MCP9808 digital temperature sensor example The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.5°C (max.) accuracy. The MCP9808 comes with user-programmable registers that provide flexibility for temperature sensing applications. The registers allow user-selectable settings such as Shutdown…

This is a follow on from the Raspberry PI and python example – http://www.pibits.net/code/raspberry-pi-and-74hc595-python-example.php This example uses wiringPi Schematic Code This example is C++, it will flash an LED one at a time connected to the 74HC595 Call this shift.c [codesyntax lang=”cpp”] #include <wiringPi.h> #include <stdio.h>…

In this example we expand the amount of outputs using a 74HC595 The 74HC595; 74HCT595 are 8-stage serial shift registers with a storage register and 3-state outputs. The registers have separate clocks. Data is shifted on the positive-going transitions of the shift register clock input…

In this example we connect a PIR module up to our Raspberry PI, this is quite a simple module to connect as it requires only 5v, Gnd and the output is PI friendly so does not require any level shifting. A passive infrared sensor (PIR…
