Unfortunatately this only provides 1. 8v signals and still needs a converter to interface to the 3. 3v signals most raw LCD use. The main components is the TFP101A. I got mine as a free sample from TI. Also visible in this picture is the fact that only the.... -
Clip sync output to TTL level seems to take some more time to fit the extra parts on the board; as a quick fix, put a ZPD4. 7 (4. 7 V Z-Diode) between SGand ground at the POWERswitch (ring to SG) and a 1k resistor between the SGoutput from the BOTPCBand the.... -
For the wiring of the display we first of all take the ribbon cable and solder it according to the following circuit diagram on the 25 pin sub-d (parallel port) plug, whereby in my small circuit diagram I described the rear side - consequently the solder.... -
The PSoc 3 Primer kit is specifically designed to help students to master the required skills in the area of embedded systems. The kit is designed in such way that all the possible features of the microcontroller will be easily used by the students. The kit.... -
The Spartan-6 board has 2x16 LCD, indicated as in Figure. The 2x16 character LCD interface card with supports both modes 4-bit and 8-bit interface, and also facility to adjust contrast through trim pot. In 8-bit interface 11 lines needed to create 8-bit.... -
Interfacing with a HD44780 compatible display using some DIP switches and a few other components. The module that we are using is a 16 character x 2 line display that we stock over here. It uses an ST7065C controller, which is HD44780 compatible. The figure.... -
The schematic for this tutorial can be seen drawn out below. It includes everything you`d need to wire up for the tutorial to work. PIC programming circuitry is not included in the schematic as I`m assuming either you`re programming the PIC out of circuit or.... -
The schematic for this project is a modified version of the CPLD dev board schematic. There are a few new parts added for this project and you can see the completed schematic for this project below. The main parts in the schematic are the CPLD Dev Board,.... -
This PIC software combines frequency counter and frequency lock functions. By adding couple of transistors and operation amplifier TL082, it is possible to lock the LC oscillator frequency. Frequency reference is formed from the measured frequency itself.... -
This project can be used with a standard Hitachi HD44780 (or compatible) controller chip to control it through only 2 wires. There is a variety of shapes and sizes available. Line lengths of 8, 16, 20, 24, 32 and 40 characters are all standard, in one, two.... -

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
