Today MEMS is common acronym among engineers. Therm MEMS stands for micro-electro-mechanical system and was started to use in 1980sin USA. MEMS are called system because they are not only sensors bu also contain electronic circuitry inside which conditions sensor signal. Simply speaking MEMS is usually a chip device which integrates mechanical elements, sensors, actuators […]

SPI (Serial Peripheral Interface) is one of the on-board inter-IC communication interfaces. It was introduced by Motorola, Inc. (Freescale Semiconductor). Because of its simplicity and generality, it is being incorporated in various peripheral ICs and ranks with the Philips IIC-bus. The number of signals of SPI, three or four wires, is larger than IIC’s two […]

Lets recap on the different types of

In this tutorial, we will consider the following unity feedback system:

The three-term controller
The transfer function of the PID controller looks like the following:

where Kp is the proportional gain, Ki is the integral gain, and Kd is the derivative gain. First, let’s take a look at the effect of a PID controller on the closed-loop system […]
