Feel free to reach out to me at CodeAllNight@outlook.com with any questions or leave them in the [issues section](https://github.com/jamisonderek/flipper-zero-tutorials/issues) for this project.
[tutorial](./firmware/updating/README.md) - The Flipper Zero makes updating the firmware simple and fairly safe. It is easy to build your own firmware as well using the fbt command.
[project](./gpio/wiegand/README.md) - This is a tool for reading and writing Wiegand data. Wiegand is typically used by NFC, RFID and keypads. This tool can be used to read a Wiegand signal, save and display the data on the Flipper Zero's screen. It can also play the signal back.
[tool](./gpio/pins/README.md) - This is a set of files you can copy to your Flipper Zero so that you can easily lookup the meaning of a pin.
### hc_sr04
[project](./gpio/hc_sr04/README.md) - This is an improvement over the original HC_SR04 library so that you can get mm accuracy in measurements. It displays ultrasonic distance in both inches/cm. The readme explains how the code gets more accurate timings.
### gpio-gpio-7segment
[project](./gpio/gpio_7segment/README.md) - This application can control a common-anode or common-cathode 7-segment display. When you click the OK button the display shows a random dice roll (1-6); but you can modify code to display any number from 0-9.
[tutorial](./gpio/gpio_interrupt_demo/README.md) - This is a "hello world" demonstration of triggering a callback when a GPIO pin transitions from VCC to GND.
[tutorial](./gpio/memsic_2125/README.md) - This is a demostration of using GPIO interrupts to interpret data from the Memsic 2125 (Mx2125) Dual-Axis Accelerometer.
[tutorial](./subghz/plugins/subghz_demo/README.md) - This is a demonstration of sending & receiving radio signals using the subghz_tx_rx worker library.
This is a two player game that uses the subghz_tx_rx worker library for communication. Two Flipper Zeros running this game can play Rock, Paper, Scissors against each other!
[project](./subghz/protocols/x10/README.md) - This is a protocol decoder for the Flipper Zero to decode the x10 series of devices when doing a read from the Sub-GHz menu.
