The 555 timer IC is one of the most versatile chips ever produced. It was introduced by Signetics (now a part of ON Semiconductor) in 1972. It is widely used in many applications in the world of digital pulse generation. The 555 timer IC can be configured in Monostable Mode, Astable Mod...
The 555 timer IC1 in the above circuit is in the astable mode with R1=2MΩ, R2=1MΩ and C1=22µF. With this configuration, the circuit operates with atime periodof approximately 60 seconds. We are now speaking in terms of time period instead of frequency because the frequency is too...

The frequency counter uses IC 555 timer to provide clock signals at a precise time interval of one second. Arduino UNO is used as a square wave generator. AnIC 555 timerand square wave generator can be configured as anastable multivibrator. The 16×2 LCD display is used to display the freq...
In the absence of signal generator and oscilloscope, we used an organic transistor as the time-delay that controls the frequency of oscillations driven by a 555 timer IC. Characterisation required less than 200 W. In one mode of operation, 555 output displays very brief (<1 s) needle-like ...
However, this is not a problem since you can use a water level indicator circuit. You can go for a circuit with a 555 timer. It is more easy to use and also accurately indicates the water level in your tank. Unbelievable how a small device can help you save up water and time simulta...
