What do you need?
Power Supply:
The basic electrical specification for a power supply suitable for a Raspberry Pi is that it supplies a regulated 5V DC (direct current) and can supply a current of up to 700mA. (Figure 1)
Inserting the SD Card:
The Raspberry Pi doesn’t have a hard disk built in to it, so it uses a Micro SD card as its main storage. Before turning on your RPi make sure to insert the SD card in the slot (Figure 2)
Connecting a Monitor or TV:
The Raspberry Pi uses an HDMI (High Definition Multimedia Interface) connection for the video feed. If your monitor or TV has an HDMI socket, you can connect the Raspberry Pi directly to it (Figure1). If your monitor does not support HDMI, and supports VGA (Video Graphics Array), you can use a converter that converts the signal from HDMI format to VGA (Figure 3)
