Arduino – Communicate With Server – Part 3 – Web Based Panel

This is the code for the web based panel (web based UI) that will display the data received from arduino or can send some command to the Arduino All communications are done through a server (web server) The frontend code <?php date_default_timezone_set(“Asia/Kolkata”); $conn = mysql_connect(“localhost”,”root”,”xxxxxxxxxx”); if(!$conn) {     echo “Error: failed to connect DB”;   … Continue reading Arduino – Communicate With Server – Part 3 – Web Based Panel

Arduino – Communicate With Server – Part 2 – Server Code for Saving Data

This article shows the server side code for a server which is gathering or sending data by polling method to an Arduino device. This method or code is putting less load on the server (compared to socket) but data transmission is slower than socket. <?php date_default_timezone_set(“Asia/Kolkata”); $conn = mysql_connect(“localhost”,”root”,”**********”); if(!$conn) {     echo “Error: failed… Continue reading Arduino – Communicate With Server – Part 2 – Server Code for Saving Data
