Resistor Color Code Chart

This is a resistor color code chart. This was the one I used at the beginning until I memorized it.

For example a Brown, Black, Red and gold is a 1K resistor with a 5% tolerance

555 Timer

 

A 555 timer is one of the easiest and one of the most important circuits you will learn in circuitry.

That’s why this weeks “Project of the Week” is a simple 555 Timer circuit. Over the next 6 pages, I will show you how to build it step by step.

 

 

Electrical Engineering

What I have learned about Electrical Engineering is that it is an interesting work sector to get into. This is because technology is becoming more advanced each year, which means that your learning never stops. I’ve also learned that most workplaces require a computer technician which falls under Electrical Engineering. The work section of Electrical Engineering that I’m focusing on is Electronics. What that would entail would be me fixing computers or any electronic device and not design. What I mean by that is I’m not going to be the one who engineers something; I would be the person fixing the hardware that has already designed.
