In this example we are declaring an int variable calledvariableand setting it equal to the number four. Integer variables use two bytes of memory, so they can hold 216different numbers (up to 65,536). But the int data type can hold positive and negative values, so the range is actually ...
Below is a list of the data types commonly seen in Arduino, with the memory size of each in parentheses after the type name. Note:signedvariables allow both positive and negative numbers, whileunsignedvariables allow only positive values. boolean(8 bit) - simple logical true/false byte(8 bit...
Insert Variables This window will let us edit the elements of the Enum. As the picture shows, we can insert, delete, or move up an element in this window. If we want to insert an element in the Enum, simply click on the insert button. It will let us enter the name of the variabl...
This feature is essential for global and static variables accessed from different threads, and program correctness will be preserved. Generally, using atomic type objects is an alternative to locking objects such as mutexes and their standard API functions like mtx_lock, mtx_unlock etc. The ...
term PID stands for proportional integral derivative and it is one kind of device used to control different process variables like pressure, flow, temperature, and speed in industrial applications. In this controller, a control loop feedback device is used to regulate all the process variables. ...

Pressure sensors are used to measure the pressure exerted on any object or at any point, it can also be used to indirectly measure other variables such as fluid/gas flow, speed, water level, and altitude. Vision and Imaging Sensors/Detectors ...
