LED Dimmer for 220-240V Lamps HowTo Posted Monday, 19 Jan by HowTo, Light. This article is primary for those in a country with a 220-240V~50Hz electrical system. Do you know how it is when you sit in a room, somebody comes in, turns the light on and it becomes way too bright? the dimmer is made for 220-240 Volts dimmable LED/ESL with 3

Arduino Uno: Sensor shield powering multiple servos

/23/2012So no matter what the power source I'm putting into the Arduino (volts-wise) I can plan to use a resistor that would be sufficient for 5V, correct? Appreciate all responses, guys. Getting more and more comfortable with all this. 1. 7) / 220 = 7. 2 mA So each LED is only getting 7 mA rather than 15 mA and is thus less bright. Now you could

Arduino AC measurements. Tomi Engdahl; March 15, 2015; DC power measurement is relatively simple as the equation is simply watts = volts x amps. For AC power measurement, the power factor (PF) introduces complexity as watts = volts x amps x PF. for this: a traditional 12V transformer gives out safe 12V AC output usually at several
