time attendance systems

74HC147 9-input priority encoders accept data from nine active LOW inputs (l1 to l9) and provide binary representation on the four active LOW inputs (Y0 to Y3)

The split core type is suitable for DIY use it can be clipped straight on to either the live or neutral wire coming into the building without having to do any high voltage electrical work

Maximum current allowed to draw through each gate output: 25mA

Potentiometer (50 KOHM) Temperature Sensor time attendance systemsIntroduction: Resistors are the most fundamental and commonly used of all the electronic components, to the point where they are almost taken for granted but they play a vital role within a circuit. The principal job of a resistor within an electrical or electronic circuit is to resist , regulate or to set the flow of electrons (current) through them by using the type of conductive material from which they are composed. Resistors can also be connected
