This document provides instructions for connecting light dependent resistors (LDRs) and a temperature sensor to an Arduino board. It explains that you need an Arduino board, breadboard, resistor, and LDR. For the LDR circuit, you connect the components as shown in a picture and power the Arduino board. For temperature sensing, you similarly connect the Arduino, breadboard, resistor, LDR, and TMP36 temperature sensor in the correct order. The document also mentions programming the Arduino board once the sensors are connected.
