Earbuds are old fashioned earphones which snugly fit outer ear. Previously we compared headphones and earphones. In previous article, we clearly informed the readers that good headphones delivers the best sound. But for practical reasons, we do need to think about earbuds, in-ears/in-canal earphones. Many people are not sure about whether earbuds or in-ear earphones are right for them. Both has … [Read more...]
Arduino e-Paper/e-Ink Buying Guide
In the year 2012, we discussed about e-Paper. Basis of electronic paper is 1970s technology from Xerox Corporation. Since 1970s, people are saying "electronic paper will be future technology". e-Paper had the bad luck of being in competition with some other display at that time which is not exactly much costly than e-Paper. Here is Arduino e-Paper/e-Ink Buying Guide. e-Paper Still Costly, Offers … [Read more...]
Graphing With Arduino on TFT LCD Color Display : Part I
Normally we show example of real-time reading things like DHT11 on monochrome LCD displays. We can graph that information. Graphing With Arduino on TFT LCD Color Display Probably a Needed Matter to Many Users. Graphing Can Become Difficult On Display With Less Known Drivers. Previously we have talked around MCUFRIEND TFT LCD Calculator. That one had problem with working codes. There are worse … [Read more...]
Arduino Soil Moisture Sensor : How Works, What to Buy
Basic purpose of soil moisture sensors is determining percentage of water in soil, rater volumetric water content of soil mainly for watering plant. We commonly view certain type sensors in prototyping works on various websites and online stores. Basic questions which will come to mind to a newbie are - How Arduino Soil Moisture Sensor Works? What to Buy as Soil Moisture Sensor? We are trying to … [Read more...]
Arduino Flip-Flop Blinking LED With Push Button
The current series of articles we are publishing are around basics for learning Arduino and also IC. We already know that we can blink one LED with Arduino and also we can blink one LED with 555 IC. We can also blink 2 LEDs alternatively with Arduino and also blink 2 LEDs alternatively with 555 IC. From our older examples, we can start LED to be on with one pushbutton press and turn-off with … [Read more...]
Making Stereo Wireless Over Bluetooth : Proper Selection of Devices
Today, it is becoming common to see a USB pen drive like thing plugged to some power source and any type of audio system or speaker including normal earphone or headphone (we discussed how earphone and headphone differs) and audio is streamed from mobile device like Android smartphone. Such China made units cost hardly $2 per unit. Making Stereo Wireless With Bluetooth or Wi-Fi Probably One of the … [Read more...]

In recent long tour, when I connected my Samsung mobile to new … [Read more...]
Arduino Blink LED With Pushbutton Control to Turn ON and Off
We already know that we can blink one LED with Arduino and also we can blink one LED with 555 IC. We can also blink 2 LEDs alternatively with Arduino and also blink 2 LEDs alternatively with 555 IC. From our older examples, we can start LED to be on with one pushbutton press and turn-off with another pushbutton keypress. Arduino Blink LED With Pushbutton Control to Turn ON and Off is Few Steps … [Read more...]
Review of Vivo Y71 : Unique Features (Vivo’s FunTouch OS)
Probably you have read many reviews of Vivo Y71 elsewhere. But most of them are not closest to perfect. These days, "assembling" smartphones is not quite difficult. There is Android OS (which needs some payment to Google for commercial production) for just installing and selling, GPU technology of Smartphones is SoC based. Here is a Review of Vivo Y71. An Obvious Comparison Comes With Samsung J7 … [Read more...]
Dedicated Portable Audio Player Vs Smartphone For Listening Music
Sony Walkman, Phillips Cassette players were common up to the year 2000. Thereafter, Sony Walkman CD players became common. Slowly Nokia introduced Music Edition phones like Nokia N73 ME. An event in between was Apple's iPod. Many of us started to forget that dedicated music player is a different thing and started to rely on smartphones for music on the go. With recent almost vanished condition of … [Read more...]
Blink Two LEDs Alternatively With 555 IC (Classic IC Circuit Diagram II)
Commonly These Days, Many Classic Circuits We Show as Recreated on Arduino. That is Probably Good For Who Already Used With Basic Electronic Components But So For the Beginners. We Can Blink Two LEDs Alternatively With 555 IC With Simple Circuit and Minimal Basic Electronic Components. Of course, we can blink two LEDs in programmatic way with Arduino and blink one LED with 555 IC. We hope that our … [Read more...]
