DIY Pulse Oximeter
Shinganapure Mar 12,2022
Step 1: Basic PrincipleHow An Oximeter works?Basically Oximeter calculates the percentage oxygen saturation in the blood on basis of amount of different light absorb in it. Oximeter has One photodiode and two LEDs one is Red LED & another one is InfraRed LED, both LEDs are switched one by one on a certain frequency. To take measurements fingertip is placed in between of photodiode and LEDs as shown in the picture. Oxygenated blood absorbs more Infrared Light and passthrough the more red ligh...

3 line to 32 line output expander
Yap Mar 04,2022
This project is described at Hackaday.The minimum lines required to use this board are: GND, SER (data), SRCLK (shift), RCLK (strobe). Vcc depends on the power arrangement. You should jumper the ~OESEL (output enable select) to ground if you don't wish to disable the display by signal, or vary the output with PWM, from a controller. The ~SRCLR input is only needed for resetting the output by the controller.This board is designed with optional aspects you can choose to include or not:As mentioned...
