In Arduino how to measure exact time between two events
Distance sensing with ultrasonic sensor and Arduino. August 8, 2012. in Arduino, Sensors. I’ve always wanted to play around with Arduino Ultrasound sensor, but the idea of spending 30$ + shipping on a device that I may not use always sounded not that great.

Arduino: properly measuring time intervals Posted on November 17, 2015 by giannis When programming an Arduino it is sometimes useful or necessary to measure the time that elapsed between two certain points of the program’s execution.

AD8232 Heart Rate Monitor Hookup Guide lets look at what an ECG is representing and how we're able to sense it. The ECG is separated into two basic Intervals, the PR Interval and the QT Interval, described below. The closer to the heart the pads are, the better the measurement. The cables are color coded to help identify proper

The given project demonstrates how to measure frequency and duty cycle of pulses using arduino. In communication field frequency measurement is at most essential. Duty cycle is also an important parameter to measure because it gives % of the pulse width.

Measure rpm using hall effect sensor and show the measurement on a gauge. Use the measurement to adjust the pump speed . Does the hall sensor get its power from Arduino or from somewhere else? * how do times x and y change? User input, schedule or sequence? are there only 4 possibilities? Speed Control using Hall effect sensor. Charles
8232 measurement pulse heart monitoring hearbeat sensor
Each click or refresh of the drawing forces a new measurement. The response from the Arduino sketch to pfodApp is delayed until the new measurement is completed (~25mS) so that the latest value can be sent in the update. Arduino Sketch. The Arduino Sketch, lp_BLE_TempHumidity. ino, Advertising Interval, Max and Min Connection Intervals,
YoMo - The Arduino-based Smart Metering Board
Measuring Time Between Inputs. Currently your code is not working, because Arduino is fast enough to check the closed switch state many times before it opens again, so before calculating a new speed value, you need to see LOW on the input. You will now take a measurement. The Ardunio code loop will end and immediately restart
