Displays are always nice. So far I`ve just been demonstrating how to use 7-segmented displays to display numbers using very few resources. But what if you want to display text Or pictures Or both Well in order to do that, you`re going to need a simple LCD screen. Now there are simple led screens out there right now which work on serial communic

ation and only display text. That might be good enough for you, but I like flexibility. With a GLCD, I can use different fonts, show pictures, and even animations! What`s also really nice is that the GLCD I`m using is only $20. Granted, this is a little bit more involved to program and to get to work above the super easy Serial. print(Hello World ) commands. Heads up. There is going to be soldering. Also, to be clear, I am going to be using a Mega board. The wiring for the Uno is NOT THE SAME. But luckily, there is the wiring digram for that available in the provided manual in the GLCD library (next step). The library should automatically detect what type of board that you have. However, you can override this manually and select certain ports to act as the display pins. This may or may not be useful to you. When ever you want to update the GLCD, you can access it with GLCD. [command]. Keep in mind that this does not need to be run all the time. The display will retain the information given to it until changed. When it does update it writes over what is on top, but it does not automatically clear anything. If you write over big font with smaller font, both will bevisiblebecause the new stuff did not fully displace the old. There is a lot of examples included with the library. If you are having trouble, run glcdDiag. It will run a diagnostic on the serial monitor and it might tell you what`s wrong. Be prepared for wires....
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.....
