LCD Interfacing: In this tutorial i will show you how to interface 16x2 LCD with micro-controller. 16x2 means there are two rows and each row contain maximum 16 characters.  For more detail refer to the LCD datasheet, which you are using. Basic Connection: Applies 5v to pin 2 and gnd to pins 1 & 5. Use variable resistor at pin 3 to set contrast. Pins 7 to 14 are the data pins,, used to send/rec data. Pin 6 is of enable; every time when you write to lcd you should have to give high to low, to this pin. pin 4 is register select pin use to give commands like clear, home etc.   In this tutorial i will interface lcd in 4-bit instead of 8-bit, so we only required four data pins. Code: Lets write a code that will display the motor status and its direction; it will be fun!!!! Requirements: Design a motor controller circuit using l298 and display its status on lcd. LCD is connected to portb and motor controller circuit is at portd. Required two switches to change motor direction; i...

This circuit is also Very simple and easy to make , simply by using the IC and 6 other components such as resistor and capacitor, you have to run this circuit. The IC uses TDA1015T , minimum voltage require 3 volt and maximum voltage required 12 volt. Power output 0,5 Watt mono , its low power amplifier. Power amplifier Schematic below : Click image to view larger If the amplifier does not work , please check : Supply voltage Components , its damaged or not. Input connected or not Output connected or not Supply voltage of each components Line PCB.

Actually, 5.1 channel amplifier consists of 6 amplifiers 1 channel mono, which has certain specifications on each canals. Has 6 channel surround sound amplifier that consists of Front Left | Center | Front Right | Rear Left (Left Surround) | Rear Right (Right Surround) | and LFE (Subwoofer). For clarity I give a simple illustration of the layout and the circuit for these speakers. 5.1 Speaker Setup Accoustic Field Generator Acoustic Field Generator is generating acoustic sound with surround effects are adjustable with a standard Dolby Surround, able to produce surround sound is good enough but not too much need of funds. Technological developments as if not only focused on one area alone but on all fronts. The development of technologies that exist today one of them is in the field of audio. With more advanced audio technology today not only as mere entertainment but has become a hobby, hobby is not cheap of course. Many audio enthusiasts trying to make music sound t...

This simple flash you is very compact build in a brooch for example. I have the circuit extracted from a CD cover.  1.5 V LED Flash Circuit Schematic Diagram The flash uses a 1.5 V supply, this is a penlight or use a button cell. Capacitor C1 controls the flash frequency within certain limits. The declared value of C1 is the frequency about 1.3 Hz. parts List C1 = 100 uF D1 = Low current LED IC1 = LM 3909

Thanks to their high light output and long lifetimes, a white LED is an excellent choice as a replacement for the incandescent bulb in a penlight torch. However, there is a ‘but’. Depending on the current level, white LEDs need a voltage of 3 to 4 V. You thus need a penlight with at least three batteries, which is not exactly what you can call compact. Fortunately, this problem can be remedied using a simple adapter circuit.   The design described here allows a white LED to be operated from a single 1.5-V battery. It consists of a simple step-up converter and an oscillator. If the circuit is built using SMD components as much as possible, it will not be difficult to fit everything into the torch.  The actual step-up converter consists of L1 and T1. The coil is wound on an EP7 core, which consists of a spool, two core halves (T-38 core material) and a clip/screen. It is available from Farnell, among others. Wind 17 turns of 0.5-mm enamelled copper wire on the spool. If you make the wind...

Today we’re going to talk about the standard 5-way switch used in Fender Strat-style guitars—how it works, how to wire it up and variations of the switch itself. Back when Strats were first made, they came with a 3-way switch (one position for each pickup), but some savvy guitarists soon realized that if they moved the switch into a position midway between two of the “official” positions, they could get two of the pickups to turn on at the same time, resulting in new sound options.  This happened because the switch was what is known as a “make before break” switch, which means it touches the next contact before disconnecting from the previous one. It wasn’t easy to keep the switches in these in-between positions and guitarists often resorted to sticking matchsticks, etc., into the switch slot to hold them in position. Here’s how the switch looks as more of an electrical diagram. As with all images, click to enlarge. Seeing how customers were doing this, Fender eventually started in...

Amplifier circuit here is all based on the ic in the gains. Three IC TA7230P, TA7236P, TA7237AP is intregated circuit (IC) which was applied to the power amplifier. Each IC has a different output, different input voltage, all IC TA7230P, TA7236P, TA7237AP is manufactured by Toshiba. TA7230P, TA7236P, TA7237AP amplifier schematic
