The Tinker Foundry

Code used in this demonstration: Python Server Code: # Tinker Foundry Example Python Code # Python web server to work with ESP32 POST request # This runs on your local computer, connected on the same WiFi network as your ESP32 controller from http.server import BaseHTTPRequestHandler, HTTPServer hostName = "192.168.xx.xxx" # use ipconfig in console (command prompt) to get the "IPv4 Address" of this machine serverPort = 8080 # BaseHTTPRequestHandler class is used to handle the HTTP requests that arrive at the server class MyServer ( BaseHTTPRequestHandler ):     def do_POST ( self ): # handle POST request from ESP32 (or anything else, really)         content_length = int ( self .headers[ 'Content-Length' ]) # Gets size of data         post_data = self .rfile.read1(content_length) # Gets data         print ( "Post Data: " )         print (post_data.decode( 'utf-8' )) # This is the message from the POST request         self .send_resp

Below is the code used in the video to have ESP32 request time from an NTP server and update the internal RTC clock. // The Tinker Foundry ---  https://youtu.be/c6r9kECS6RQ // ESP32 Code for testing RTC - real-time clock updated from an NTP (network time protocol) server over the Internet // Use NTP to get Coordinated Universal Time (UTC) and adjust to local time/date // ESP32 will connect to an NTP server and send a request packet // In response, the NTP server will send a time stamp packet #include <WiFi.h> // The usual for ESP32... #include "time.h" // ESP32 native time library to handle NTP server connectivity and synchronization   const char * ssid     = "********" ;   // input your wifi name const char * password = "********" ;   // input your wifi passwords   // set up the NTP server name const char * NTPServer = "time.google.com" ; // for our example, let's use Google's public NTP - see developers.google.time for m

Accompanying code for Arduino IDE, as shown in the video, below. // ESP32 Code for testing IFTTT // Sends a request to STATUSUPDATE (or whatever you define) applet which will trigger an e-mail being sent #include <WiFi.h> #include <HTTPClient.h>   const char * ssid     = "*****" ;   //input your wifi name const char * password = "*****" ;   //input your wifi passwords   // set up server name with trigger the event defined in the IFTTT applet const char * server_name = "https://maker.ifttt.com/trigger/EVENT_NAME_HERE/with/key/KEYHERE" ;   void setup () {   Serial . begin ( 115200 ) ;   Serial . setDebugOutput ( true ) ;   Serial . println () ;     WiFi . begin ( ssid, password ) ;     while ( WiFi . status () != WL_CONNECTED ) {     delay ( 500 ) ;     Serial . print ( "." ) ;   }   Serial . println ( "" ) ;   Serial . println ( "WiFi connected" ) ;     Serial . print ( "Msg: Ready!
