Running the program

Now, you can configure your project with the make menuconfig command. You can carry out this task with the blinking project that we looked at in Chapter 1, Getting Started with ESP32.

After our program is flashed into the ESP32 board, we can use a serial program such as PuTTY or CoolTerm. For the demo, I used CoolTerm. You can download this tool from the following link: http://freeware.the-meiers.org. 

You can then open a connection to the ESP32 board. If this is successful, you will see our program output on a serial tool. You can see my program output in Figure 2-6:

Now that we've configured our sensors to read temperature and humidity, let's look at displaying this information using an LCD.
