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...]

China Bicycle Speedometer Review
Possibly most families except the misfortunate have a bicycle. The "premium" China bicycle speedometers sells at $5 to $7 on Ebay, Amazon. Initial plan to develop a DIY speedometer with Arduino and TM1637 LED display dismissed as the unit costs lesser than half than DIY. Here is China bicycle speedometer review with infographics explaining functioning parts, pdf manual and how it really performs … [Read more...]
Convert Computer Power Supply To Breadboard Power Supply
All of us have, had died desktops with quite costly ATX, SFX power supply units. Those units are really great for powering DIY electronics compared to the cheap made in China circuits with AC mains to DC converter. The supplied power by a computer power supply would be stable. Here is how to convert computer power supply to breadboard power supply. How To Convert Computer Power Supply … [Read more...]
Breadboard Wiring Rules & Useful Hacks
It is not another article on breadboard wiring rules. Human who can read this webpage knows what is breadboard, breadboard power supply etc. Here are some extreme breadboard wiring rules & useful hacks to make the things easy for complicated circuits. Actually we are working with through hole technology components not SMD components, so 1960-70's various things work better. I will use least … [Read more...]
Raspberry Pi Cardboard Robot TJBot With IBM Watson API
In another article we have shown easy example of using IBM Watson's power of machine learning as a WordPress Plugin which can analyse the emotion or tone of post's text. Instead of server, if we use a hardware, the thing becomes as smart object and basic example of Internet of Things (IoT). In this guide we point how to use Raspberry Pi like single board computer & IBM Watson API to create … [Read more...]
What Resistor You Need For Which Colour Of LED
Of course you can blink a LED with Arduino or more easy - connect a LED to light it up. Previously we talked about basic electronic components, color coding of resistors, our free tool for calculating value of resistor and a guide possibly most important to may - multimeter guide for dummies. At minimum you should know what resistor you need for which colour of led, what should be the supply … [Read more...]
DIY Breadboard Jumper Wires : Crimp Pins & Connector Housing
We written before about breadboard jumper wires and solid wire for breadboard wiring. 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...]

In this article we will briefly discussed the commonly use gauge, types, numbers of jumper wire & solid wire for breadboard wiring. They are needed for hobby to serious electronics works. This will complete a part on basic matters around electronics works. Children also can … [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...]
