LCD2LPT with LIRC circuit | Next Electronics

Whoever thinks about reproducing an interface for the Aladin should first of all be aware of the fact that there are two different versions of the interface. The first version, easier to assemble, enables the user to transfer dive data...

LCD 7 digit HF counter

The resistor between basis and collector (around 47k) is to be individually set according to transistor characteristics. Without PIC in socket at the collector should be 2.5 V. The circuit described involves a transistor configuration where a resistor, typically valued at...

LCD to a PC Parallel Port

The circuit is pretty simple. The data lines on the LCD match up well with the data lines of the parallel port, and extra parallel port I/O lines can be used to simulate the RS, R/W, and E signals on...

Parallel Port Relay Interface Circuit

Below are three examples of controlling a relay from the PC's parallel printer port (LPT1 or LPT2). Figure A shows a solid-state relay controlled by one of the parallel port data lines (D0-D7) using a 300-ohm resistor and a 5-volt...

Game-scoring Display ScreenCircuit

The game-scoring display screen circuit diagram is depicted in the image above. The circuit consists of an add/subtract scoring input circuit, an add/subtract scoring circuit, a counting-decoding display circuit, and a reset circuit. The game-scoring display circuit is designed to facilitate...

direct driving LCD

The LCD in question has more pins than the microcontroller. It was not possible to expand the image for a better view. Unless there is a strong preference for using this display, it is recommended to obtain a Hitachi-compliant alphanumeric...

interfacing lcd

The EN line is referred to as 'Enable'. This control line is utilized to indicate to the LCD that data is being sent. To transmit data to the LCD, the program must ensure that this line is low (0), then...

16x2 LCD Display Custom Characters Circuit

The schematic for this tutorial is illustrated below and includes all necessary components for the tutorial to function. The PIC programming circuitry is not included, as it is assumed that the PIC is either programmed externally or that the user...

5x7 DISPLAY

You must be able to recognise components such as capacitors, diodes, zeners, transistors and resistors to build a 5x7 Display project. This information is covered in our BASIC ELECTRONICS course and a complete set of circuit symbols can be found...
