A solenoid moves an iron core through the center of a wire coil when current flows through the coil. It is different to a relay which uses an electromagnet with a fixed iron core. Typical voltages used in solenoids are 12 and 24 volts. Some solenoids are controlled by pneumatic and hydraulic pressure instead of electricity. Solenoid Actuators Solenoids actuators have a spring in the base at the base of the iron core. When current flows through the solenoid, the electromagnetic field overcomes the spring resistance, and pulls the rod Read More

One of the main objectives of using functions in a program is to save some memory space, which becomes appreciable when a function is likely to be called many times. However, every time a function is called, it takes a lot of extra time in executing a series of instructions for task such as jumping to the function, saving register, pushing arguments into the stack, and returning to the calling function. When a function is small, a substantial percentage of execution time may be spent in such overheads. One solution Read More
