Raspberry Pi Tutorials

This tutorial will show you how to make the reading of a sensor audible. In this example, we will be using the HC-SR04 Ultrasonic sensor, but it can be applied to most, if not all, other sensors. To do this, you will need to have the ultrasonic sensor working, which you can read here: https://www.modmypi.com/blog/hc-sr04-ultrasonic-range-sensor-on-the-raspberry-pi You will also need text-to-speech software. There are a few different ones, but we are using espeak. To install it open a terminal and type in: sudo apt-get install espeak Once this is done, your raspberry pi is ready to talk to you. The basic idea...

So you've just received your Zero Delay Arcade USB Encoder and its time to wire it up! Start by getting the USB Encoder PCB board and take note of the connections. We are going to wire up the Joystick first, so grab that and the ribbon cable. Plug one end of the ribbon cable into the joystick port, then plug the other end onto the 5 pins on the joystick. Make sure to get the orientation correct, which is white side of the ribbon facing up, towards the red ball on the joystick Once we've got that sorted, we can...

Please Note. This method combats mechanical compatibility between the Raspberry Pi Model B & Model B+. Electronic compatibility is a little different, please see below. So you've got your shiny new Raspberry Pi Model B+! Great!  But there's a problem! That 26 pin ribbon cable you had for your old Model B doesn't seem to fit :( In addition, that big breakout board you want to use doesn't fit either! The extra pair of USB ports and GPIO increase to 40 pins (which are fantastic additions and add a LOT of functionality) unfortunately do cause some issues in terms of mechanical back-compatibility with Raspberry...

Wiring up the sensor First things first, let’s connect the sensor to the Raspberry Pi. Red wire connects to pin 1 Black wire connects to pin 6 Yellow wire connects to GPIO4 pin 7 (you can connect this wire to any of the GPIO pins, just make note of which one as we need to know which pin to listen on) Installing the required software The guys over at Adafruit have provided some software to interface with the sensor, which is available on github https://github.com/adafruit/Adafruit_Python_DHT. Make sure you are in a suitable directory, e.g /home/pi cd /home/pi Then run the...

The laser-cut parts of the case are protected by an adhesive film which needs to be removed before assembly.
