When you Upload code to esp01 you must connect TX(ESP), TX( ARDUINO) and RX RX ...because serial communication is from IDE (USB) to ESP ; but when you want to establish communication between ESP and ARDUINO you should connect RX TX ;TXRX
thank you for sharing, you have making the best project for me ..you're actually a professional engineer.!
thank you... easy and helpfull for beginner
Thank you for sharing. Nice , good job.
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)
