In an effort to provide the best possible development experience to Stratify OS developers, I have recently evaluated various integrated development environments and source code editors for their suitability in microcontroller programming including Arduino, mbed, etc. I started with some must have criteria.

Choosing the Right Solder
The choice of the right type of solder for electronics projects and PCB prototyping is actually an easy one despite there being hundreds of options. There are three things you need to look at:
ADC Signal Conditioning
Analog signals typically are not ADC friendly, but they can be with some relatively simple circuitry such as a low pass filter and amplifier. The goal is to have the analog signal cover the entire range of the ADC. For example, if your input goes from 0V to 1V and your ADC measures from 0V to 3V, you will need to amplify the input to take full advantage of the ADC. Voltage scaling seems easy enough but you also need to make sure the frequencies you are measuring are low enough for your sample rate which is where filtering comes in.
Analyzing Op Amps
Operational amplifiers, or op-amps as they are affectionately known, are very useful when designing embedded systems and relatively easy-to-use. If you know just a few of the basics, you can design and analyze op-amps like a boss.
Including Arbitrary Binary Data in Embedded Applications
When creating firmware programs for microcontrollers, I regularly need to include to small files such as fonts, bitmaps, or lookup data. The best way I found to do this is to embed the data directly in the binary file.
