Hello,
I am doing an automatic water dispenser system for my mini project. I have found the circuit online, but the circuit dont have the types of diode and transistor used.
I have tried to contact the owner of the circuit, but he/she has failed to respond.
I would appreciate if you can suggest what type of diode and transistor i should use to make the circuit work.
This is how it should work : http://www.youtube.com/watch?v=RPrjL4HU640
I tried using transistor TIP122 and diode 1N4001, but the motor wont stop when i removed the light from the second LDR (The lower LDR in circuit)
Thank you for reading and please help me!
