Soon, in cities and towns around the country, thousands of Syrians were taking to the streets, chanting in solidarity with the protesters who died and detainees who'd come to be known as the "children of Daraa." Even though most of them weren't actually children, it was enough to spark a revolution.

The full-color, spiral-bound SIK guidebook (included) contains step-by-step instructions with circuit diagrams and hookup tables for building each project and circuit with the included parts. Full example code is provided, new concepts and components are explained at point of use, and troubleshooting tips offer assistance if something goes wrong.
Great beginner kit. Easy to follow online guide as well as a book included in the box yet still challenging enough to entertain my 11 year old for several hours. The kit is well packaged though it would be great to have dividers/compartments in the box for storing the parts after removing the packaging.
So, here's what I have to compare this kit to:The Make: Electronics kit, which unfortunately took a very long time to get to me, coloring my perception of their kit, plus? They didn't manage to get the book I'm SURE I ordered with the kit, to me, in addition to the shipping delay. Now, the delay wasn't their fault, they say Covid-19 shut down their warehouse.Why am I mentioning all of this?Because I'm brand new to electronics, and kits like this, except for some Radio Shack boxed kits using springs to connect circuits, and so having the BOOK is a big deal for me, because I like having the book, and yeah, yeah, I can and do go online, but this kit from Spark Fun?GREAT BOOK!And it's spiral bound, so it lays flat while I try to follow along.I like the code, and the whole thing has been working flawlessly so far: I'm halfway through the book. :)Any problems I've had have been user error, and I'm really enjoying the projects and the quality of the included components.
Sorry you are having problems with this board. To answer a few of your questions.Space, there just wasn't space, the USB circuitry on the board takes up a bit leaving us with something that had to go.We made the Pro Micro compatible with the Arduino Leonardo, that decision was made there. Keep in mind you should be able to use any pin as a SS since each device on the SPI bus needs a different SS pin.Most libraries or code actually have you assign the SS pin, it might be buried in the library. Keep in mind not all libraries work with the Leonardo/ATMega32U4 boards. If you are still having problems try emailing firstname.lastname@example.org and they should get back to you (both forums and comments are designed as user support and only loosely monitored by staff)
Hi, keep in mind these boards are very different than the Uno and so the upload process is different. You do need to make sure you have the correct board files downloaded and installed as well as the correct drivers installed (on Windows). If you still have questions feel free to email email@example.com. Also, as for the pin names, the full name is actual D0, D1, etc. as opposed to the analog pins which are A0, A1, etc. But on the Pro Micro they are shortened for space issues.
I've been helping my teenage daughter last few weeks putting together a school project for automated indoor pot plant watering, using a sparkfun soil moisture detector. Getting power consumption down as low as possible has been a challenge, but we have had reasonable success. We drive it off a small garden light solar cell and one AA rechargeable battery via a Pololu boost regulator. I took off the power LED resistor and bypass the input regulator; with the Pro Micro asleep and the boost regulator shut down it consumes very little current. (The official safe operating area at 16MHz is down to 4.5V, but I found it works fine down to 4V).A number of gotchas which took some time to figure out...1. Nearly always have to load sketches via the double reset technique to use the bootloader mode; it is a challenge to get the upload timing right since the bootloader mode only gives you an 8 second window.2. The Arduino digitalPinToInterrupt(pin) function does not map to the correct interrupt number using the pin number as printed on the silkscreen; I had to go by the sparkfun documentation instead.
I use a the Macbook Pro with OS X. Was major pain getting the drivers set up so I could download a sketch. SparkFun warns that the USB can be difficult. I almost gave up. Still cannot get Serial Port Com to operate. USB is finally working enough for my needs. But board is amazingly small and fits in my small enclosure with a OLED. Needs more debugging on the boot loader to be 100% easy to use. I would not have used the product had I known the boot loader would be so much trouble. Come on Sparkfun, put a few more debug hours in!
Sorry to hear about the issues with the pro micro. Have you contacted our technical support department @ firstname.lastname@example.org ? They might be able to help you get your setup working if you're having issues.
I am using this board strictly for a USB interface.So far it has not failed. I tried several of the cheaperboards and they either failed within a few days or didn't work at all.Time will tell with the ones from sparkfun.
I had one before and broke the USB off. This time I know to be careful and only touch it to plug in the USB cable. I had no problems getting my code loaded. I'm running a chromebook and the Arduino IDE works fine on it. When loading code, it shows up in the USB manager as a Pro Micro 5V, then the code loads and when done loading, it shows as a Leonardo. I've tried several sketches and no problems loading. Right now I am using the I2C to read data from a BNO055 with a BMP pressure sensor. My only concern is maybe I should run this sensor on 3.3V, so I'll probably be buying the 3.3V Pro Micro.
The Otto cycle is a set of processes used by spark ignition internalcombustion engines (2-stroke or 4-stroke cycles). These engines a)ingest a mixture of fuel and air, b) compress it, c) cause it toreact, thus effectively adding heat through converting chemicalenergy into thermal energy, d) expand the combustion products, andthen e) eject the combustion products and replace them with a newcharge of fuel and air. The different processes are shown inFigure 3.8:Intake stroke, gasoline vapor and air drawn into engine ().Compression stroke, , increase ().Combustion (spark), short time, essentially constant volume (). Model: heatabsorbed from a series of reservoirs at temperatures to .Power stroke: expansion ().Valve exhaust: valve opens, gas escapes.() Model: rejection of heat to series ofreservoirs at temperatures to .Exhaust stroke, piston pushes remaining combustion products out of chamber().We model the processes as all acting on a fixed mass of aircontained in a piston-cylinder arrangement, as shown inFigure 3.10.Figure 3.8:The ideal Otto cycleFigure 3.9:Sketch of an actual Otto cycleFigure 3.10:Piston and valves in a four-stroke internal combustion engineThe actual cycle does not have the sharp transitions between thedifferent processes that the ideal cycle has, and might be assketched in Figure 188.8.131.52.1 Efficiency of an ideal Otto cycleThe starting point is the general expression for the thermalefficiency of a cycle:
Figure 3.11:Ideal Otto cycle thermalefficiencyThe ideal Otto cycle efficiency is shown as a function of thecompression ratio inFigure 3.11. As thecompression ratio, , increases, increases,but so does . If is too high, the mixture will ignitewithout a spark (at the wrong location in the cycle).3.5.2 Engine work, rate of work per unit enthalpy fluxThe non-dimensional ratio of work done (the power) to the enthalpyflux through the engine is given by 2b1af7f3a8
