ESP32 #1 Getting started with Arduino core

hello all this video is on getting started with the ESP 32 development kit we're using Arduino IDE the ESP 32 modulus 2 processes with built-in Wi-Fi and Bluetooth ble it has got more number of ADC pins as compared to node MCU and other peripherals like DAC UART SP a high to C and built-in sensors like touch temperature and Hall effect the C p210 2ic provides the USB functionality for the SP 32 development board it has got to reset buttons two buttons one at the top is en and the at the bottom you have the boot button to upload code you can very well place the ESP 32 module on breadboard but to access the GPIO pins on both sides you need to breadboards tear open the ends of breadboard like this and then fix both of red boots together there is lock you can see just press lock the top red boots now you can place the ESP 32 development board on the center and you have access for GPIO pins on both the sides now let us see how to implement our Dino core onto ESB 32 using boards manager open the latest Audino ID go to file preferences at the bottom of the next page your do paste the Jason link for boards manager already know core boards manager the link is given in the description below or you can visit Express if I have get up page and the scroll down to locate the instructions for implementing or Dino core at the bottom of the page you can find the jason link for boards manager copy this Jason link and then paste it under file preferences you can use control-v to paste the link here if you have already installed node MCU you will see another Jason link here now you put a comma and then paste the new link now on the tools boards open boats manager and then search for ESP 32 you need a good internet connection for installing this boards Audino core boards manager using boards manager select the ESP 32 for s press AF and select the latest version and click on install it will take a moment to install the Audino core for ESP 32 once the installation is complete you can close the arduino ide and then open it again let us now blink the inbuilt LED on ESP 32 module the ESP 32 module has got a blue inbuilt LED on board the inbuilt LED is mapped to GPU to pin the GPU to pin is 4th pin from the bottom it is mapped to the inbuilt end in a LED we can also use an external ID led to see the result the long lead of the external LED is connected to GPO to and the short lead is connected to ground through a 330 ohms resistor we can use male to male jumper wire to achieve this now connect the USB cable to ESP 30 to open the device manager and node on the compote allotted you should have installed the CBT 1:02 driver previously to see the comport allotment not on the compote allotted here inside the device manager and in Audino ide under tools select the board as ESB 32 div.module now under tools you can see other settings you leave it to her default upload speed CPU frequency flash frequency only be to default and select the port as the one seen under the device manager now from file examples open the blink sketch inside the blink sketch the LED built-in is switched on for a moment and then after a delay it is switched off now we have to define the LED built-in as LED built-in is map to GPO two we use this statement at the top define LED built-in two instead of GPO two we use only the number two this is how to use access the GPIO pins now save the save the code and then click on upload at the bottom of the IDE you can see the compelling message once the compiling is over you can see dots and then continuous line as soon as you see the continuous line you press the boot button to upload the code now it shows done uploading this is how to upload the code on to SB 32 you have to press the SP 32 boot button and the code is uploaded now you can see the result the blue built in LED blinks and then the external LED also blinks now let us change the LED to GPU 15 the GPU of 15 is the third print from bottom let us shift the LED to GPU 15 connect the long lead of led to GPU 15 and then inside the core you change the modify the defense statement define an already built into 15 instead of GPIO 15 you just mentioned only 15 save the code and then click on upload once you see the compiling messages compelling message and then a dots you see long lines now you press the boot button now the code is uploaded and then you can see the result the LED connected at GPO 15 is blinking thank you for watching
