On Saturday, August 13, 2022 we will be working on the Adafruit Customer Support Forums. If you visit over the weekend and things are not complete yet, please check back later, https://adafruit.com/forumupdates
The Raspberry Pi is an amazing, tiny and inexpensive computer based on Linux. Despite being small and cheap, a Raspberry Pi system packs enough power to perform network management tasks using appropriate software tools. In this article, we introduce you to such a tool called Multi Router Traffic Grapher (MRTG) that uses Simple Network Management Protocol (SNMP) to monitor network devices and draw graphs showing how much traffic has passed through interfaces over time. We will also take some time refreshing your memories about SNMP, the protocol used by MRTG. We then cover how to install and configure MRTG on a Raspberry Pi system. The ability to visually monitor traffic load on network links at a glance, as explained in this article, is very useful in a Network Operations Center (NOC) environment.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
