Arduino is a microcontroller designed for real-time hardware control with very low power use. Raspberry Pi is a full computer that runs operating systems and handles complex tasks. Arduino excels at ...

The table shows the pin configuration of the Arduino UNO–based robotic arm. The red (VCC) wires of all servos are connected ...

Here we designed a simple non contact tachometer using microcontroller which can measure speed with an accuracy of 1 rev/sec. Here we design a simple non-contact tachometer using microcontroller, ...

Not every DIY project needs a Raspberry Pi ...

Many small microcontrollers require so little power that often they can draw what they need through their loads. This can simplify a system, reduce its cost, increase its reliability, and provide ...

Temperature-indicator and temperature-based products have generated wide interest. There are numerous applications for such devices with many possible solutions, each with its own advantages and ...

In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...
