아두이노 솔레노이드 작동 구성 문의

tag UID가 94 171 220 144인경우 솔레노이드 작동 하는 구성을 진행하고 있습니다.
아두이노 readMifare 예제 기본 소스에서 if문으로 해당 UID가 리딩 시 작동하도록 할 예정이었으나 릴레이에서
반응은 하나 솔레노이드에서는 반응이 없습니다. 구성이나 소스에 문제가 있는건가요?
UID는 읽고 해당 UID(94 171 220 144)일 경우에만 릴레이가 반응을 합니다.
보시고 댓글이나 메일 부탁드려요.. ㅜㅜ 메일 : yjh7185@etomato.com 1. 프로젝트 사용한 보드 종류 아두이노 wemos D1 R1, NFC PN532, 빵판, 5V 릴레이, 5v 솔레노이드
2. 사용한 개발 프로그램명 readMifare 예제 수정
3. 사용한 센서 모델명 5V 릴레이, 5v 솔레노이드
5. 소스코드 (주석 필수)

This example will wait for any ISO14443A card or tag, and
depending on the size of the UID will attempt to read from it.
If the card has a 4-byte UID it is probably a Mifare
Classic card, and the following steps are taken:
- Authenticate block 4 (the first block of Sector 1) using
the default KEYA of 0XFF 0XFF 0XFF 0XFF 0XFF 0XFF
- If authentication succeeds, we can then read any of the
4 blocks in that sector (though only block 4 is read here)
If the card has a 7-byte UID it is probably a Mifare
Ultralight card, and the 4 byte pages can be read directly.
Page 4 is read by default since this is the first 'general-
purpose' page on the tags.
This is an example sketch for the Adafruit PN532 NFC/RFID breakout boards
This library works with the Adafruit NFC breakout
