The stupid thing is, there is no rule that makes sure that right pin or the left one of your power socket is the phase. There are many rules for electricity, why not for this? Continue reading ‘Electronics basics (high voltage)’
Hallelujah! My Arduino kit arrived it was a really far way for it, it was shipped from Hong Kong.
It was seized for one week by customs office in Germany and, now its arrived at my workplace. The package consists of tiny little packages with following content: Continue reading ‘Getting started with arduino Part II’
Calculating LED resistor value, this is very easy and the most of you had this in the school.
A typical LED requires 20 mA and has a voltage of 2 V across it when it is working. The power supply for the circuit could be 9 V – Block battery.
For the right calculation you need three values:
1. Power supply (Your Battery 9 V)
2. LED voltage (2 V)
3. The current flowing (20 mA)
