In this tutorial, you will learn how to connect a photoresistor to a BeagleBone Black. The tutorial can also be used for other resistive sensors such as FSRs or SoftPots.

In this tutorial, you will learn how to connect a temperature sensor to a BeagleBone Black.

In this tutorial, you will learn how to control an external LED using a BeagleBone Black (BBB) from Python.

In this tutorial, you will learn how to control your BeagleBone Black using SSH with just the USB lead supplied.

This project combines a whole heap of modules to enable a Raspberry Pi to power a large 1.2 inch 4 digit 7 segment display. A small switch switches the display between showing the temperature and the current time. The project uses a real-time clock (RTC) to ensure that the Pi always has the correct time, even if it is not connected to the Internet.

In this tutorial, you will learn how to use an Infrared remote with a Raspberry Pi configured as a media center. The IR receiver is attached to the GPIO connector on the Raspberry Pi.

The low cost and full HD video playing capabilities of the Raspberry Pi make it ideal for building your own media center. This will allow you to play music and videos through your Raspberry Pi onto a TV.

In this lesson, you will learn how to use a PIR movement detector with an Arduino and to have the Arduino communicate with a Python program running on your computer to send an email whenever movement is detected by the sensor.

In this lesson, you will learn how to setup your computer to use Arduino and how to set about the lessons that follow.

In this lesson, you will combine the PIR sensor from [Lesson 12] with the Powerswitch Tail 2 module from Adafruit, to automatically switch something on when movement is detected.

In this lesson, you will learn how to use the digital inputs on the GPIO connector with a door sensor and a PIR motion detector.

In this tutorial, you will learn how to attach a miniature display to your Raspberry Pi and to adjust the Pi's settings to reduce the resolution sufficiently to read the screen.

In this lesson, you will learn how to use a DS18B20 with the Raspberry Pi to take temperature readings. Since the Raspberry Pi has no ADC (Analog to Digital Converter), it cannot directly use an analog temperature sensor like the TMP36, making the DS18B20 a good choice for temperature sensing.

In this lesson, you will learn how to control a stepper motor using your Raspberry Pi and the same L293D motor control chip that you used with the DC motor in Lesson 9. The Lesson will also show you how to use an alternative driver chip, the ULN2803.

This lesson describes how to control both the speed and direction of a DC motor using Python and an L293D chip.
