Easy Very Low Power BLE in Arduino Part 2 -- Temperature

The Arduino does not sample at precise intervals unless we force it to do so (with some difficulty). If the Arduino is looping, or calculating, there is a certain amount of CPU time being dedicated to those tasks. Data collection is not the primary focus of the Arduino, indeed it seems more like an afterthought.

Measuring Voltage with Arduino - Starting Electronics

Blink Without Delay. Sometimes you need to do two things at once. For example you might want to blink an LED while reading a button press. In this case, you can't use delay(), because Arduino pauses your program during the delay(). If the button is pressed while Arduino is paused waiting for the delay() to pass, your program will miss the button press.

How to Read Temperatures With Arduino. by Ben Miller 13 Sep 2013. Difficulty: Beginner Length: Medium Languages: Electronics. Reading the temperature with an Arduino is an extremely useful function. It's the sort of function that is essential in many projects ranging from building your own home thermostat to creating a weather station.

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

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
