FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA Description: Circuit functions: With the sound of music or other sounds, LED lights follow the rhythm of the sound (the speed of the sound) and flicker. After successful welding, you can feel the wonderful combination of sound and light. Working voltage: 3-4.5V (if you need a higher working voltage, please add a current limiting resistor on LED, usually tens of euro to 100 euro). Circuit principle: Sound-controlled LED melody lamp circuit consists of power supply circuit, microphone amplification circuit, LED luminous indicator circuit, power supply by JP input, C1 filter power supply circuit. MIC converts sound signals into electrical signals, which are coupled by C2 to Q2 amplification. The amplified signals are sent to Q1 base. Q1 drives LED to emit light. The louder the sound, the brighter the LED.

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
