Atx is not fabricate to use it as regulated power supply, it contain IC to contol underload or overload current, see links http://hackaday.com/2013/08/30/disabling-underover... http://planetimming.com/atx_mod/atx_mod.htmlbut you can use it, after some modification :1. connect black with green to run it.2.connect load (resistor 10W 5,0oms) in any red wire to stabilise all other outputs.
thank youfor sharing ... it will more beautiful when, you can automate it!
pinMode(pinTrig, OUTPUT);pinMode(pinEcho, INPUT); thise for configuration -----digitalWrite(pinTrig, LOW);digitalWrite(pinTrig, HIGH);digitalWrite(pinTrig, LOW);duration=pulseIn(pinEcho,HIGH);distance=(duration/2)*Vson; Serial.print(distance); Serial.println("cm");and this on for mesur distance (#define Vson 0.034 // cm/us)
