Re: Help needed please

This would be easy. Get 11 switches, and each switch turns on its particular set of lights. Then have one more switch, that feeds to 11 diodes, and each one of these diodes also goes to each string. When that switch is turned on, it supplies power via the diodes to each string. When that switch is o...

Re: Button covers

I have faced this exact same issue, and my solution involved some aluminium rod from a hobby supplier. I used 5mm rod, and cut it into little pieces as long as required to go through to the front panel plus another mm. Sanded and polished one end, and carefully, with a vice and a bench press, and a ...

Re: Power supply

The reason your stuff blew up is that those kinds of power supplies dont output DC. Its more of a messy chopped up waveform that when averaged, looks kind of like DC. Kinda.


Your best bet is to use a phone charger wallwart, and like the other members said, saw it apart and use it directly.

Re: RGB Module

It could also be cross talk, as the signals run at a fairly high frequency.
You can try terminating both lines into 50 ohm resistors, that may help with the crosstalk and interference.

Re: NDRIVE for solenoid

You will need a protection diode, preferably at least a high current (3A) shotcky or high speed diode. The back emf of a solenoid/motor at switch off can EASILY exceed the 60 volt max rating of the N drive modules, and perhaps even drive a high voltage pulse back into the arduino itself, turning the...

Re: Ndrive driver module, PWM, FET open circuit

you can easily use the ndrive modules in a speed control circuit, i am doing this right now for computer PC fan control. PC Fans dont like direct PWM control, as they whine and can fail, so what i basically did was use the N drive module as a buck converter. I have done something similar to this cir...

Re: RGB Module

Well you could still daisy chain them and control them seperately. the other thing you can do is is use the demo code, but add a digit to each variable. so CK would be CK1 and Ck2, and then essentially redo the example twice in side the same program. A bit messier though. the RGB modules are easily ...

Re: Help needed please

You would be able to do this, however you are going to need a fair few outputs. You can either use the atmega with its more output pins, or use an eleven with a shift register module to give you more outputs. That will make the code a bit more difficult though. For the control system you could use t...

Re: Arduino versus Eleven?

the only issue i have ever had with my eleven is when i sent my pc to sleep with the eleven still plugged in. When i woke up the PC, it had hung that usb port, and i had to change ports, and then it came up with COM4 instead of COM3. Other then that no other issue. It could any number of issues affe...
