This is an old version of the tutorial for reference purposes. It has been replaced with RFIDuino Hello World
The first 'Hello World' sketch will scan for any tag. When it sees a tag it will sound the buzzer and light one of the onboard LEDs.
- Geekduino or other Arduino compatible microcontroller
- RFIDuino shield and antenna
- Micro USB cable for your Geekduino or cable for your Arduino compatible board
- A compatible RFID Tag -all tags on this page are compatible with the RFIDuino
- Connect your RFIDuino as shown.
- Load RFIDuino_helloworld1 onto your board. You can find this sketch under:
- Once loaded, leave your board connected to your computer for power
- Swipe any of your RFID tag across the antenna board.
- If everything is working properly, the buzzer will activate and the green light will flash
RFIDuino_helloworld1 is the most basic code to use the RFIDuino. The code will create an RFIDuino object
myrfid, and use it to run the
decodeTag function. This function looks for a tag swipe happening across the antenna. If this function is successful, it stores the data in an array and returns a
true signal. Once a tag swipe is detected, the buzzer and light are activated.
EXTRA CREDIT: Modify the program so that it turns on the Red LED instead of the green one.
