It actually has no direct answer. What Will Make Arduino To Read Data From Electronic Device is Common Question, like one may want to read data from a BP instrument. We Hope We Will Clarify the Basic Theory and Practical Around What to Do. Unfortunately, understanding the total thing will need understand minimum theory, performing lot of web searches, test and adapt to proceed or quit. We may need … [Read more...]

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...]

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...]

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...]

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...]

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...]

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...]

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...]

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...]
