This process is made really simple using the Teleduino sketch for your ethernet enabled Arduino. Haven't heard of Teleduino? That's cool, you may want to take a look at Arduino Control via a Web Service with Teleduino to get yourself started.
This tutorial will guide you through the process of attaching a LDR (Light Dependant Resistor) to your Arduino, and provide some example Teleduino API calls to:
- Fetch the value of an analog input
- Fetch all inputs with a single API call
If you get stuck on any of the steps, or if you feel that there is a step that could be explained better, please leave a comment so that we can improve things.
Let's get cracking!
Step 1: Parts Needed and Circuit Diagram
The need the following parts to complete this tutorial:
- Breadboard (optional, but makes prototyping much easier)
- 10K Resistor
- LDR (Light Dependant Resistor)
- Some hookup wire
Take a peak at the attached circuit diagram. It shows how the components need to be connected. Pretty simple!
Let's get it all together!
