    RGB Example

    by shedboy71

    In this example we will display the red, green and blue colours on an RGB LED I used a breakout which came as part of a kit, it was a common anode type Here is a schematic that shows how to connect this to your…

  • In this example we will flash an RGB LED using C Schematics Here is a schematic and layout Code This example requires wiringPi to be installed – http://wiringpi.com/download-and-install/  

  • 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 Compile as follows Run with this

  • 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…

  • The BMP180 is the new digital barometric pressure sensor of Bosch Sensortec, with a very high performance, which enables applications in advanced mobile devices, such as smart phones, tablet PCs and sports devices. It follows the BMP085 and brings many improvements, like the smaller size…

    Pi and PIR example

    by shedboy71

    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…

  • The DHT11 digital temperature and humidity sensor is a composite Sensor contains a calibrated digital signal output of the temperature and humidity. DHT11 uses a simplified single bus communication. Single bus that only one data line, the system of data exchange, control by a single…
