In this tutorial, we’re going to make our very own Arduino dice circuit. This is a simple project and is great for introducing yourself to more of the basics of the Arduino. Much like the Arduino traffic lights project this project uses a variety of LEDS and resistors to make up the ...
The circuit used in this robot is very basic, I have connected the positive side of the battery and the LED bulb directly to the battery whereas the negative side is connected via the switch. I have also created a small simulation for this circuit which you cab see in this step You can...
I wanted to build a home arcade machine that could play all the classic video games as well as those console favorites. I’ve played around with arcade emulators on my PC before so I knew a little bit about how it all worked. After months of researching and reading a lot of different ...
Even the more basic printed circuit patterns appear to have a large quantity of thin copper tracks within a relatively compact area of board nowadays, and a paint brush competent at creating extremely fine lines becomes necessary. Drawing the Track Layout A simple solution would be to utilize an...
Design a home uninterruptible power supply (UPS) by using a car battery as a backup power source. This is connected to a buck-boost converter that generates a stable 12 V/5 A supply to power the Wi-Fi router, as well as a 6.5 V/1.5 A buck converter to po
In this post I will elaborately explain how to build a simple LM317 based adjustable power supply circuit using minimum number of external components. As the name suggests a variable power supply circuit provides the user with a range of linearly varying output voltages through a manually controlle...
The Arduino code here uses a Real Time Clock (RTC) that keeps track of the time of day for a few years until the internal battery runs out. The RTC circuit uses special Arduino code to set the clock time. The process for setting the RTC is quite simple andwell described on ...
Here is a photo of one homemade key and sounder that was build to look just like some of the telegraph sets that were used from 1844 to the 1950s: As you can see, this was a carefully thought-out and executed project. Many people just want to build a very simple set to become fam...
the Spring and Fall, but there can still be some pretty hot days. I have plenty of power, thanks tomy solar panelsandhome-built wind turbine. So I decided to build a small swamp cooler to keep the cabin cool. It was a pretty quick and easy build. This web site shows how I did ...
Place the open ends of the clothes pin under a window and close the window as much as possible. This should hold the clothes pin open and prevent the thumb tacks from touching to complete the circuit. If you open the window, the clothes pin will close and the buzzer will sound. ...
