INTERCOM
Steren’s Team.
-3.-Hello everyone!, This is the Steren’s Team, and today we are going to make an intercom.
-2.-Let’s begin here, we areshowing our material for the practice and the diagram to do it.
LETS BIGUIN HIR, WI AR SHOWING AUR MATERIAL FOR THE PRACTIZ AND THE DAIAGRAM TU DU ET
-1.-once youidentify it you can begin,
1.-Let's start placing our Integrated 741 and connecting it to 9v.
2.-Then, following the diagram, place a wire for a bridgeresistance 1Kohm to ground.
3.-Then place a wire from PIN 2 of the 741 to a 1 Kohm resistance to the first input of a 100k potentiometer, and another wire fromthe PIN 1 to the PIN 2, and the third to the PIN 6 of 741.
4.-On the other hand, we welded the speakers (Felix)
ON DE ODER JAND, WI WELD D DE SPIKERS
5.-Iam cutting some wires to make connections. (Rosales)
6.-Returning to our practice, I will place a resistor from the PIN 3 of the 741 to ground.
7.-Then,we'll place a wire from the PIN 6 of 741 into the first PIN of a 100k potentiometer
8.-The second PIN will be connected to the PIN 3 of the integrated 386, andthe third should be connected to ground.
9.-We have already placed the 386; now we will put the wires to feed it (386)
10.-I'm making sure everything isproperly connected.
11.-Then proceed to set the switch double pole double throw or "DPDT"
12.-And, Finally you can put the speakers.
13.-Here is ourpractice finished, just need to check it out. For this we will need two people, one for each speaker to ensure that send and receive voice.
14.-See the result.
