Digital Step Counter By Rakhi280

Digital Step-Km Counter Max. range: 9,950 meters with dickens digits Slip it in pants goop for walking and jogging Circuit plot: Parts: R1,R3____22K 1/4W Resistor R2________2M2 1/4W Resistor R4________1M 1/4W Resistor R5,R7,R8__4K7 1/4W Resistor R6_______47R 1/4W Resistor R9________1K 1/4W Resistor C1_______47nF 63V Polyester Capacitor C2______ one hundrednF 63V Polyester Capacitor C3_______10nF 63V Polyester Capacitor C4_______10µF 25V electrolytic condenser Capacitor D1_______Common-cathode 7-segment direct mini- parade (Hundreds meters) D2_______Common-cathode 7-segment LED mini- video display (Kilometers) IC1______4093 Quad 2 input Schmitt NAND gate IC IC2______4024 7 stage ripple calculateerpunch IC IC3,IC4__4026 Decade counter with decoded 7-segment display outputs IC Q1,Q2___BC327 45V 800mA PNP Transistors P1_______SPST Pushbutton (Reset) P2_______SPST Pushbutton (Display) SW1______SPST Mercury riff, called also coggle Switch SW2______SPST slipper Switch (Sound on-off) SW3______SPST Slider Switch (Power on-off) BZ_______Piezo sounder B1_______3V onslaught (2 AA 1.5V Cells in series) catch train: This circuit measures the distance cover during a walk.

ironware is fit(p) in a tenuous box slipped in pants bag and the display is conceived in the future(a) manner: the left display D2 (the most significant digit) shows 0 to 9 Km. and its disperse is ever on to separate Km. from hm. The rightmost display D1 (the to the lowest detail significant digit) shows hundreds meters and its dot illuminates after every 50 meters of walking. A beeper (excludable), signals each count unit, occurring every two steps. A normal step was figure to span around 78 centimeters, thus the LED foretoken 50 meters illuminates after 64 steps (or 32 operations of the mercury switch), the display indicates hundred meters after 128 steps and so on. For low battery economic consumption the display illuminates single on request, pushing on P2. accidental reset of the...If you urgency to get a ripe essay, order of magnitude it on our website: Orderessay
