Water Pump Timer using Astable Multivibrator (555 IC) Circuit under 2 dollar| 555 Timer Circuit Hack

Dear Viewers, In this video, we have designed a 555-IC based water pump timer circuit to run the water pump for a specific time. The astable 555 multivibrator circuit is used for this project where a relay is used at the output of 555 to cut the power of motor starter after the end of first positive (start of negative pulse) pulse of 555 IC. The duty cycle of output pulse can be controlled easily adjusting the values of any one of R1, R2, C in the circuit applying following formulae:
t1= 0.693 × (R1+R2) × C1
t2= 0.693 × R2 × C1
