Most of the IR remotes work reliably within a range of 5 metres. The circuit complexity increases if you design a long range IR transmitter for reliable operation over a longer range, say, 10 metres. To double the range...
Here are some interesting facts, incidents, memorable events and little-known facts from the lives of scientists... Intel Inside Intel was founded by Robert Noyce, along with Gordon Moore and Andrew Grove. The headquarters building is named ‘Robert Noyce Building.’ While presently almost...
Here is a simple low range radio transmitter for transmission up to 25 metres. It is basically an AM modulator whose signal can be received on the normal AM radio. It can also be used as an AM radio...
Most ultrasonic transmitters and receivers are built around timer IC 555 or complementary metal-oxide semiconductor (CMOS) devices. These devices are preset-controlled variable oscillators. The preset value of the working frequency is likely to drift due to mechanical vibrations or...
Many industrial automation and process control solutions require precision sensing of multiple process or control variables. Such variables include temperature, load, force, light intensity, motion, position and voltage. TI’s newest family of embedded microcontrollers (MCUs), the MSP430i20xx series, provides...
