Arduino has decided to further develop its catchy Nano project in the direction of more power. Nano Every is the simplest of the new series as it doesn´t include any sensors nor connectivity solution, however still significantly more powerful than standard Nano (50% more program memory and 2 times more RAM). Above characteristics make it perfect for projects of small devices with more advanced functionalities, such as audio processing or robotics.

Characteristic:
-100k OHM kΩ - Linear potentiometer 100k Arduino
-Tolerance: +/- 20%
- Power: 0.125W

Isopropyl alcohol is used for cleaning: - of electronic devices such as contact tips (such as those of ROM cartridges)
- tapes magnetic and disk heads (such as those for audio and video recorders and floppy drives)
- laser lenses on optical disc drives (eg CD, DVD) and removal of thermal paste of heat sinks and integrated circuit packages (for example: CPU)
-of the keyboard and LCD screen
-Usefully used to clean photographic lens lenses and contacts of electronic devices as it leaves no marks and is quick to evaporate.
