NE555 CD4017 LCD Light Water suite DIY Kits Electronic Module ICSK057A Red
Item 1 Item Description:
Kit Model: LSD-10
Supply Voltage :3 - 4 .5 V
PCB size: 88 * 25mm
PCB thickness: 1.0mmCircuit:
The kit mainly by the clock generation circuit and decimal counter circuit constitute
By NE555 core self-excited multivibrator power through R2, R1, VR1 to charge the capacitor C2, when C2 just start charging, U1's pin 2 is low, so the output end of the 3 foot was high power by R2, R1, VR1 C2 charges to 2/3 of the supply voltage, the output level of 3 feet from high to low, U1 internal discharge tube is turned on, capacitor C2 via VR1, R1, U1 pin 7 discharge , less than 1/3 of the supply voltage until the voltage across C2, U1's level of 3 feet from the low to high level. C1 again charging, so the cycle formed oscillation. The charging time is: 0.695 (R2 R1 VR1) C2 discharge time: 0.695 (VR1 R1) C2, regulator VR1 can be controlled oscillator output frequency, U1 clock oscillation signal constantly applied to the U2 to pin 14, U2's 10 output terminal 10 is connected with LED, when U2's 10 output terminal to produce a high level in the clock signal under the action of rotation, D1 - D10 are sequentially lit, thereby forming a flowing light effect.Adjust VR1 to adjust the flow rate of the LED lights. Package Included: 1 x NE555 CD4017 LED Light Water DIY Kit Electronic Suite Lamp Module Red
Item 2
Electronic dice kit is based on the NE555 oscillator circuit and fun circuit CD4017 counter display kit. Can simulate the dice, make fun of the game. 1. Kit parameters:
Supply voltage: 4.5-5V
Dimensions: 74 * 35mm 2. Function play:
When a power-up, 7 LED will randomly display a number of points, players press the switch S1,7 all lit LED only after about 7 seconds LED light starts blinking, until finally showed stable points. Throughout the end of the first "crap" process.
3.Circuit: circuit mainly by the pulse generator and a decade counter circuit. Pulse generator and external elements by NE555 multivibrator, when you press the button S1 when Q1 turns on, the output pulse NE555 3 feet, then five turns the output CD4017 output high, resistors and transistors by different combination, can drive seven LED light to indicate the number of points 1-6 points
Item 3Description: Board size. 53mm*19mm Supply Voltage :2.5 - 14 .5 V This package is mainly decimal counter circuit and circuit generated by the clock , from the core of the self-excited NE555 multivibrator power through R2, R3, R4 charge the capacitor C1, C1 started when charging , NE555 2 feet still in low, so the output pin 3 goes high when power through R2, R3, R4 to charge C1 to 2/3 of the supply voltage , the output pin 3 level from high to low , NE555 conducting internal discharge , capacitor C1 through R4, R3, NE555 7 feet discharge until the voltage across C1 is less than 1 /3 of the supply voltage , NE555 and 3 feet level from low to high . C1 and charge again this cycle oscillations formed . Charging time : 0.695 (R2 R3 R4) C1, discharge time : 0.695 (R4 R3) C1, R4 can be adjusted to control the output frequency of the oscillator , the oscillation clock signal is applied continuously NE555 CD4017 14 feet , the output terminal 10 is connected with the CD4017 10 LED, when the output terminal 10 turns CD4017 generated clock signal is applied at a high level , the D1 - D10 are sequentially lit to form a water -light effect .You can adjust the flow rate adjustment R4 LED lights . Package included: 1* NE555 CD4017 Flow LED Light Electronic Production Suite
