May be, reading the Part 2 of Arduino TFT Touch Screen matter will help you. The touch screen shield I got has ST7789V (0x7789), which is somewhat uncommon. This article is Part 2 of Arduino TFT Touch Screen Calculator By MCUFRIEND. These cheap China used-display stuffs basically have some risk of purchasing. If the driver is rare, you do not have much options. Identifying driver not also that … [Read more...]
What is Thermistor : Basics on Thermistor Using Arduino Project
In 1833, Michael Faraday discovered the first NTC thermistor. In high school, you were taught metal couple get bent with temperature. That thing is more old. Here is Basic Theory and Practical Basic Example on Thermistor Using Arduino Project With Circuit Diagram and Code. What is Thermistor? Thermistor is a basic electronic component like LDR, it is also a type of resistor whose resistance is … [Read more...]
Neon Lamp (Power Indicator) and Nixie Tube
Even if you saw Neon Lamp, unless you know you just think as incandescent bulb. If you see the photograph, you'll immediately identify the thing inside your house like in some plugs. They are NE-2 Neo Lamps, lighting since 1838. They were co-invented by Sir William Ramsay, who discovered Nobel gas too. The other inventor was Morris Travers. Morris Travers established Indian Institute of Science … [Read more...]
What is UART in Plain English?
We often face the phrase universal asynchronous receiver-transmitter in matters like serial communication of Arduino or some shield's of Arduino. What is UART in Plain English? UART is an electronic circuit used to implement digital serial interfaces of computer or peripheral devices. Serial transmission is commonly used for modems, non-networked communication between computers or peripherals. … [Read more...]
Cheap, Small Arduino Projects With ATtiny 13, ATtiny 10 (Basics)
For the past few years, Atmel manufacturing smaller microcontrollers. ATtiny 85 is quite known. You Can Create Cheap, Small Arduino Projects With ATtiny 13, ATtiny 10. They cost $1 or lesser per unit and needs no external components. Basic problem is that - you probably can not get ATtiny13 or lower in local shop. So, ordering one unit not going to worth the amount of work. Among ATtiny 13 and … [Read more...]
Is Learning 8051 Microcontroller Needed Despite Having Arduino?
8051 is an older microcontroller than Atmega (which Arduino boards commonly use). 8051 has developmental board or one can build from basic electronic components. Now, after a certain point of learning, one may ask - Is Learning 8051 Microcontroller Needed Despite Having Arduino? Sadly, there is no easy answer. We talked about Von Neumann Architecture, ARM architecture etc. Good engineer, good … [Read more...]
Graphical LCD (GLCD) Buying Guide For Arduino
Previously, we published how to interface and run 1602A blue backlight 16x2 LCD and also some projects with that display. Graphical LCD Actually Practical Over 16x2 LCDs. There is 20x4 LCDs as well (which has difference). Here is Graphical LCD (GLCD) Buying Guide For Arduino as There Are Matters to Know Like Controllers. 1602A 16x2 LCD actually easier as it is far more basic electronic component … [Read more...]
What is Logic Analyzer? What is Use of Logic Analyzer?
There are quite frequently asked questions like - What is Logic Analyzer? What is Use of Logic Analyzer? Is it a necessary equipment for a leaner of electronics? Possibly for answering them, we need to know basic about Logic Analyzer. What is Logic Analyzer? A logic analyzer is a testing instrument which captures the data of a digital circuit and displays it for analysis, … [Read more...]
Turn On LED On Dark Without Arduino Program
In our previous guide to Create an Arduino LDR Module With Transistor, at the end of the guide we discussed about lighting up LED without microcontroller with minimum modification of that circuit. Not all the readers are enough advanced to modify circuit own self to make the current thing. We Can Use NPN Transistor, Resistors to Turn On LED On Dark Without Need of Arduino Program. That is Great … [Read more...]
Create an Arduino LDR Module With Transistor
In our previously published guides, we listed commonly used transistors with Arduino and How to Turn on LED with LDR. In that turning LED on, we needed no transistor. We Can Create an Arduino LDR Module With Transistor in Easy Way to Print Response as Either Zero or One. We will use a BC 547 as transistor, which is an NPN transistor. After testing this diagram on breadboard, you can make it … [Read more...]
Arduino Stepper Motor Buying Guide (Driver IC Included)
Stepper Motor is Much More Complicated From Buying Point of View Than Servo Motor. If you are new with electronics, we will suggest you to first work with 3V DC Motor, then try Servo Motor and after mastering basic sensors, ICs which are commonly used with Arduino; think for stepper motor. In Other Words, In This Arduino Stepper Motor Buying Guide, We Are Taking it Granted That You Know Needed … [Read more...]
