If you insist on wanting to use stripboard before testing your circuit on a solderless breadboard, here is what you need to know. As already pointed out, when you mount a DIP14 package, pin-1 is shorting to pin-14, pin-2 is shorting to pin-13, etc. You need to cut the tracks between these pairs of pins. If you are able to take advantage of this premade connection then you don't have to cut the track.




Look at the IC pinout of CD4011.


You will notice output on pin-3 is opposite input on pin-12.
Also output on pin-10 is opposite to input on pin-5.
You don't have to wire the CD4011 IC using the pins as designated in your original circuit diagram.
See if you can take advantage of the premade connections by rearranging the pin numbers of the IC.

 

This is a picture of the track side of a circuit constructed on stripboard.



You will see a row of 10 tracks that have been cut using a drill bit. (About 3mm dia.) You only drill in far enough to break the continuity of the track. These 10 track breaks are under a 20 pin DIL IC

Les.

 

For a beginner I would recommend always getting the circuit working on a breadboard then transferring onto a proto board like one of these, no cutting tracks required, and no redesigning the layout.

There are many different brands and sizes available, but the basic concept is direct transfer.

 

For a beginner, it would be wise to start with solderless breadboards.
With this you will learn how to assemble a circuit properly as well as learn how to test and debug a circuit.

Posting a layout of your circuit might be useful. Look up fritzing software.
However, when you still need someone to look over your shoulder an actual photograph is still required.

I just solder a new circuit based on the stripboard layout I've posted before but still doesn't work, maybe I there's something wrong with my stripboard layout and btw I cut the track between the IC pin

Could you kindly post the pictures on this site? Screen captures don't have sufficient detail and I'm not going to join Pinterest just to look at a picture.

 

Stripboard mistakes I see are IC pin 2 connects to two parts, R2, C2 but not in your picture. Pin 8,9,11 all together but mistake R3 in wrong spot. The circuit has R4 seemingly doing nothing but leave it.
The rain sensor to IC pin 1 is a sensitive node, so don't leave it a wide strip running near the speaker etc.

Just double check your work, or use a multimeter to beep out connections to make sure you did it right.

Does anybody else think that those transistors might be EBC and not ECB???

The spec shows 'General Purpose' and they can be ECB or EBC see BC6916 for e.g.

 

It looks like some of the cuts you made might not have opened the lines:

Measure the voltage from pin 1 to 14 on the IC. If you don't measure close to 9V, disconnect the battery and look for shorts.

Then measure the outputs. Pins 3 and 11 should be at VCC, pins 4 and 10 should be about 0V.

 

Um, what I can see is the battery clip wired wrong, the red wire is (+) and black (-) so they look backwards going to your board. If the battery was backwards... it would damage the chip, it would get hot and die. Chips don't like this at all. Unplug the battery.
I will check the strip board pics in a little while.

 

Once again, if you do not have a meter, such as even a cheap digital one that can measure voltage, there is not a whole lot of actual learning that you can achieve, except that things either work or don't work, and you are not able to understand why. The reversed battery connection is a good example of that. If you had been able to measure the voltage on the IC and found that it was reversed, it would have been a good and fast learning experience.
The soldering looks OK and so the problem is elsewhere. And I still wonder about the transistor connections Most transistors are EBC, NOT ECB. That makes quite a difference.

There are several as per #29

Yes, but some does not make it likely that the ones used are that form. And without a voltmeter the TS is not likely to be able to tell if that is the problem or not. And the backward battery connection certainly might be the problem.

I do have multimeter but it's 4am here so I might do it tomorrow and the transistor is ECB I've checked the datasheet of the transistor

 

@Hannan007_ What transistors are you using? Part No.?

OK, so the transistors are the ECB configuration. Good, because many are EBC instead. Now the next step would be to verify that the battery is connected correctly and then see if the IC is still functional. Checking that IC will not be difficult, it can be checked in place with just a voltmeter. Or the circuit might start working if the battery gets connected correctly and all the ctive devices are still OK.

I've checked the polarity using the multimeter, it shows that the black wire is positive (+) and red is negative (-)

sorry but I don't quite catch up on how to test the pins, can u tell me what what topic I should search for to test out the IC pins?
