Part of the problem with getting advice on this is that people operate at very different scales when it comes to electronic component selections. Pe...

If you are just looking for the basic voltage/amperage check, you can do a DIY option as well. I doubt it saves you much in terms of money (on sale, t...

DC SSRs exist, but they are distinct devices. If you want to switch DC with an SSR, you need to buy a "DC to DC SSR". Yes, those relay modules sho...

I use exactly that oscilloscope (DSO138) for exactly the purposes you have described (debugging 555 PWM timers). One reason for simply buying the kit ...

[I am somewhat confused... I was certain I answered this thread earlier, but I can't see my reply anywhere. I wonder if I wrote it up and forgot to ac...

While the atmega328 is a fairly easy chip to design a PCB for, you do need to make plans for programming it via serial ahead of time. However... for...

For the 74LS83, I wonder if most people just switched to the 74HC283.

One simpler solution is just not to use LS gates if you're working with ~3V logic. The 74HC CMOS series of gates can run anywhere in the 2V-6V range f...

Hi @ronalex4203, Unfortunately I'm not quite sure what you're asking. Mechanically you can usually hang small daughter-boards like this off your m...

If you can get away with it, when salvaging a component that has been hotglued... acetone works pretty well. You do have to be a bit careful when salv...

The problem is that as soon as you enter the SOS state, you're only looking at the button pin every ~6 seconds. There's no code to check the buttonPin...

Are we mainly talking about electronic components? To some extent it depends on what type of projects you want to do. Collecting a basic set of comp...

My recomendation would be to look at the smallest time unit you care about... which seems to be 100ms. And rework the code around only updating every ...

The TB6612 (or any other h-bridge) is certainly not the easiest way to use stepper motors. A single TB6612 can control exactly one stepper motor, and ...

A few years ago, my office threw away an old version of one of these:/p> I salvaged it from the trash and took it home. I don't use it often, but wh...
