Sending Light Sensor Data from Arduino to Thingspeak

I am using an Arduino to update ThingSpeak with lighting data in my office. The Arduino samples an analog input pin with an LDR connected to it, converts the sample into a lux measurement and then sends the lux measurement to my ThingSpeak channel using the HTTP protocol.

Thanks for sharing with us! I was having some trouble on sending float data to thingspeak and now I have a different approach to solve it. Thanks again, Sir!
