Protecting components when AVR malfunctions
I watched a Youtube of a guy using just a single LED but he used a lens and tube with the sensor in the center basically a monocular telescope. I bought one on Amazon for $18.00...

Protecting components when AVR malfunctions
Fantastic information , I very much appreciate. I have had some major back pain and have not been able to sit and putter with this project but today I muscled through it and...

Photo Transistor Operating Modes
It did work though using a 100k resistor in reverse but not very well. Don't you hat it when things kind of work instead of having a binary result.

Photo Transistor Operating Modes
Well I am embarrassed now, Turns out when I soldered in the IR Photo Transistor I put it in backwards. now Avrcandies was spot on my circuit setup was JUNK! Thanks to all the...

Photo Transistor Operating Modes
With 10K I get 5V and 4.37V difference in voltage with emitter on and off.  Emitter is using 5V with a 20 ohm resistor drawing 190ma so it seems the emitter would need to be...

avr-gcc Code Syntax/Libraries vs CodeVision Code Syntax/Libraries
My intention is not to convert code between compilers.  My edit in the initial post this morning I did find where I did not include avr/interrupt.h The comparison...

Ha, after setting up my second computer out in my garage where I have my CnC mills and installing Studio7 I thought I would just go off the data sheet and try a program without...

Very old AVR Dragon found while cleaning up my old box of microcontroller stuff
I was searching for a tiny11 programmer (because i have quite a few 11's and 12's I found last night. And what did I find? I wonder if I was correct in this post, I will have to...

Very old AVR Dragon found while cleaning up my old box of microcontroller stuff
Hmmm I am thinking perhaps I only used it for HV Programming here is a picture of the wires I soldered what 20 years ago or something   Is there a datasheet for this model...
