Now autumn is setting in, I’ve started doing some work on my control algorithms for my home temperature control system.
I had been using a simple On-Off (“bang-bang”) control system, but as expected, I was getting quite large temperature overshoots above the desired temperatures. In some cases, I was getting an overshoot of about 2C, which at times made things quite uncomfortable.
Since I had already done quite a bit of work on temperature control in other systems, I decided to improve on the system using a control methodology that has worked well for me in the past: PID control.(read more)

This week on the blog, we featured this super cute Honey Lemon purse from Jonathan Melchor on YouTube!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
