Differences between SPI and Arduino shiftIn SPI is fast. SPI operates only from specific pins. SPI accommodates different clock types e.g. normally high etc. SPI transmits and receives data at the same time. shiftIn is slow. shiftIn can only receive data. shiftIn can work from any digita...
We can note that the process that I’ve just showed you is probably not the best one or not professional at all, but still it does the job for getting the G-codes to work with my DIY CNC Foam Cutting Machine. Of course, for more details about this DIY CNC machine you can check my...
It’s based on the microcontroller ATmega328P which does not have USB communication built into it. Instead, it uses a secondary processor for USB-to-serial communication, which connects the microcontroller to the computer’s USB port. Arduino Leonardo The Arduino Leonardo looks like the UNO and ...
tinkerers, hobbyists, makers, and beginners. You can feed an Arduino board a set of instructions for it to carry out certain tasks. It is able to read the inputs and turn them into an output, for example, it will read a finger on a button and turn on an LED. ...
So depending on the received data, for example, if the left Joystick is moved forward, its value will be greater than 160 and in such a case will call the moveForward() custom function. If we taka a look at this function we can see that all it does is it sets the speed of the ...

A microcontroller can be programmed to do a specific task based on it’s instruction set and capabilities. Sometimes solutions are very complex, circuits also...
boards, such as Duemilanove and UNO have SPI signals routed to pins 11-13 in addition to ICSP connector, therefore shields using pins 11-13 combined with standard-sized Arduinos will interfere with SPI. INT and SS signals can be re-assigned to other pins (see below); SPI signals can not...
It writes the same thing all the time at a very fast speed, and the LED does not turn on / off. Where is the error? Can you help me, so I can make it work. Sincerely Georg Reply Sara Santos October 28, 2020 at 12:12 pm Hi. That error means that the code is crashing the...
