and use your wifi password let's see the circuit I have used rechargeable batteries "18650" that I extracted from broken laptops. I will also use the wifi antenna of the same laptop which comes with the adapter necessary to connect it to the board. as you can see on the back of the board you will find the output of the antenna but it also has an antenna printed, you have to change this resistance and put it like this with this we will achieve a much greater scope We will use an integrated "l293d" to drive the motors I have used these motors but you can use other a servo motor "tower pro 9g" a "7805" for the 5 volts of the board the integrated and the servo in my case I have used bottle plastic which is very durable and strong to see more about of this topic you can see the following video. this is the assembly process. we connect the female female adapters. the power cables the output to motors and servo. the antenna. the camera protector. the servo that will move the camera from top to bottom the batteries and the engines. the supports of the front wheels, the wheels. the supports of the bands and bands. this is the result. now from a cell phone we go to wifi. we wait for the name to appear of the board network in this case "ESP32-CAM" it will ask us for the password and we connect in the browser we enter "192.168.4.1" and the next page by tapping on "start stream" we will see in real time the camera and we can already control our explorer robot I leave you with some images obtained well I hope it is useful to you.
