Building a Christmas Tree (Part 1)
It's Christmas time again. Let's build something Christmassy like a programmable LED Christmas tree.
LDR Modules
LDRs are an easy solution to react to brightness changes. Let's look at corresponding Arduino modules.
Light Dependent Resistors
Light dependent resistors are an easy solution for reacting to brightness changes. Let's discover their properties!
