I would like to do an ON OFF *switch* for the B+.
Is that possible?
Is it enough to connect the switch to 2 pins on the GPIO ? If so, what are the pins to connect?
Or do I need some other circuitry? If so, may i retrieve the scheme online?

the case you linked is form fitting, there is no way to fit a switch inside it without having micro usb extension cables looping around from outside to in.RepublicanSwag wrote:Will this slick-looking power switch http://mausberry-circuits.myshopify.com ... own-switch fit within this case https://www.modmypi.com/blog/introducin ... berry-pi-b ?
Also, does this switch cover all of the USB ports?
And would this work with the B+ model?
It is not a good idea to run anything noisy like a DC motor from any pin of the Pi. First the Pi pins cannot support the load requirements of a motor. 2nd the electrical noise imposed on the clean power rail of the Pi is certainly disastrous. Always drive loads with current bearing devices like a driver board, a Darlington transistor array of even a simple transistor circuit. There are millions of examples of this on the net. Furthermore motors will create back currents from the rapid collapsing of the windings as the armature spins. These backward currents can easily exceed the voltage you apply to the motor and will certainly exceed the ratings of a fragile device like the Pi. I hate to say it but I think you are going to need to get a new Pi.karthik sriram wrote:Hi,I am karthik pursuing my BE 3rd year. I bought a new raspberry pi 2 model B with 1 GB ram.
I connected it to my pc with rasbian OS.Its was working well,but when i connected a small dc motor to its i/o pin 5v and gnd,the motor \was running .suddendly the red and green led switched off and now i cant able to on my raspberry pi,when i connect my micro usb to power supply it,there is no response from it.no red n green light blinking.but when i disconnect the supply,the green led blinks once.can anyone help me please.
