Also don't forget that I2C requires that both the clock and the data lines be pulled up to +5Volts (with 4.7K resistors each) hj

@triform Thank you for your response. I recently bought Kester solder from Amazon. It is quite good.

I also like buying from Tayda. Their delivery is accurate and prompt. I like that they provide datasheet access to the components they offer (transist...

Looks very nice. I hope it will not be too tight for all the wiring. hj

The STM32 looks very promising. I intend to try it out in the near future. hj

Unless you need high speed or heavy calculations, Arduinos provide very good performance. I like them very much, especially the micro pro 3.3 or 5 vol...

Nice one. Thanks for sharing this. It certainly makes things a bit clearer. hj

Thanks for a great article and very informative write up. I learned a lot from it and hope to be able to implement your ideas in my future projects. h...

Thank you for your response. I shall purchase one. (searching for the lowest price...) ?

Glad to have helped.

I would like to learn from your experience with this scope, as I am considering purchasing one for myself. hj

Thank you for sharing this. It is very interesting and instructive. hj

It all depends on how accurate you need your instruments to be. For the needs of us; hobbyists, makers and tinkerers, even low priced instruments ar...
