Components of the above is one component of ic which is applied as a reinforcement. Power amplifier used in an audio signal in order to become more powerful and can be heard via a tool that is the speaker. But in each set must have a voice amplifier, voltage, power quality is different. For the IC has the output power above 2 X 40 Watt with 8 Ohm output impedance. Supply voltage ranging from 18 Volt to 32 Volt.

How to build a 40 LED Bicycle Light Electronic circuit Project? This is a very Simple to build This electronic circuit project of 40 LED bicycle light.  The 555 circuit below is a flashing bicycle light powered with four C,D or AA cells (6 volts). Two sets of 20 LEDs will alternately flash at approximately 4.7 cycles per second using RC values shown (4.7K for R1, 150K for R2 and a 1uF capacitor). Time intervals for the two lamps are about 107 milliseconds (T1, upper LEDs) and 104 milliseconds (T2 lower LEDs). Two transistors are used to provide additional current beyond the 200 mA limit of the 555 timer. Simple 40 LED Bicycle Light Circuit Diagram : A single LED is placed in series with the base of the PNP transistor so that the lower 20 LEDs turn off when the 555 output goes high during the T1 time interval. The high output level of the 555 timer is 1.7 volts less than the supply voltage. Adding the LED increases the forward voltage required for the PNP transistor to about 2.7 vo...
