In our older guides on LCD display, we have shown the initial 1602A LCD Display Arduino Connection (Blue Light White Text 16×2), added a LDR to use that display to show intensity of light. But, that way of interfacing with Arduino is too primitive and engages too many pins. It is high inconvenient for repeated use and does not give all the features. We have software serial monitor on Arduino IDE. … [Read more...]
Hardware
Detailed article on computer hardware parts like RAM, Motherboard, Processor, Graphics card. Hardware also covers topics on hardware of Server, Single Board Computers like Raspberry Pi to Libre Hardware Projects.
Arduino With DHT 11 Sensor and Arduino Online IDE : Basic IoT
Whe we hear about IoT, we think about spealized hardware. However, basic IoT is obtaining the output of sensor over the Internet from your room. Using Arduino online IDE's serial monitor is actually primitive IDE, although does not sound highly interesting or special. The temperature humidity reading on Arduino online IDE's serial monitor is actually over the internet and with 4G/LTE connection it … [Read more...]
List of Raspberry Pi Essential Accessories For The New Users
In our one old guide, we discussed in details how to setup and run Raspberry Pi from command line and list of Single Board Computers as alternative to Raspberry Pi. Unless You Are Running Raspberry Pi or Some Other Single Board Computer From Command Line, You'll Need Some Accessories. The listed things are bare minimum and one have to purchase along with Raspberry Pi or similar Single-Board … [Read more...]
Arduino DIY SD Card Reader and Cheap SD Card Reader Module
For Projects Like Arduino Door Bell We Need Some Extra Storage & Arduino DIY SD Card Reader and Cheap SD Card Reader Module Becomes Practical Matter. It is true that we can play MP3 with Arduino without SD card, but that has limitations. It may appear silly when cheap Made in China SD card readers avaible at $1.5 but actually DIY can save space or just great to test without much resource. This … [Read more...]
Cheapest Components to Learn Arduino and Other Electronic Projects
Most of the electronic projects on this website is written with the thought of limitation of budgets. Limited budget often a factor which affects learning. Here is a List of Cheapest Components to Learn Arduino and Other Electronic Projects. We guess, many readers hardly can spare $20 to $50 for learning electronics works. With Made in China recyled components and suitable guides, it is possible … [Read more...]
Smart TV Buying, Building Guide For 2018
Even 5 years back, we could easily build own high end system with a large computer monitor with HDMI input, satellite television service provider's decoding box and sound system. We actually publish such guide for building cheap, high end television to get rid of proprietary stuffs of television companies. With time, F/OSS hardware and software improved. We have Raspberry Pi and lot of Raspberry … [Read more...]
Arduino Spectrum Analyzer With MSGEQ7 IC
It is true that Arduino itself can analyse music input. But Arduino spectrum analyzer with MSGEQ7 IC makes the total thing professional grade. Problem is that, MSGEQ7 IC is not exactly cheap and for bigger displays multiple MSGEQ7 IC may be needed. Another problem of MSGEQ7 is less availability as real to use shield. In other words, most will have to buy MSGEQ7 IC as component. That is great but … [Read more...]
Tips On Using Breadboard Wire and Wire Stripper
Commonly we suggest the hobbyists and newbies to use ready to use jumper wires or build custom size jumper wires with crimp pins. Ready to use jumper wires are great but has limitations at higher end. Here are practical tips on using breadboard wire and wire stripper. Good quality jumper wires with machined pins are actually good only for breadboard. You can not use them on any kind of prototyping … [Read more...]
Multiplexing vs. Charlieplexing : Basics & Example With Arduino
In our previous article on using MAX7219 IC to build bigger display with LED, 7 segment segment LED, we talked about multiplexing. For future articles and guides on our website, it is important to know about multiplexing and charlieplexing. Multiplexing, Charlieplexing decreases pin count in a cluster of LEDs. Here is Basic Theory on Multiplexing vs. Charlieplexing & Arduino … [Read more...]
Which Smartphone is Better to Buy in 2017-2018?
Unfortunately, the question, which smartphone is better to buy in 2017-2018, has not many options. Definite reason is Nokia is actually out of game. My one decade old Nokia N73ME still is a good hardware. If you need that quality of solid hardware, then obviously it is iPhone specially if you have MacBook Pro purchased around 2012 or later. Samsung is practically clone of iPhone and good at … [Read more...]
Arduino MAX 7219 CNG Basic Circuit : LED, 7 Segment Displays
MAX 7219 and MAX 7221 quite commonly used display driver IC for LEDs. Actually the same IC was in the 8x8 LED Matrix display. Right now, we know about 7 segment LED display as electronic component and multiplexing (increasing the number of digital pins in Arduino). Here is how to create Arduino MAX 7219 CNG basic circuit to control LED, 7 Segment displays in own custom ways rather than using … [Read more...]
