@fhaddad Any update on this? Interested I your findings/resolution.

@fhaddad First a few questions... 1. Is the following correct? You've implemented your circuit on a PCB and it does not appear to supply enough curren...

Thanks @frogandtoad , I'm not certain that I, entirely, grasp what you've posted. However, I'll try a few things out and see what there is to see. As...

@frogandtoad Great. While I've got my code running, I would like to know why, and/or if there are better ways to achieve it.

The design goal was to use an Arduino to move something around. Success :) My current design uses three Arduinos, a Raspberry Pi, and a couple of AT...

@angelob When I retired, I wanted to get a leg up on Python programming. I found lots of YouTube videos, but did not find any that I'd consider profes...

My first is built and gone :) Well, mostly a bump and go really :( Made huge progress on the code for my second this week, but still have a long way ...

I like a mosfet because it has a lower resistance (drain to source) and therefore consumes less power (generatws less heat). They can be a smidge tric...

OK. So, as blind leading the blind we have... #ifndef Wire_h#include <Wire.h>#endifDoes not work. It throws... In file included from U:\New Sket...

@pugwash That is an odd one. I originally put those three lines in to resolve a problem. While it (at the time) seemed to resolve the problem, when I ...

Many thanks @frogandtoad All feed back is welcome. Just one question... Regarding passing the object by reference, does this require that there is a S...

Hey @pugwash. You've inspired me to give the problem a try. Also, I wanted to try to implement instructions for building an Arduino library, that Ral...

Looks fine. I'd have gone with a lighter gate resistor (maybe 4.7k or 10k), but 1.0k shouldn't give you any grief. Keep an eye on the heat sink of the...

IRF540 looks like a good candidate. More then powerful enough and the max Vgs(th) is 4 volts. As long as you drive the ATting85 on 5 volts, you should...

This may work... I have used a Pololu Buck/Boost converter in in the past (PN-S9V11MA). It has an enable pin. The converter can be turned on and off v...
