Use the Ethernet Library to write sketches which connect to the internet using the shield
so that only one wire (and ground) needs to be connected from a central microprocessor
The TC output is normally LOW and goes HIGH when a circuit reaches zero in the count-downmode or reaches '15' in the count-up-mode
74HC157 (Quad 2-input Multiplexer) load cell 1 kg 16 have Blue filtersIntroduction : 74HC157 (Quad 2 input Multiplexer). 74HC1457 is a quad 2 input multiplexer. The device features select (S) and enable E inputs. A HIGH on S selects data source 1, a LOW data source 0. A HIGH on E forces all the outputs (1Y to 4Y) LOW. Inputs include clamp diodes . This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Features ; Supply voltage : 2 6 v. Low input current : 1 mA. Temperture
