What Fruits and Vegetables Can Be Used to Light Up an LED Light and Which Ones Can't?

The fruit battery works because the fruit is acid. The typical fruit used is a lemon, but other citrus can be used - oranges, limes, grapefruits. I do not know about citrons and pomelos, but I would say probably. The links also say that potatoes and apples work. I would guess tomatoes might be good, and that eggplants, plums, onions, and pineapples might work as well. I would not expect much from carrots, melons, cucumbers, figs, cherries, zucchini, and dates. Oh wait, eggplants might be basic so maybe they should be scratched from the list. This is making me hungry for a really weird fruit salad, but maybe you can be the one to go the grocery and just pick out a few things to try?

1. Choose which led that will light up, (Digital circuit)?

So it sounds like what you are describing is you have one button that acts as a clock, and two switches that act as data... Or more accurately one switch is a one bit address and the other is one of bit data.That should be enough to get you started, but I will go a little further. You have two outputs, which are changed depending on the input data, at the clock edge. That means you need at least two latches. You now need to figure out what the truth table of the input data is to present the right level to the D inputs of the two latches. Once you have that, you can generate the appropriate logic circuit and present the clock. Using two 2-1 multiplexers makes it simple, shown below, but do not look if you do not want to cheat. simulate this circuit - Schematic created using CircuitLab.

2. My Computer LED light comes on but wont boot?

try connecting it to a visual demonstrate unit, your demonstrate might have merely went undesirable, if it did you may merely use the visual demonstrate unit or have the demonstrate replaced. Ebay is a robust place to discover a sparkling demonstrate for a stable cost if your a do it your self kinda individual, if not take it to a small computing device shop, not a huge container shop

3. What kind of led light bulbs do you need to grow weed?

Im not sure NASA had weed in mind when they developed LED lights for growing indoors, but a good source of low energy UV lights does the trick.. see the reference,, they are not cheap, but im sure you will want the best for your weed.. consider good fertilization also good luck and get a license or move some where its legal. If planning on a large scale you may want to generate your own electric power and some get curiuos when your electric bills are 6 times expected ??

4. What's the purpose of the RED LED light in the camera when you focus?

If you mean the red light in the viewfinder it lets you know when the camera has focused and/or which part of the frame is in focus. My camera has 'catch in focus' so when focusing manually the light flicks on to say correct focus has been achieved.

5. I have HP probook 4530s with HP HD webcam. Is it possible to turn off indicating led light next to webcam?

It is possible and can be done through root access. A real-time security software is all you need to alert you and prevent any stealth monitoring of your laptop webcam's LED light

6. What to do when my computer LED light blinks, then after random shut down stays on?

may be a deadly disease. Run virus scans, ascertain the antivirus is as much as date and you have a firewall. Does slightly window pop up earlier it shuts down, with a countown til shutdown time? if so, bypass to start > Run, then variety "shutdown -a" (without fees) to abort the shutdown. this would possibly not restore the undertaking, yet a minimum of it provides you with sufficient time to run scans. whether it is a deadly disease even with the shown fact that, it could have been wiped out once you reinstalled abode windows. except you have a partitioned no longer common force, and you saved your guy or woman data and basically erased abode windows records. or you subsidized up the data directly to an exterior storage gadget and then positioned them back on the laptop. Then the virus ought to be around and could have unfold on your C force... And it is a power grant undertaking, get it appeared at by utilising a expert. sturdy success, ;)
