How can make a system which have two circuit. And one is place at ground floor and another is in roof. We send voice (like call) one from other by pushing a switch and vice versa. It may be wired system. I want to make this system. Can you please help me?

  • \$\begingroup\$ This is a vague question as there are multiple ways to approach this. Did you have a particular concept in mind? I could technically say to talk into a tin can that is tied to a string and have the receiver listen to your voice through another tin can but I'm sure you want something more technical than that. \$\endgroup\$ – KingDuken Nov 26 '18 at 16:30
  • \$\begingroup\$ This system can be wired system. Do i need to make modulator and demodulator and then through a two wire line and received at other end. How can design a practical circuit. Which will work for this 15-20ft distance. The nodes are always output but when switch is push then it take input and send to the other node. Hope it will be clear. I am waiting for your answer. \$\endgroup\$ – Tech Reboot Nov 26 '18 at 16:36
  • \$\begingroup\$ You should edit your question to show what intercom circuits you found in your research. Then ask for help if there is something you don't understand about the circuit. \$\endgroup\$ – Transistor Nov 26 '18 at 17:11

Sounds like you need something like this simple intercom. There are plenty of similar circuits about if you look. If this looks too complex, then buy something off eBay!

  • \$\begingroup\$ It is nearly something what I want. Thank you. Let me study this circuit. \$\endgroup\$ – Tech Reboot Nov 26 '18 at 17:51
