Most people are familiar with solder as that is the main ingredient and the visible result for creating reliable electrical connections and connecting components to a printed circuit board (PCB). But soldering requires clean surfaces without any oxidation and impurities. This is where soldering flux comes to save the day! Soldering flux is a chemical substance that cleans and prepares surfaces to be soldered by removing oxidation and impurities and…
If you have soldered before, you might have encountered situations in which the solder doesn’t “want” to stick to the contacts or even flow where you intended. When soldering, any amount of oxidation and impurities can make the process more…
Microcontrollers are quite versatile devices. Not only can they process data, but they can interact with the “real world”. This means that they have to work with external devices and sensors or sometimes just a simple LED needs to be…
The Arduino Uno is a versatile piece of hardware that can turn any hobby project into a technical marvel. We can assume that since you are here you are at least familiar with the platform, but you may have questions…
Multimeters are used for a variety of tasks and can provide crucial information when you’re wiring something in or diagnosing a device. Most commonly, they’re used for measuring voltage, resistance and current, but some multimeters have additional capabilities like diode…
