its control over external devices.Dry-reed Relay refers to the reed relays, which are compared with the general relays, and their switching speed and life are greatly improved. The use of the relay is very simple, only the level control of its pin to complete the control of the relay. After entering the source directory, enter in the terminal:CD "Grove-relay"sudo python relay.pyThe Rasbperry Pi will control the relay to switch on and off every 0.5 s

Compared to the Raspberry Pi 1 it has: A 900MHz quad-core ARM cortex-a7 CPU 1GB RAM Like the (Pi 1) Model B +, it also has: 4 USB Ports GPIO Pins Full HDMI port Ethernet Port Combined 3.5mm audio jack and composite video Camera Interface (CSI) Display Interface (DSI) Micro SD Card

sprinkler and an electric rice cooker. Therefore, the Raspberry Pi Plus relay can fully extend its control over external devices.

Yesterday made the control led, played the first, the rest of the feeling is very simple, here recordJust a couple of photos.Play the honey module only to find the law, generally this module, there will be three pins, VCC (3.3V or 5V power supply output PIN), GNC (for Gpio pin of GNC), out/(I/O) (corresponding to the gpio number of pins), if it is necessary to send information to the

a more complex input with timing. Here are two points to note: The SetMode is in BCM mode, and the pin used is the same as the BCM number corresponding to the pin graph. You can also set the physical PIN number to use SetMode (GPIO). BOARD). The input/output mode is input when receiving data/status relative to host or Raspberry Pi, output i²c I²c can be a bus to
