There are two main modes to run the Let's Encrypt client (called Certbot):

Webroot is better because it doesn't need to replace Nginx (to bind to port 80).

In the following, we're setting up mydomain.com. HTML is served from /var/www/mydomain, and challenges are served from /var/www/letsencrypt.

A simple set of scripts for getting output from an Arduino to act is input for Python.

Install python3
Install pyserial
adjust monitor.py to include your COM location as the COM variable (ie COM3 or /dev/ttyACM0)
run with python monitor.py --monitor (You may have to run as root on linux)

// jQuery
$(document).ready(function() {
  // code
})

	Under lspci -vv, I saw my wifi card bcm43228 is using wl module, but it is working weirdly, so I go inspect dmesg and found:
	[ 17.135645] wl: module license 'MIXED/Proprietary' taints kernel.
	[ 17.135648] Disabling lock debugging due to kernel taint
	[ 17.137273] wl: module verification failed: signature and/or required key missing - tainting kernel
	[ 17.227089] wlan0: Broadcom BCM4359 802.11 Hybrid Wireless Controller 6.30.223.248 (r487574)
	[ 17.315644] wl 0000:03:00.0 wlp3s0: renamed from wlan0

	linux is loading the wrong device for my wifi card.
	so I search online and found https://ubuntuforums.org/archive/index.php/t-2209676.html
