In RaspAP, I could make settings changes in the Hotspot area, but could not start the Hotspot -- meaning that WiFi could not be turned on. In the upper left corner of the RaspAP GUI is some indicator lights, with a blinking red light saying Hotspot was inactive. All other indicators sai...
The Raspberry Pi has 40 GPIO pins that connect to sensors, lights, motors and other devices. Here's a map and detailed explanation of what each does, including on the Pi 4.
It’s great to have a few things that simplify the experience of running all of this equipment too, without the solution itself causing more problems than it solves, like these network-operated Raspberry Pi-powered tally lights. A tally light is the light on a camera that lets the person ...
Both of the Ethernet ports on the back have functional link and activity lights. Each slotalsohas appropriately-colored link and activity lights. Each slot also has a power indicator LED, plus there's an overall board power LED, and an LED to indicate the MCU is 'on' (helpful when decidi...
The Green LED connected to the Digital PIN 4 is a visual indicator that lights up when the UNO has received all sections of the IR Code from the Python client running on the Raspberry Pi. Having this LED light up will confirm that the Serial communication between the Raspberry Pi and the...
