Gravity: 4 Channel Relay Shield for Arduino USB Style_No USB Range - 0cm to 600cmThis Relay Shield for Arduino acts like a switch. It is commonly used to control anything over 5V such as lamps, water pumps and garage doors. One of the most interesting projects for your boards is perhaps being able to control High power devices like Lamps, water pumps, garage doors and so on. But interfacing with high power is quite a dangerous task when building the circuitry. Relays allow for interfacing an external electrical circuit like a
