Some theory better to know before buying rotary encoders. Here is rotary encoder for dummies guide intended for Arduino, Raspberry Pi users. Rotary encoders are like potentiometers but potentiometers do not have full rotation without limits unlike encoders. Rotary encoders output reflected binary code (RBC) (also known as Gray code) to inform how much, in which direction the encoder has been … [Read more...]
Arduino 8 Digit 7 Segment LED Display Buying Guide
Unlike TM1637 4 digit 7 Segment LED Display, buying 8 digit 7 segment LED display is not so easy to take decision. These Are Driven By MAX7219/MAX7221 driver which supports LED dot matrix too. 8 digit is maximum number the driver supports. It is towards pure electronics, you can separately buy the basic electronic components and build on breadboard. Arduino has direct official support of the … [Read more...]
Arduino Multifunction Shield (HCARDU0085) : Features
This is kind of review out of marketing research as ex-willing consumer. Initially I thought that it is Made in China and has lot of sensors. Arduino Multifunction Shield has 4 digit 7 segment led display, 4 SMD led, 10k potentiometer, 3 push buttons, buzzer and lot of interfaces. It is not Made in China, it is just a costly thing with very less features. $2 would be correct price for it. This is … [Read more...]

We told you that solid wire is perfect for huge amount of work primary because breadboard jumper wires are costly. Here is how to create your own professional grade DIY breadboard jumper wires of any length with crimp pins, connector housing & other tools. Those jumper wires you buy has machine tooled pin … [Read more...]
Securing Jumper Wire Connections : Prototyping Daugterboard
There are many ways which we can use to secure the electrical wiring between a development board, basic electronic components and various modules, sensors to prevent loose connection, short circuit or wrong interpretation. Securing jumper wire connections is an important part of breadboard wiring. Prototyping daugterboard (prototyping shield) can help you securing the connections. In previous … [Read more...]
Nokia 5110 Arduino Wiring, Technical Details : Basic Arduino LCD
Previously we talked about choosing displays for Arduino. At that time we had no idea that Nokia 5110 Arduino modules are made out of used Nokia 5110 like thrown away phones. After knowing the background story, we really can not suggest this thing to buy. Buying a color LCD, TFT display for Arduino is correct option. Raspberry like single board computers supports high resolution displays and we … [Read more...]
DIY Basic Stand For TM1637 7 Segment LED Display Module
