"The servo motor is widely used in model hobbyist such as airplane R/C model for moving the rudder, ailerons, elevators and acceleration control or in the car R/C model for steering and acceleration control. In this tutorial we will learn how to control the servo motor as well as the simple close loop control algorithm for this servo motor."

This week, PyroEDU’s Analog Electronics course is featuring a lesson on RLC filter design. Here’s a quick intro of what this PyroEDU lesson is all about:

When we combine together a low pass RL and a high pass RC filter, the result is an RLC filter which filters both low and high frequencies out of a signal. In this lesson, we will learn how to build an RLC filter, see what formulas are necessary for designing an RLC filter and experiment with understanding the effect an RLC filter has on an audio signal.

"This article shows how to do a simple communication via a RS232 interface with a PIC microcontroller. RS232 is a standard for a serial communication interface which allows to send and receive data via at least three wires. With the RS232 interface it is possible to setup a connection between a microcontroller and a PC or between two microcontrollers."

"The Haptic Creature has three degrees of freedom through which it communicates its emotional state: a pair of ears, which vary in stiffness; lungs, which simulate breathing; and a purr box, which renders a vibrotactile “purr”. The robot has an array of force sensors across its body to sense touch and an accelerometer to sense movement."

"A few weeks ago I needed an Arduino compatible Micro SD adapter but didn’t want to wait for one to arrive in the post so inspired by the breadboard ghetto Micro SD socket I knocked up a mini shield using a bit of left over stripboard and a SD to Micro SD adapter."

"I have a few old N64 controllers lying around and figured that it would be pretty cool to use them to control other things. In this article I will describe in detail every step I took to achieve this. I’ve used a PIC microcontroller, but it should not be too hard to port the code to any other architecture."

"This is a quick guide with a bit of extra info that I’ve learnt along the way on how to use the L293D with the Arduino, showing that we can: A) Use a supplemental power source to power the DC motor, B) Use the L293D chip to drive the motor, C) Use a switch to change the direction of the motor."

It’s that time again! We’re releasing another lesson on PyroEDU for our Analog Electronics course. This week the lesson is about Passive Analog Filters. Here’s a quick intro of what this PyroEDU lesson is all about:

The most basic passive analog filter comes by combining together a resistor and a capacitor or a resistor and an inductor. In this lesson we are going to learn how to build and design some basic RC and RL filters and see the effect of these filters on a simple audio signal.
