Hello Everyone!

Hope you are all doing well. I’m excited to announce that this month's AskE14 question is: What is the worst mistake or problem you've encountered during a project, and what did you learn from it?

Sharing your experiences can help others identify similar challenges and understand how to overcome them. I hope this discussion will be beneficial for those who are just starting out on a project or feeling stuck with a problem.

Here's the question:

What’s the worst mistake/problem you’ve made during a project, and what did you learn from it?

    I connected LM7805 in series with LM1117 3.3v. microcontroller powered by 3.3v started working improperly and was getting reset again and again.

    What did I learn?

    Never cascade LM7805 with LM1117 3.3v for running integrated circuits and microcontroller use other solution instead.

    that is interesting - in theory, LM1117 dropout voltage of max. 1.3V should allow it to operate connected to the 5V power supply. Did you manage to find the cause of the problems? maybe more bypass capacitors were required?
