Thank you!

Sorry for the stupid question, but what is the difference between a switching regulator and a voltage regulator?

Sorry, I may not have structured my question correctly. I have attached a schematic and an image of it to this post. The LED that I am referring to is called LED Standby

Hello,

I am trying to create a circuit that will run of 13.5v, with an on off switch. I would like to have an LED light up when it is plugged in. I was planning to use a 600 ohm resistor connected to the led in a parralel circuit with the switch and the rest of the components. It occured to me that this would resolt in major excess heat and energy loss, even when the device it turned of.

Is there a way to reuse stored energy, such as a capacitator?

Thanks you,

Sasha

I was connecting rx to rx, tx to tx, resetto reset, and also connecting the two grounds. Could you please tell me the correct way to wire it?

Yes, i have attached an external power source while doing so, what's more, when reset, gnd and rx are connected,(All of them have to be connected,i've tried) the l surface mount led's that are power, pin 13, rx and tx start azy and going crazy and blinking, even when the other board is running only a blink sketch)

Thanks, I have heard that you can program an arduino without an ftdi chip, i.e. a mini, using an uno. I have tried to program the nano this way, but to no avail. Would you have an suggestions as to how i could achieve this?

Thanks for the response,

Yes i have tried the lead on something else, it works fine.

If i power it externally and plug it in, the computer can't find it

Try leaving out the If(Serial.Available() > 0) and then maybe add a 5 millisecond delay. Not sure if you need the delay though, try it with the delay and without

Hey Guys,

So, I've had a Arduino Nano or a while, used it a couple of times and it worked fine. Recently, Whenever i connect it to the computer with a usb cable, It doesn't turn on. The Led's stay off nothing goes on. However, if i connect a battery to the Vin and GND Pins, it works fine. I know the usb cable works because I've used it before fine. If anyone can help, or provide another way to program the Nano i would be grateful!

Thanks,

Sasha
