## Linear Mapping of Input Range to Output Range

Whenever you mix sensor input values and electronics, you always get a situation where the data read from the sensor needs to be interpreted or changed or scaled to be used by your control software.

Mapping or scaling a linear range of input values to a linear range of output values is as easy as: $y=mx+c$

## Voltage Conversion Hack

Have you ever wanted to convert 3.3V to 5V? Well I had to recently come up with a hack since I did not have the correct driver logic chips.

Here's how...

# Testing-made-Easy

I have been teaching Digital Systems 1 for a number of semesters during my career as a lecturer. Digital Systems 1 is all about number systems, basic logic gates and combinations of these gates which can create modules like adders, subtracters, multiplexers, flip-flops, decoders, etc.

The one thing taking up the most time when grading student designs, is testing the logic circuits they build on their breadboards. But now... It's a lot quicker.

# Voltage Regulators

I have used voltage regulators, especially the 78XX series of regulators, for a myriad of different projects. Everybody doing any project in electronics has.

I have also read a lot of articles explaining how to use these regulators and all of the articles get everything right except one crucial factor, I like to call it: The Power Dissipation issue.
