| | | | | I wanted to explore the magic of RFID and I bought a simple card reader from Banggood which allows me to read and write 13.56MHz cards. The reader comes with one id tag and one card and it can be used to implement projects like a door security system or a payment system. The card and id tag that come with the board use classic mifare technology. Wiring I'm going to use Arduino Nano for this example, you can use Arduino UNO and perhaps other Arduino's too. You can't use any pin for the module board, you need to verify your Arduino's pin map and map them accordingly, for example, you can only use SCK on pin D13. | |

| | | | | Controlling Robot Wheels Last week, we figured out how to control a motor with a H-bridge. We expanded this to controlling a pair of wheels using the H-bridge. Above is a photo of the hardware. The wiring of the H-bridge is: H-bridge [+] and [-] are connected to a 9V battery H-bridge [IN1] to [IN4]... | |

| | | | | The Adafruit Feather RP2040 is an Adafruit Feather device that uses the same processor as a Raspberry Pi Pico. The Adafruit Music Maker FeatherWing is an audio playback shield designed for Adafruit Feather devices. After soldering headers or otherwise wiring the two devices together Adafruit's sample code can be used to play audio files. I found the sample code did not work for me. A reddit thread highlights the unofficial Arduino-Pico library. Using that library in the Arduino IDE along with some adjustments from the Flashgamer website got things working for me. | |
