Project description
Hardware preparation: Arduino UNOx1 Ethernet shield W5100x1 USB cablex1 Photoresistor sensor Modulex1 Jumper wires several Bread boardx1 Please note:This project needs to connect Arduino to Cayenne IOT platform firstly, to learn how to setup arduino, please visit : http://osoyoo.com/?p=5407 Step 1: Hardware Setup Connect your Photoresistor with Uno as per connection graph A couple of notes before you get started: The Photoresistor uses analog output, so you will need to use the analog pins on the Arduino.In this example, we are using a 5v power supply from the Arduino, but we could use the…
