Re: Can I make PWM with GPIO

this program will work as bad as on your pc even on a Raspi
but if you write a better program and use proper tools (for example: pigpio) you'll get good pwm output

Re: induction problem gpio relay load

Yes, you are quite right. After turning OFF the relay (GPIO from HIGH to LOW), I get massive feedback on a number of INPUT pins that are listening for momentary switches - its as if I have hit all 4 switches at once - all 4 interrupts get triggered as a result. It's not a matter of turning on or of...

i don't know if this can be useful for the specific problem, but driving inductive loads has always the problem of "feedback" in my case i'm driving a much lighter load (a simple 12V water pump), but i still have a problem. but in my case the problem is shown only when i turn off the power to the lo...

well, you can put a ina219 sensor between the power source and the pi so the pi will monitor the pi that's fun, i did it.. but you should take care of a couple of things: - since there will be a power drop, it would be better to change the resistor inside on the sensor board with a smaller one (by a...

Re: How can I access two Raspberry Pi web servers over the internet using noip.com

You can use different TCP ports and let the router forward them to the correct pi (any router should be able to do that) Or You can use different public ips (if you have and if your router manages them, not so common) Or You can set-up a reverse proxy on the router to manager different hostnames, bu...
