I am using Arduino Uno. I want to control my room lamp both manually and over the network, so when I switch off my lamp manually, how do I get acknowledgement over the network that lamp is off ?

  • Disconnect the switch from the lamp and instead connect it to a digital pin on the Arduino. Have the Arduino toggle the lamp when the switch changes position. Commented Aug 20, 2016 at 20:03
  • Or attach a lightsensor to see if the bulb is on. Commented Aug 20, 2016 at 20:04

  • Please read How do I ask a good question?. What do you mean by "manually"? What do you mean by "acknowledgement over the network"? I don't know why the above comments have been reported to the moderators. Commented Aug 21, 2016 at 9:09
