Implementing precise single shots with AVR timer

Microcontroller timers are meant to count clock cycles in hardware, and there are many ways and configurations where timers are handy. First of all, timers are meant to work purely in hardware without utilizing CPU. Secondly, timers help generate waveforms like PWM, trigger events, count the time between events, etc. But there is one use that, in most cases, is missed and not documented – precise single shots that allow generating only a single pulse shot with precise length. And this method doesn’t require CPU to be involved – just set and forget. The idea of this method lies in using fast PWM (refer to datasheet for more info) mode a bit differently. Normally in this mode timer works by counting to TOP value; somewhere in between, there is a MATCH value where timer outputs HIG and drops to LOW when TOP is counted. This way, there is a PWM signal generated. Josh came up with the idea that, in this case, we can generate only single pulse by setting MATCH value above the TOP and setting the initial timer…

Everything you need to know about diodes

Diodes are commonly used discrete semiconductor devices. It has many uses and purposes. Its operation is based on PN semiconductor junction characteristics. Depending on diode’s physical and chemical properties, it can behave very differently. Together with other electronic components diode can be used for voltage clipping, multiplying, rectifying, signal, demodulation, protection, and even more. Elektro-labs have written a pretty nice review of diode types and their common uses. The simplest and probably most recognizable is regular diode which is used in switching, protection rectification circuits. Another common diode type is Zener which is used for voltage stabilization. Here are some of the most common types of diodes, along with examples of part numbers:

Handy voltage transition indicator circuit

You simply need a simple way to test the voltage on battery-operated circuits. On the other hand, complicated circuits don’t look very attractive. So to keep things simple and low-cost, Einar Abell suggests his single transistor voltage indicator circuit. It is able to detect the transition between two voltage levels on battery. Simply speaking, if the circuit is powered from 9V battery, then it will transition from green to red indicator when voltage foes from 7.1V to 5.8V. One downside of this indicator is that it drains about 1mA of current. For any battery, this is nearly not acceptable. To avoid constant drainage, drop a push button to test voltage when needed. Pros and cons of discrete voltage transition indicator circuits Pros: Cons:

Running head How to Make Your Websites Work on 200% With SEO

Search engine optimization is concerned with the construction of the quality content and web pages so as to attract users to the website. For the website traffic to increase, there is a need to create effective and unique content which is helpful to the users. Also, the following should be considered. Captivating keyword A captivating keyword should be placed on each and every page so as to attract viewers. Also, each and every page should be different so as to make the work remain attractive. The captivating keyword should appear on the page title, URL, Meta tags, and the images. Improve the title page According to SEO specialists in Vancouver, the title page is the first thing that the viewers see whenever they look at the site. It is also the first thing that SEO shows. Therefore, the title page should arouse curiosity from the viewer and a sense of eagerness. The title page should be written using numbers and colorful letters mainly because the page title is the most valuable asset at one’s disposal for attracting customers.

Offshore Startups Development

There is hardly any need for in-house IT specialists, since virtually any IT project can be assigned to an offshore company. Indeed, consistent work of computer systems, as well as software development, can be provided by offshore specialists. The benefits of IT outsourcing are numerous and evident, and many big and small companies have already started availing these benefits. The main benefit of IT outsourcing is that allows developing businesses quicker while investing less money. Since offshore development allows spending less money, it is especially advantageous for startup companies. Keeping an in-house IT department is expensive, and most startups cannot afford it. The best solution to this financial issue is IT outsourcing. The latest research shows that small companies with less than two hundred in-house employees save thousands of dollars by using IT outsourcing services. Saying short, implementing offshore startup development strategy is much cheaper than investing in high-priced software or hardware or having in-house IT staff.
