Click2Duino is an open source, low-cost emergency vehicle gate entry device. It is designed to be an inexpensive alternative to devices such as Click2Enter and siren activated gate operating devices.

• Arduino (Uno, Nano, etc.)
• RGB LED
• 433 MHz Receiver Module
• Relay
• Jumper Wires & Breadboard
• Security Wire (for connecting to gate control module)
• Mounting hardware

This code was written to meet C2E specs with some improvements.

• If user holds down PTT for too long, the LED turns orange for as long as the button is held down or 2 seconds minimum. This helps with troubleshooting in cases where there is interference. If the LED were left off, it could be mistaken for a power issue.
• Use of a single RGB LED instead of two separate LEDs.
