byte enc1oldPins = 0; // will hold state of pins last time encoder was read byte enc2oldPins = 0; byte enc1newPins = 0; // will hold new encoder pin reading, to be compared with last time's pin states ...

Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need.

So he tried his hand with some really small SMD parts by building this USB to serial Arduino programmer. The chip he went with isn’t the FTDI part we’re used to. Instead of using an FT232RL ...

Makers, developers and Arduino enthusiasts searching for silent stepper drivers with high resolution encoders which are also Arduino compatible. May be interested in the new range of uStepper S ...

On-board jumpers allow the transmitter and receiver to be connected to a choice of Arduino I/O pins – default is Tx is connected to UART Serial pin 1 and Rx to UART Serial pin 0. The associated ...
