In this project we introduce easy to build, miniature servo controller. This miniature servo controller system is ideal for most of the robotic and mechanical projects. Some of the most notable key features of this project are:

  • Tiny PCB design (35mm × 33mm aprox.) using standard through-hole components.
  • Support for both analog and digital control interfaces.
  • Compatible with most of the servo units.
  • Low cost due to small amount of components.

Ejberg.dk has developed this project for a simple ATtiny2313 based servo tester.

This device lets you test servos by varying the pulse width between limits of 0.8000 ms and 2.2000 ms selectable through the use of four buttons.

While the schematic shows an Atmel AT90S2313, the circuit will work with the popular ATtiny2313 using version 2.05 of the code downloadable from the ejberg site. He also has another version of this tester known as the ServoTester2 which uses the ATmega16P.

Searching for a reliable wireless solution for your project can be a real pain if you’re not familiar with current wireless standards, data rates and reliability. The Xbee Modules that we will use in this article are widely available, use a very reliable wireless transmission protocol and have sufficient datarates for most hobby projects.

This article will show you how to build a basic wireless input and output system in the form of a single transmitter and single receiver. Communication will be one way to keep things simple with two xbee modules being used for the wireless link. In the end, a small trimpot will control the movement of a servo motor.

I believe that kids (and not only kids) that have their hands on electronics, wanted at least once in their lives to make an electronic keylock system for their house or room. When i was a kid, i had bought a Smart Kit Keycode lock system, and i had adapted it on the external door of my house. But this door had already the automatic-release mechanism. I only had to find which wires actuate this mechanism and hook the relay of the kit in parallel to this.

Then, i discovered that making a key-code circuit, is simple, very simple. As a matter of fact, so simple, that i designed this very simple key-code circuit, similar to the one from smart-kit but much better (mine had automatic reset operation when wrong code was entered), which took me only a few hours to design. Not to mention the microcontrollers… But why don’t i have a keycode-lock for my apartment’s door? Simple because it is expensive and needs a great mod on the door or frame.

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.

The servo motor basically is a high quality geared DC motor equipped with electronic circuit for controlling the DC motor rotation direction and position. Currently there are two types of servo motor available on the market, the first one is called standard servo and the other one is called continues servo; standard servo can rotate to maximum (clockwise or counterclockwise) of 120 to 180 degrees while continues servo can rotate up to 360 degrees in both direction.

The servo motor and the dc motor have one simple difference: one is inherently controlled while the other is not. This guide goes through the specifics of when to use which type of motor. [via]
