With memcached, you can establish communication between Arduinos, Pi Picos, handhelds, and other small microcontrollers.
When you’re connecting your microcontrollers, you have some excellent networking options such as MQTT [1], Redis [2], and even SQL databases to choose from.
If you work with low-end hardware or have some software limitations, memcached [3] is another good option to consider: It is a high-performance, distributed memory key-value caching solution.
Memcached servers are supported on all major operating systems, and clients are available for almost all programming languages.
Memcached is commonly used in back-end web applications, but it can also be used in distributed microcontroller projects.
Small systems only require network sockets to access a memcached server.
This minimal requirement lets low-end hardware platforms such as gaming consoles (Figure 1) share information with Linux and Raspberry Pi systems.
Bash users will be happy to hear that it only takes a one-liner to get or set a memcached key value.
This last winter was colder than usual, so I built a simple home temperature monitoring system using some low-end hardware (Figure 2).
In this article, I’ll show you how I used memcached with Bash, Python, and socket connections for my monitoring project.

This practical caching tool can reduce the load on a web database server by as much as 90%.
Adding custom firmware to a handheld gaming device enhances your gaming experience and lets you write custom apps.
We show you how with Onion OS on a Miyoo Mini Plus.
Maybe we should listen to those network guys.
What cannot be measured cannot be improved.
Netdata lets you measure almost anything – at least as long as it’s about the performance and health of a Linux computer.
