Introduction
Type errors in Arduino refer to errors that occur when the data type of a variable or an expression does not match the expected data type. These errors can occur when a variable is declared with the wrong data type, when a variable is used in an expression with an incompatible data type, or when a function is called with the wrong number or type of arguments. Type errors can be difficult to debug, as they can cause unexpected behavior in the program. This article will discuss the different types of type errors, how to identify them, and how to fix them.
Solution
A Type Error in Arduino is an error that occurs when the type of a variable or an expression does not match the type that is expected. This can happen when a variable is declared with one type, but is used with a different type. For example, if an integer is declared, but is used as a string, this will cause a Type Error.
About your specific bug you should
‘dht’ does not name a type
That means you have the word dht that is not at a place where the compiler could understand what you mean.
how do i change it to a type?
You do not want to change it into a type, you want to solve the compiling issue you’re getting.
what does a type mean?
You should read the K&R on the subject. A type is a rule that constraints you into making code that is coherent.
You should copy in your question the full error you’re getting, for us to better help you.
Let’s assume the error is on the following line:
#include <dht.h>
dht DHT;
The compiler does not know what is the dht, as it has never seen that being defined before. I assume, dht.h shall be a header to be included that needs should contain dht type definition. You should look if you have dht.h in your filesystem, and push it in your sketch’s directory. And finally change the #include <dht.h> into #include "dht.h", so it looks up the dht.h in your local directory.
EDIT: I’m sorry I don’t think I can’t help you here more than what I just said. The problem is that you don’t understand what I’m telling you to solve your problem, and explaining it to you would be giving you a C programming lesson. So you should first begin to read the K&R, go to some C/C++/Arduino programing courses (maybe in your local hackerspace?), and/or ask your friend to help you out and explaining to you what is happening.

What Does Type Error Mean in Arduino?
Type errors in Arduino are errors that occur when the type of a variable or an expression does not match the type that is expected. This can happen when a variable is declared with one type, but is used with another type. For example, if a variable is declared as an integer, but is used as a string, a type error will occur.
Type errors can also occur when a function is called with the wrong type of argument. For example, if a function is expecting an integer, but is passed a string, a type error will occur. Type errors can also occur when a function is called with the wrong number of arguments. For example, if a function is expecting two arguments, but is passed only one, a type error will occur.
Type errors can be difficult to debug, as they can be caused by a variety of different issues. It is important to check the types of all variables and arguments to ensure that they match the expected types. Additionally, it is important to check the number of arguments that are passed to a function to ensure that the correct number is passed.
