18 sie 2013 · I have the problem that I get audio noise from the power supply coil at hearable frequencies (like 10kHz). I changed the frequency to the full 31.25 kHz of Timer0 from a AtTiny85 at 8MHz, but I'm not sure what the maximum supported PWM frequency for a 5050 SMD LED is.
7 kwi 2018 · My goal is to control an LED light using a limit switch. When first press the switch, the light turn on and when release the switch the light stay on until the switch is pressed again then the light will turn off.
20 gru 2013 · Unless you have a great deal of interest in dimming, your best option if you have 200W of LEDs on the circuit would be to use a switch. The limit comes from the interaction of the power supply circuits internal to "dimmable" LEDs/CFLs and the dimmers that can be used with them.
18 mar 2009 · #1 had NO push pulls or additional switching installed during Led Zeppelin. You will never see him doing any pushing or pulling only turning. A push/pull was added in the bridge tone control position sometime post Led Zeppelin, exactly when isn't clear.
A timer switch is convenient to automatically turn on your lights at certain times. It doesn’t matter whether you want to control your outdoor lighting, decorative lights or aquarium lighting. But when using LED lamps on a timer, some problems may occur. Here you’ll find out what to pay attention to when choosing a timer switch.
The LED minimum load rating for LED loaded dimmers is usually given in the number of lamps instead of Watts (W) or Volt-Amps (VA). Lutron C.L Dimmers can control up to 17 bulbs and is the only dimmer UL listed to control mixed loads (different types of bulbs, such as LEDs and halogens, on the same circuit).
A rotary wheel is used to adjust the brightness of the connected LED lamps. By pressing the rotary wheel, the light is switched on and off. For the other variant you can adjust the brightness with the slider. As an alternative form, flush-mounted dimmers are also available as touch dimmers.
