Whether you’re building a robot, actuating a doorknob, or just need any other electronically controllable physical movement, hobby servos will usually do the trick thanks to their availability, low cost, and relatively high precision. But how do you control one or even two dozen of them simultaneously through your computer?

Adding USB support to your project isn’t the easiest thing to do. You have to worry about the driver stacks on the host computer and a bunch of other details which make the USB interface really unfriendly to the hobbyist especially when compared with the simplicity of a serial or parallel interface. Because of this, […]

The MAKE Controller is similar to an Arduino except it uses a different Atmel AVR chip. However, the board aims to make it easy for the hobbyist to use the surface-mount chip by including all of the supporting circuitry such as oscillators, voltage regulator, etc. The board was created by the people who write the […]

This great video shows you how easy it is to wire-up a potentiometer to an Arduino microcontroller board, read the resistance value, and then control a standard hobby servo in unison. The simple software reads the analog to digital converter to read the pot value and then does a simple calculation to arrive at the […]

Field Programmable Gate Arrays, or FPGAs, are high-speed chips which are filled with thousands of structures called logic blocks. These blocks allow you to build, using a specialized electronics programming language like Verilog or VHDL, a custom circuit on the chip to do whatever you need done in your circuit. The FPGA offers much of […]
