资源简介：
Based on RC522 and Arduino R3. RC522 does not have the capability to read signal strength. In this case, the code changes antenna gain to detect whether it can read the tag or not. It can only read 7 levels of signal strength and which is enough for a basic demonstration.
LCD is an optional choice for this. The LCD displays signal strength of reader in dB.
