To do this, first, we must make the appropriate physical connections from the arduino board to the LCD. Then after, we must write the code so that whatever text we want displayed comes up on the LCD. LCDs are pretty much the standard now in order to display text to users of a device. Almost all electronic devices which give a readout to users of s

ome type of data use LCDs to do so. This includes CD players, microwaves, thermostats, ovens, all come with LCDs which display some type of readout so that users can obtain some type of data. For thermostats, it`s the temperature. For microwaves, it`s a how much time until it shuts off. For CD players, it`s what track in the CD is currently playing. LCDs are so important in electronics today that learning as much about them is a smart way to keep yourself up with the industry. So in our project, learning how to write text to LCDs is a great way to eventually learning how to build electronic devices that can display data out to an LCD so that a consumer can obtain the data he or she needs. There are plain text LCDs and graphical LCDs (GLCDs). Graphical LCDs can display fine graphical detail better than text. They are avaiable for a small price premium over text displays. We need a computer to write the code needed to send the text we want to display on the LCD to the arduino board. The arduino board then transfers this data to the LCD. We need a USB with a type A connector and a type B connector. The type A connector connects into the computer and the type B into the arduino board. Thus, we have a connection between the arduino and the computer, so that we write the code on the computer and then upload it to the arduino. For a more in-depth explanation of the pinout connections to the LCD, see HD44780 LCD Pinout. This will...
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.....
