A Guide to Powering your Arduino
The Arduino was invented primarily for non-engineers but now, a lot of engineers are also into it Using it in a fully-developed project is not a good look, yes, but it’s a lot...

Fingerprint sensors are old technology but it wasn’t readily available to makers until it was cheap With such a device, you could easily create a keyless secure lock, biometric...
A finite state machine (FSM) is a theoretical machine that only has one action or state at a time The machine may go from one state to another if there are inputs (or one input)...
The MQ-4 is one of many gas sensors ready to be interfaced with microcontrollers Just like the rest of the MQ sensors, the MQ-4 is most sensitive to a particular gas This time,...
The BH1750 is a light-intensity sensor that interfaces with a microcontroller through the I2C bus It can directly provide lux values without further processing, unlike CdS cells...
How can you create sine, square or triangular waves with Arduino Apparently, there’s a way with the help of an IC package -- the AD9833 With it, you can now create waveforms for...
In Arduino programming, we learn about functions setup() and loop() Any code inside setup() executes once while code inside loop() executes again and again until the next...
A seven segment display has one pin for each of its seven segments This means if directly interfaced with a microcontroller, you will need at least seven pins Fortunately, there...
Measuring an object’s weight can sometimes be part of a bigger project And unless you have a good reason, you wouldn’t want to use an analog weighing scale A digital weight...
I believe what makes Arduino popular is how it makes microcontrollers easier to use I remember the time when I have to spent hours coding a project and then spend money on...
