Components
To build your Embedded device, you will make use of all kinds of components which you connect to your microcontroller. These components can be sensors, actuators, displays, etc. In this section, we will discuss the most common components and how to use them.
Light Dependent Resistor (LDR)
Using a LDR you can build an application which will respond to the amount of light in the environment.
DHT 11
If you want to measure temperature/humidity "ok"-accurate, you can use the DHT 11.
LCD display
To display some information from your device you can use an LCD-display.
Push buttons
Give your users some input; use a push button to allow interaction.
