It is a simple full adder one that everybody makes simple design with one xor gate , one and , one or gate. I don’t have the sketch at this moment but will try to provide oneHi Humor,
Welcome to AAC.
Do you have a sketch of the circuit you could post.?

Thanks for the information will surely try.Just for the learning experience, if you can put it back on your battery and attach a scope then you will be able to see the voltage drop on the scope if that was the problem. If the battery is at 5V, set the trigger point as falling edge around 4.5V, put the scope in normal mode then turn the circuit on and watch. If you have a storage scope (digital) set it to record multiple frames, because if you have multiple dips they may go by so fast that you only see the last dip, and it might not be the worst dip. If you set it to record frames then it will record basically a screen shot every time it triggers. If you don't have a storage scope, then just keep moving your trigger point lower until it doesn't trigger anymore, then you'll know what the lowest dip is.
One more side note; those phone chargers are often not regulated very well and the voltage can get really high when there's little or no load. Measure its output with no load attached and compare that against the "absolute maximum ratings" in the data sheets for each of the parts you're using. If the voltage is higher than the absolute max for any of your parts, then you can add a zener diode between your V+ input and ground and that will spare your parts from being cooked by over voltage. This is not always ideal as a big power supply can just smoke the diode, but for a learning project with a small power supply, a sufficiently large zener is likely fine.
You need help to use Google?Can anybody provide the data sheet of a 74ls48 ic
