The 2N7000, 2N7002, NDS7002A, 7002 is an N−channel enhancement mode field effect transistors are produced using ON semis proprietary, high cell density, DMOS technology.
The CD4001BM, HEF4001BT, and MC14001D are NOR gates provide the system designer with direct implementation of the NOR function and supplement the existing family of CMOS gates. All inputs and outputs are buffered IC SOP-14 Pins Package.
The BC856 3B is a transistors are designed for general purpose amplifier applications. They are housed in the SC−70/SOT−323 which is designed for low power surface mount applications.
The HW-040 Rotary Encoder Module is a device that generates an electrical signal based on how much the rotary input device (knob) is rotated and the direction it is rotating
