A quick introduction, I'm retired Master Auto Tech 65 yr.'s old and just stumbled intro Arduino. Always been interested in electrical & mechanical things. any way I saw this guy Dave at ( EEVBlog ) explaining OP-Amps and I was blown away I bought an analog and digital scope an assortment of electrical parts and an Arduino UNO, bread boards, and an assortment of sensors and things to play with. Enough, The reason I asked you here is. I bought 2 Transistor checkers ( http://www.instructables.com/id/... )
I did nothing but light up the display the 2nd worked I swapped out the atmel chip and it worked so I thought I would re program it I bought a ARV programmer ( http://www.jyetech.com/Products/... ) It says to Change the board into USB-UART converter
The board can be easily changed into an USB-UART converter by following steps below.
1. Add the resistor R8 (simply short it if you don’t have a 0 ohm resistor handy)
2. Flash the MCU with AVR-CDC firmware (available at http://www.recursion.jp/avrcdc/ or
www.jyetech.com ). when I plug it programmer into my PC Windows 10 it does not see it, it sees the Arduino I tried a couple of avrcdc files but nothing I'm wondering if I need to remove the resistor first at this point I'm lost!
I almost didn't post this, I read the tutorial about posting on this site and it sounds like I was being made to feel inferior to the GODS.
Look I'm old and tired, all of this has happened inn the last 2 months and I have been doing nothing but reading for days at a time. if someone could help my or point me in the right direction I would be grateful.
understanding op-amps, Mosfet, diodes, voltage dividers, and trying not to be confused over weather at the moment it's flowing from + to - or need to relies it's - to + I'm looking at.
I'M TIRED thanks for the time. Mick
