Also we will controlled robotic hand using with nRF24L01. This video shows the low-cost “robotic hand” construction. You can get excellent results with better flex sensors and servo motors.

But everything else — clock, memory, and power — are from an Arduino Mega 2560. You could argue that’s two chips, but the board actually has several chips on it.

The hands are actually the Raptor-Reloaded open source 3D-printed prosthetic hands, although XenonJohn has modified them by adding coils of wire that function as magnets for each of the fingertips.

He has the processor, of course. But everything else — clock, memory, and power — are from an Arduino Mega 2560. You could argue that’s two chips, but the board actually has several chips on it.

An inspiring Arduino project created by Sang-won Leigh has been unveiled that takes the form of an Arduino wearable device that adds an extra robotic hand to your wrist. This innovative device can ...

Meanwhile, the Arduino Mega is getting the same USB chip along with an ATMega2560 processor with twice the memory. Right now only 128K is available, but that's a software limitation and they're ...
