Measure your heartbeat with Arduino (Sensor XD-58C) Hello everyone! In this article we will go to realize a project with Arduino using the XD-58C sensor. This sensor does nothing but measure heart rate of the heart, it can be found in any medical equipment that is used in measuring heart rate. It can be worn on the finger or on the earlobe.

Pulse compression is a signal processing technique commonly used by radar, Conclusion: to increase the resolution, the pulse length must be reduced. Example (simple impulsion): transmitted signal in red (carrier 10 hertz, amplitude 1, duration 1 second) and two echoes (in blue).

Decoding and Sending 433MHz RF Codes with Arduino and RC-Switch. TUTORIALS. Upload it and open the serial monitor. Hold your remote near your receiver module and press a button. The Arduino should decode the signal and print the results in the serial monitor. Note the pulse length has to be manually set because it differs from the

Decoding and Sending 433MHz RF Codes With Arduino and Rc

The following code – based on the “SendDemo” sketch – switches one of my remote controlled mains switches on and off every 1 second. Note the pulse length has to be manually set because it differs from the default pulse length for Protocol 1.

Arduino read pulse-width frequency and duty cycle from a

Reads a pulse (either HIGH or LOW) on a pin. For example, if value is HIGH , pulseIn() waits for the pin to go HIGH , starts timing, then waits for the pin to go LOW and stops timing. Returns the length of the pulse in microseconds.
