NE555 + CD4017 LED Flash DIY Kit 3-5V Light LED Module Feature: Power supply voltage: 3-5V PCB Size: 88 x 25mm This kit is not included instruction. Principle: This kit is made up main circuit and decimal counter circuit, 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. Note: This is a DIY kit, you need to assembly it. This kit is not included the instruction. Package included: 1 x NE555 + CD4017 LED Flash DIY Kit

Instructions phone calls lights: Phone calls phone calls lights kit can be used to sense the GSM signal display, sensing distance up to 1 m, is a very interesting DIY module. Electrical characteristics: Supply voltage: 3 to 12V Sensing distance: about 1 m PCB board size: 2.2cm * 2.8cm Scope: GSM mobile phone signal, for CDMA phones are useless Note: This is a DIY kit, you need to assemble it. The circuit theory: The main circuit is amplified antenna sensor signal circuit and circuit. Sensing signal through the antenna 3 to S8050 transistor amplifier to drive the LED, so that light up. When no signal is detected, no calls or no GSM phones, LED circuit is not only detects the signal to light up LED. Inductance of production: Inductance 0.25 to 0.5MM enameled available in pen core above can be around 5-10 laps. After a good round with a blade to scrape paint inductor 2, so we go soldered to the board. Package includes: 5 x DIY Kit
