00:10Greetings friends, today I will present the use of the 555 integrated circuit designed to work
00:17as a general-purpose time counter and the host, the integrated circuit has demonstrated
00:22being so versatile that thousands of applications that will soon emerge were created today when
00:28This refers to any project that requires the generation of waveforms and time delays.
00:33or logic trigger devices points to the first component that comes to mind of
00:38Any designer is 555 the circuit I propose uses the well-known 555 integrated circuit and a relay
00:4912 volts and a few other components suitable for this project; we have a 100 microfarad capacitor
00:55some 1k and 10k resistors, a BC 547 transistor, and a 12-volt relay will be connected
01:03A 110-volt AC power supply for the 555 stage will go with a power supply of
01:1012 volt direct current
01:16To activate the lamps, we placed a 1k resistor and a
01:23transistor bc 547, you have to observe the relay configuration; in this case, describe which part is the
01:30normally open, normally closed, and the relay's common terminal. For this, I need to run a cable from the...
01:36Connect the transistor collector to the relay and the relay output from the other end to the positive terminal of the power supply.
01:41making sure the connection is correct since we will be working with a 110 volt power supply
01:47alter and we see throughout this video the operation that corresponds to the output of the
01:54Pin 3 of the 555 will always be in a stable state or low level, that is, on pin 3
02:01we will have
02:010 volts, for example, if in the circuit we have a 9-volt battery, the high level will be close to 9.
02:07volts and
02:08The low level will be 0 volts, which corresponds to a square wave signal, the 555 being a pulse generator or a
02:15timer
