Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

Advances in embedded systems and sensors have enabled efficient, intelligent surveillance solutions that improve safety and control in transportation and automation applications. The system presented ...

For some, Halloween is starting to rival Christmas for setting up elaborate holiday decorations. Homeowners now spend many hours─and sometimes dollars─creating ghoulish displays of lit pumpkins, ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Functions to go a specified distance: Driving speed PWM (2.0 V) is the PWM value to use for driving a fixed distance. If it is set higher than RAMP_VALUE_OFFSET_SPEED_PWM (2.3 V), the software ...

Abstract: The line-following car is a basic functional prototype that demonstrates how embedded systems might be used to operate autonomous robots. This work builds an Arduino based autonomous line ...

Learning electronics? Then, chances are you already know what an Arduino is, or at the very least, you've heard of it. After all, it's among the most popular electronics platforms available in the ...

Abstract: Line follower robots are autonomous robots that detect the black line by infrared ray (IR) sensors which send and receive infrared waves to identify the black line. Moving along with ...

Many times like a multimeter, I expected to have a handy serial terminal nearby such that I will connect those two wires [Tx, Rx] of the probe and will be able to see whether the sensor is really ...
