Status LEDs
The meaning behind the blinking
Raspberry Pi LEDs
The Raspberry Pi has two LED lights that convey information about its status.
Red (power) LED
Red (power) | Status :— | :— (solid red) | Low power - Try a more powerful power supply or a different cable. (blinking red) | Low power - Try a more powerful power supply or a different cable. (off) | No power / low power - Plug in to a 5V, 3A power supply.
Green (activity) LED
| Green (activity) | Status |
|---|---|
| (solid green) | Busy working/booting |
| (blinking randomly) | Busy working/booting |
| (blinking consistently) | Network disconnected or emergency stopped - Configure FarmBot, press in the Web App, or check that the network FarmBot is connected to is online. |
| (off) | Ready and waiting for the next task |
Electronics box LEDs
In addition to the LEDs located on the Raspberry Pi, Genesis v1.4+ kits feature LEDs mounted on top of the electronics box.
LED 1 (sync)
This green LED indicates the sync status between FarmBot and the web app. It is connected to Raspberry Pi GPIO BCM pin 24.
| Green (sync) | Status |
|---|---|
| (solid green) | Synced and ready |
| (blinking slowly) | Needs sync (Will not execute any unsynced events or sequences) |
| (blinking quickly) | Syncing |
| (off) | Offline - Check the connection status LED |
LED 2 (connection)
This blue LED indicates the connection status between FarmBot and the internet and web app. It is connected to Raspberry Pi GPIO BCM pin 25.
| Blue (connection) | Status |
|---|---|
| (solid blue) | Connected and working |
| (blinking slowly) | Needs configuration - Configure FarmBot, press in the Web App, or check that the network FarmBot is connected to is online. |
| (off) | Offline - Check your internet connection. If you are connected to the internet but the Blue LED is off, one or more of your ports may be blocked. Get your network administrator to check the ports listed in the Firewall is blocking network traffic troubleshooting section. |
LED 3 (custom)
This white LED is user controllable via the Control Peripheral sequence command. It is connected to Raspberry Pi GPIO BCM pin 12.
LED 4 (custom)
This white LED is user controllable via the Control Peripheral sequence command. It is connected to Raspberry Pi GPIO BCM pin 13.
Electronics box buttons
Some kits also include push buttons featuring integrated LED lights.
E-Stop Button
The E-Stop Button (included with all Genesis v1.4+ and Express v1.0+ kits) has a red LED that indicates if FarmBot is or not. It is connected to Raspberry Pi GPIO BCM pin 17.
| Red (E-stop) | Status |
|---|---|
| (solid red) | Unlocked and ready |
| (off) | Locked - Check the Button 2 LED status |
Unlock Button
The Unlock Button (included with all Genesis v1.4+) has a yellow LED that indicates if FarmBot is or not. It is connected to Raspberry Pi GPIO BCM pin 23.
| Yellow (unlock) | Status |
|---|---|
| (blinking) | Locked - When safe to do so, press this button to unlock FarmBot. |
| (off) | Unlocked and ready |
