Ratings and Reviews
Great Job!
Thank you so much for this app. I have always had to flip to the back of my Arduino book for which resistor is which now it is so much easier!👍👍👍👍👍😀😀😀😀😀
No calculations
im the dummy here i opened the app. saw all the features and upgraded to pro only to find the app perfprms no calculations you tap tap ohms law then you pointlessly check boxes like I and R fully expecting a keyboard to pop up where you enter values, but nothing happens, you hit the F(x) button and it shows all the permutations of ohms law. Wikipedia has more data nformation and provides better answers. It’s also outdated, none of the versions of PICO are in ncuded with pin outs. My recommendation would be to leave it, but if you want a pile of formulas at your fingertips, this might work for you.
Good for basics but that’s it
This app has some good calculators for resistance, capacitance, and other common things. Also has color codes for resistors and other things. Comes with a lot of good basic stuff and pin outs for raspberry pi and arduino but those pin outs are too simple. And it has a section for ICs but there are very few that are actually there in comparison to what I as a hobbyist use on the regular. Don’t buy the premium version ya it’s cheap but you don’t get much more and to me it’s not worth it.
