hi
im currently learning to program ardunio and for my project im using a 5v regulated power supply, and id like to turn on/off this supply to everything using a momentary push switch, been searching for circuits to do this , cant really find one can someone point me in the right direction, ie what this type of circuit is called.
thank you

 

try a latching pushbutton. push once, makes the circuit, push again, breaks the circuit. put it on the +5V going to the arduino.

 

An electronic latch switch,this type of circuit is called bistable multivibrator in electronic or in digital electronic Flip-Flop circuit.Their are many flip-flop digital IC avaliable you can use them to built an electronic latch switch.

Good Luck

 

Check these designs from the PICAXE forum (yeah, you have to register...but there's lots of general uC info there) http://www.picaxeforum.co.uk/showthread.php?20702-Latching-Circuit&p=198512#post198512 I made one that was Push-on/Push-off/or/Program-off

found what i was looking for
thank you
