74HC47 ( BCD to 7-Segment Decoder) 74HC08 in this example the Priamry

in this example the Priamry power will be provided by the Arduino

The 74HC Family use silicon gate CMOS technology to achieve operating speeds similar to the LSTTL family but with the low power consumption of standard CMOS integrated circuits

It can easily transfer data wirelessly

which would be more precisely

of Pins : 4Pins

74HC47 ( BCD to 7-Segment Decoder) 74HC08 in this example the PriamryIntroduction : 74HC47 is a BCD to 7 segment latch decoder driver with four address inputs (A, B, C, D), a latch enable input (LE), a ripple blanking input (BI), a lamp test input (LT), and seven segment outputs (a to g). When LE is LOW, the state of the segment outputs (a to g) is determined by the data on A to D. When LE goes HIGH, the last data present on A to D are stored in the latches and the segment outputs remain stable. When LT is LOW, all the
