Scam or Worth It? Do you need to be worried about having the HVAC ducts in your home cleaned? Duct cleaning has become popular in recent years, with commercial cleaning services popping up everywhere. But is the service worth it, or is it a scam?
There are lots of Arduino tutorials that make it much harder than it has to be. There are many difficult and complicated ways you can read data over the serial port, but luckily there is an easy way.
While we touched on this briefly in earlier videos, it is such an important topic I want to focus on it in this lesson. Almost all possible needs can be covered by three simple data types.
So, you need to know how to read these three data types over the serial port. The easiest way to read a string of text is using the Serial. The easiest way to read a Float is with the Serial. To practice this, lets do the following. Write a program that will promt the user for his age, for how much he weighs, and then how tall he is in feet.
Then print out a nicely formatted output that relays that information back to the user. In order to do this the first thing we must do is decide what type of variables to use for each of these three pieces of data.
To store the weight, we would just about always round to the nearest whole number so it would make sense to use an Int for this. On height, we would not normally round to the nearest foot.
In this case we should use a float, since we want the decimal numbers. So, we would then declare these variables the suitable type and then read them in using the corresponding commands. Also, remember when you are going to read data from the serial port you must do three things: This should be review as we have done this in several earlier lessons.
Try and write the program yourself, but if you get stuck you can look at the code below that I wrote for this problem."When we travelled down to Millwall in the last round, he was doing his homework on the team coach."
