Description

This is the second course in the DIY Lab Equipment with Arduino series. After we learnt the basics in the first course, now we APPLY the knowledge to measure and control the temperature for our experiment setup or project. Temperature is essential in almost any experiment and it is important to record it continuously. This is why we directly employed SD card module to save the records so that we can retrieve them and put them in Excel for example. We also included how to send the data to Google sheet so that online monitoring can be done anywhere. We also added OLED display to show the measurements so that the system can be used easily independent from the computer.After learning temperature measurement, we moved to explain different ways of heating and cooling. We made a complete setup to measure the temperature and use it to control heating and cooling of water as an example of experiment setup. We employed PWM to precisely control the temperature. Similar setup can be applied in different ways to fit to our experiment. Like other course, we use off-shelf components that are readily available at low cost.During this course, we practice how to utilize available codes from the internet or library examples and fit them in our project with minimal coding experience. If you have no knowledge about coding and Arduino, it is highly advised to take the first course (DIY Lab Equipment with Arduino-Part 1-The basics).In the next course we will learn about liquid handling that includes the properties and use of different pumps and how to make your own pump to use it to control liquid transfer.
