The solution to these problems isdirect port manipulation. The Atmel chip has some (3 on most Arduinos)registersfor the I/O pins, these are just bytes that store the info on whether a pin is an input or an output, whether it is set high or low, etc. Every bit of these bytes corre...
High performance - with features like zero cost global brightness scaling, high performance 8-bit math for RGB manipulation, and some of the fastest bit-bang'd SPI support around, FastLED wants to keep as many CPU cycles available for your LED patterns as possible Example This is an Arduino ...
Arduino provides four different time manipulation functions. They are −S.No.Function & Description 1 delay () function The way the delay() function works is pretty simple. It accepts a single integer (or number) argument. This number represents the time (measured in milliseconds). 2 ...

The Arduino Nano matches that requirement and is ideal for USB-programming. You could also settle less for the 33 by 18 mm dimension, an example being the Arduino Pro Mini. Power Consumption This has to do with the amount of power that the board needs to function optimally. As a rule of...
Direct port manipulation is possible as well - and in fact several powerful additional options are available for it - see direct port manipulation.PIN_Pxn - not Pxn, and not PIN_xn - those mean different things!Arduino Pin NumbersWhen a single number is used to refer to a pin - in the...
To connect my Arduino Nano to my monitor, I needed to sacrifice a VGA cable and cut it in half to expose its wires. Fortunately NUCC had a literal bucketful of them and I put one to use on this project. An electrical testing meter helped me find the right wires to use, and we wer...
On the Arduino side (controls to the Arduino) I will be using fixed length codes; “[L10]” and “[L11]”. On the AI2 side I will use comma separated data “[L,1,0]” and “[L,1,1]”. AI2 has better data manipulation functions and we can directly transfer a variable that co...
I have tested theF_AS_Toption which uses direct port access on an UNO and this is now working fine. Uncomment the line: #define F_AS_T in the "Adafruit_ILI9341_FAST.h" file when using Atmega328 (UNO/Micro Pro/Nano) processors. Put // comment in front to disable for other processor...
[647,648]Magnetic nanofluids, also called ferrofluids or smart nanofluids, has emerged as the mostly focused topic in the arena of nanofluids. The suspension of SPMNPs provides a suitable platform for the manipulation of the thermophysical and flow properties of magnetic fluids by remote ...
