How does the Play Computer work?

The Play Computer is a little computer that’s fun, easy to use and capable of doing many interesting things! It consists of various input devices, a processor and a few output devices. The input devices work as the eyes and ears of the device, they take in information made available to them. Next up, this information flows through onto the processor, which functions like the brain of the device. The Processor makes sense of the data received through the input devices and sends it to the output devices. The output devices are like our mouth and face, helping us speak and express. These output devices display the processed information in a way that humans can sense and understand. Only for the Play Computer, it can express through a screen and buzzer onboard. You can also connect a variety of other devices to the Play Computer, greatly broadening its output capabilities. This applies to input devices as well, letting you add on a whole new variety of exciting accessories.

List of 4 in 1 Sensors On Board

It’s a 4 in 1 sensors and it uses a APDS 9960 module. It can only work one at a time.
Pin Type GPIO
I2C_SEK I/O 27
I2C_SDA I/O 13
It’s a 4 in 1 sensors and it uses a APDS 9960 module. It can only work one at a time.
  1. Distance Sensor
    The Distance Sensor or Proximity Sensor is there so that the Play Computer senses when certain objects are near it. It sends out signals and senses for changes in the signal, such as the intensity and time taken to return when the signal returns to the sensor.

  2. Light Sensor
    The light sensor detects the light falling on it and than sends the signals out. You can make use of light sensor for a project, to perform actions when light is detected.

  3. Colour Sensor
    This sensor senses changes in the intensity of colour on objects and surfaces that it is programmed to read. For example, if you wanted to make a device that only drew patterns on red coloured paper, you’d need the colour sensor. Instead to make the colour sensor work, the smile LEDs must be ON.

  4. Gesture Sensor
    The Play Computer is also capable of recognizing various real time gestures that the user will make using their hands. It can be programmed to look for and recognize specific motions. For example, you can program the device to play a jingle every time it is shaken, which is only possible with gesture recognition. The maximum distance for the gesture sensor to work is 1.5cm.
