==Objective==<br />
This tutorial will teach you using two temperature sensor, that are LM35 and DS18B20, and use the OLED module to display the temperature.<br />
<br />
==Equipment==<br />
*'''[[Microduino-Core]]'''<br />
*'''[[Microduino-FT232R]]'''<br />
*Other equipment<br />
**Breadboard Jumper <br />
**Breadboard <br />
**LM35 temperature sensor<br />
**DS18B20 temperature sensor<br />
**Microduino OLED<br />
**USB cable<br />
<br />
<br />
==First experiment (LM35 temperature sensor)==<br />
<br />
<br />
==Schematic==<br />

LM35 and DS18B20 use the same pin connection.<br />
<br />
OLED IIC connection method:<br />
{| class="wikitable"<br />
|-<br />
! OLED !! Core !! Core+<br />
|-<br />
| SDA || A4 || SDA<br />
|-<br />
| SCL || A5 || SCL<br />
|-<br />
| 3V3 || 3V3 || 3V3<br />
|-<br />
| GND || GND || GND<br />
|}<br />
<br />
==Program==<br />
LM35 and DS18B20 use the same program.<br />
<br />
Refer to MicroduinoOLEDThermometerLM35-DS18B20.ino<br />
<br />
<br />
==Debug==<br />
Step 1：Copy the code to IDE and compile it<br />
<br />
Step 2：Set up the circuit, as follows:<br />

Step 3：Download the program and then run it.<br />
<br />
Step 4：Observe the OLED module. Find a hot object to close the temperature sensor, the OLED will display the value.<br />
<br />
<br />
==Result==<br />
After LM35 sensor near the heat source, the OLED displayed value will rise, leave the heat source temperature will gradually reduce.<br />
<br />

Step 3：Download the program and then run it.<br />
<br />
Step 4：Observe the OLED. Find a hot object to close the temperature sensor, the digital tube will display the value.<br />
<br />
==Result==<br />
After DS18B20 sensor near the heat source, the digital tube displayed value will rise, leave the heat source temperature will gradually reduce.<br />
