Actually a cheap color display has lot of advantages over any other type displays. Monochrome graphic LCD display actually costs same. Other options of cheap display is Nokia 5110 Display (which is often reported by many users as buggy), standard 1602A LCD Display (which is an all purpose standard basic LCD display). Here is Getting Started Guide For Arduino TFT Touch Screen Shield Manufactured by … [Read more...]
Arduino Temperature & Humidity Sensor DHT 11 With LCD 1602A
Previously, we published guide on how to setup LCD 1602A with Arduino, print Arduino Temperature Humidity Sensor reading on serial display. This guide, simply combining those two guides in the same way we combined two guides on our Arduino basic light meter guide. In This Guide, We Will create a Arduino Temperature & Humidity Sensor DHT 11 With LCD 1602A Following Few Steps. A the end of this … [Read more...]
How To Convert LCD Display to LCD Serial Display For Arduino
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...]
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...]
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...]
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...]
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...]
How to Use Python on Arduino, Like to Blink LED?
We can directly use C++ on Arduino instead of using Arduino's default way. Also, we can code with C on Arduino. As readers possibly know - Arduino does not have any special language. But, How to Use Python on Arduino, For Tasks Like to Blink LED?. We need not to compile the Python scripts unlike C++ but simply run the Python scripts from Terminal/iTerm2. That is not exactly great, but kind of … [Read more...]
