| | | | | Hi lovely people! ?? In the last article we talked about the soil moisture sensor. In this article, we will take a look at how to measure temperature using DS18b20 and measure light intensity using a photocell. Step 1: Wiring up the Circuit We will be using: Arduino UNO Breadboard DS18B20 Temperature Sensor Photocell (any typical one) 4.7K? resistor 10K? resistor Jumper Wires Wire up the circuit like this: | |
