I will show you how to install the Arduino IDE environmental for ESP 32 module so that we can use our kch six eight a four relay controller, because this relay controller is light coded by Arduino IDE, so we can firstly open this URL arduino.cc website and click the software then you can see there are many versions of Arduino download like Windows Linux and Apple Mac and Mac computer in Windows so we can download the Windows file with just a click and the cost of failure is very large. So I have already downloaded in my computer so we can just click this file to run the installer program. Click Agree and next and install I have installed this further as default so this will take a lot of time Okay, now the Install Complete, we can click close and double click the icon on the desktop. Then we will open the Arduino IDE software and as this is a window we have see we can maximize and we can see the toy and there's a pod there is no ESP 32 pod. So we need to configure the pod firstly and we can see this is the URL for Insta pod.
