what is 555 Timer IC?
The 555 timer IC is a very popular timer IC and it is widely used in many timing related applications.
It can be used as an oscillator, LED Flasher, tone generator, Frequency division, and timing delay generation.
The 555 timer IC is available in many packages but most popular is 8 pin DIP (Dual Inline Package).
The following is the list of the individual pin of 555 timer IC.
1. Ground
2. Trigger
3. Output
4. Reset
5. Control
6. Threshold
7. Discharge
8. Vcc
In this video, the brief description of each pin is given.
If you see the internal block diagram of 555 timer IC then it consists of the following parts.
1. Voltage Divider Circuit
2. Comparator
3. SR Flip-Flop
4. Discharge Circuit
5. Output Driver Circuit
In this video, the function of each block is explained in detail.
By connecting the external resistors and capacitor to the different pin of this 555 timer IC, it can be configured as either Astable, Monostable or Bistable Multivibrator and can be used in wide range of timing related applications.
This video will be helpful to all the students of science and engineering in understanding the basic working of 555 timer IC.

@ALLABOUTELECTRONICS 5 жыл бұрын

If you observe, at the inverting node, two resistors (R+R) are connected in series. So, the voltage at the inverting node would be (R+R)*V / (2R +R) = 2/3 Vcc.

How 2R is written in potential divider formula on 1st comparator

@ALLABOUTELECTRONICS 2 жыл бұрын

There are three resistors. And comparators are assumed to be ideal. So, using the voltage divider, the voltage across the node is found. See, the voltage at that node is the voltage across the two resistors. If the current flowing the resistors is I, then voltage at that node is I * 2R. And current I is Vcc / (R + R + R). That means voltage at that node is 2R* Vcc / 3R = 2/3 Vcc. I hope, it will clear your doubt.

@ALLABOUTELECTRONICS 4 жыл бұрын

You can use 555 timer as monostable multivibrator. The sensor output will act act as a trigger for monostable. You can select the RC time constant to get 10s of time. Similarly you can also generate the trigger signal corresponding to push button and can give it to another monostable. At the output of the monostable, you can connect the solenoid. I hope it will help you.

@@tnamen1307 If you look at the internal digram, the 2/3Vcc is provided to the comparator using voltage divider right !! And the control pin is directly connected to the inverting terminal of the comparator. Or just after the first resistor. So, whatever voltage is applied at the control pin, the same voltage will appear as a reference for the comparator. Again here 2/3Vcc voltage is applied using a voltage divider, so KVL will not get violated even if we apply the control voltage to the same node. (As there is a resistor between the Vcc and control pin). It would have been violated if the 2/3Vcc voltage is directly applied to the comparator from the supply (instead of using a voltage divider) I hope it will clear your doubt.
