we know that people do not pour the water on to the plants in their gardens when they go to vacation or often forget to water plants. hex inverter 7404: the main function of the inverter is to give the complemented output for its input i.e. for example, if the input is low to the inverter, then the output will be high. 7404 ic will be having six independent inverters; operating supply voltage is around 4.75v minimum to 5.5v maximum, normal supply voltage is 5v. the pin configuration of hex inverter 7404 is shown below. in the circuit, there is 240ac connected to the pin no 5 of the relay,what is the function of that 240 ac?
and can you please explain the connection of relay part plzz rpl as soon as possible…. how can we keep the first 555 timer i.e it is in monostable mode output constant .here why u apply the first timer output to second timer output. the reason behind using ic555 has not been understood..here ic 555 has been used as invertor gate .so any inverter gate can be used in place of ic555.can anyone endorse/correct? please tell me wheather there is any comnection between the capacitor and the first 555 timer at the output terminal of the first 555 timer in the circuit. can anyone please explain me of usage of two 555 timers..isnt one 555 timer in astable mode sufficient for thus operation?? thanks hello, can i get a video of automatic plant irrigation system using two 555 timers? as i am using this for my project .. i need you to help me .. i request you.. i would get the output with your help .. hope you reply soon thank you.
