Arduino Project to Product Part 3: How to Build an Arduino on a Breadboard | Digi-Key Electronics

In this video, Shawn Hymel demonstrates ways to reduce project current draw by eliminating unnecessary microcontroller support components. A bare-bones microntroller is set up on a breadboard with only the essential elements and is programmed using an Arduino Uno as an ISP (In-System Programmer) or a USB FTDI breakout board. The breadboard details and IDE configuration for each scenario are clearly explained.

Best video ever on setting things up to use a bare 328p. For those that want to dive deeper and further reduce current draw, at the expense of running slower, there are 8MHz and 1MHz bootloaders available that use the internal oscillator, instead of an external crystal. In projects like this, that spend most of their time sleeping, this can result in a much further reduced current consumption.

I enjoyed messing around with the BBC Master128 and using its USER port back in the 1980's to make LED's and relays do external things, so when the Arduino & Raspberry Pi came about I jumped at the chance to mess around as a hobby, and I love all the modules that are available. It's great there is so much help out there on the web. I really appreciate the time & effort you put into showing the memory and addressing of the chip and explaining the Boot-loader and fuses. I'm not saying I completely understand it, but it is starting to make sense. I have no problems using a serial programmer. My current goal requirements are to use the ATMega328P-PU (I shake too much these days to be messing with SMD stuff), so to take the chip, minimise the circuit it needs, put it to sleep and use the interrupts to wake it when a external condition is triggered, (a switch pushed etc). I'm also a beginner with KiCAD v5, so that's something else new. I do find hand drawn stuff copied over from hand drawings on paper using a permanent marker on single or double sided copper clad board faster for stuff I made at home a long time ago, with companies making PCBs at silly cheap prices these days it seem I can bask in the luxury of having a silkscreen, never had that before! So once it's designed and I've done a build or two at home to ensure it's perfect, soak tested it etc, then when I'm 100% happy with it I'll send away for the PCB to be professionally made up. I'm more than happy to program it in the field using a laptop, FTDI (yes, the horrible one, lol - A 16min video and they were annoyed at that, must've been a slow news day for them?). Anyway, just wanted to say thank you for a very informative video.

Keep it coming. Excellent delivery. I really wish I had found this earlier.
