Wheatstone Bridge Circuit Theory and Principle. For measuring accurately any electrical resistanceWheatstone bridge is widely used.
There are two known resistors, one variable resistor and one unknown resistor connected in bridge form as shown below. By adjusting the variable resistor the current through the Galvanometer is made zero. When the current through the galvanometer becomes zero, the ratio of two known resistors is exactly equal to the ratio of adjusted value of variable resistance and the value of unknown resistance. In this way the value of unknown electrical resistance can easily be measured by using a Wheatstone Bridge. The general arrangement of Wheatstone bridge circuit is shown in the figure below. Now, from Wheatstone bridge circuit and Now potential of point B in respect of point C is nothing but the voltage drop across the resistor Q and this is Again potential of point D in respect of point C is nothing but the voltage drop across the resistor S and this is Equating, equations (i) and (ii) we get,

There are many references to op amps out there, but here, we're going to concentrate only on those features that are important to electrochemical applications.

Java is a general-purpose, concurrent, class-based, object-oriented, high-level programming language and computing platform first released by Sun Microsystems in 1995.
It is related in some ways to C and C++, in particular with regard to its syntax, and borrows a few ideas from other languages. Java is designed to be simple enough that many programmers can quickly become proficient in the language. It is one of the most popular programming languages in use, especially for client-server web applications. Some popularity indexes show that Java holds the top spot with C. This programming language is the underlying technology that powers utilities, games, business applications, and other software. The focus of this article is to select some of the finest Java books which help programmers master all aspects of this language. Software Development from John Sonmez's Perspective.

Céu: a high-level programming language that runs on Arduino. The link you provided gives a very similar example to mine and "assumes the do_something() execution time is well below the system tick period and that my_thread() is not preempted": An obvious solution is to write something like this: msg_t my_thread(void *param) { while (TRUE) { do_something(); chThdSleepMilliseconds(1000); /* Fixed interval.*/ }} This example works well assuming that the do_something() execution time is well below the system tick period and that my_thread() is not preempted by other threads that could insert long intervals.If the above conditions are not satisfied you may have do_something() executed at irregular intervals, for example:
