We will show you how to build a speed control for only a fraction of the cost of those available commercially. This speed control uses a low-cost Pic12F675 micro controller and a few other basic components (resistors, capacitors, transistors, diodes and a regulator.) Below is a photo of the speed control connected to the motor …
Diodes have the following properties: They only allow current to flow in one direction They have a specific voltage drop, which can be taken as a constant for most circuits https://web.archive.org/web/20090224113643/http://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-2757683140936137&dt=1235387152210&lmt=1612436233&output=html&slotname=6542966663&correlator=1235387152210&url=https%3A%2F%2Fmayothi.com%2Fdiodes.html&frm=0&ga_vid=861307647.1235387153&ga_sid=1235387153&ga_hid=918268353&flash=0&u_h=864&u_w=1536&u_ah=834&u_aw=1536&u_cd=24&u_his=8&u_nplug=3&u_nmime=4&dtd=M&w=728&h=90&xpc=uGwQh3BKCc&p=https%3A//web.archive.org A diode is represented with the following symbol: The diode above will pass current flowing from left to right, but block current trying to …
I like the simplicity of my VW Polo’s standard radio unit, but I really need a bluetooth handsfree kit and iPod connectivity. I first tried an after-market kit that added the needed functionality to the factory radio, but after returning it for the third time (each time waiting more than a month for the replacement …
A basic circuit Here is an example of using Ohm’s Law for a basic circuit (see the electronics introduction if you’re not familiar with Ohm’s law.) We have a resistor of 4k7 (4700 Ohm) connected to a 5V supply, what is the current flowing through it? https://web.archive.org/web/20090224113643/http://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-2757683140936137&dt=1235427218282&lmt=1612436182&output=html&slotname=6542966663&correlator=1235427218282&url=https%3A%2F%2Fmayothi.com%2Fresistors.html&frm=0&ga_vid=2137999440.1235427220&ga_sid=1235427220&ga_hid=1237380667&flash=0&u_h=864&u_w=1536&u_ah=834&u_aw=1536&u_cd=24&u_his=7&u_nplug=3&u_nmime=4&dtd=M&w=728&h=90&xpc=BvwG0wKY6e&p=https%3A//web.archive.org Answer I = V/R = 5V/4k7 = 1.06mA …
Ohm’s Law Probably the most important law in electronics is Ohm’s Law. Ohms Law states that the voltage across a resistor equals the resistance of the resistor times the current flowing through it (V=R*I). Thus if you have a resistance of 1000 ohms and a current of 10 milliamps flowing through it, the voltage over …
I’ve never really liked Hyper Terminal (the communications program bundled with windows) when it comes to serial communications. Thus I decided to write something specifically for programmers / engineers to make serial communications easy. What I like about serialWizz: No need to create a new connection every time you open the program All the settings …
Background :Knoughty was written as a simple demonstration of the alpha-beta search algorithm. Because noughts and crosses is a simple game, a perfect alpha-beta search is possible and can also be done very quickly (on my Palm Zire 72, it only takes a fraction of a second to make each move.) I have written the program …
Number systems We humans (and selected Alien species) use the decimal number system. What this means is that all the numbers we write down consists of the 10 digits 0 to 9. In other words when we count and get to 9, we start again with 0. Of course to show the difference between zero …

Konnectonator is a program that plays connect four (also known as “four in a row”).The rules of the game is easy: get 4 stones in a row (horizontal, vertical or diagonal) and you win!The board consists of a 7 by 6 matrix, if you drop a stone it will fall down to the bottom of …
