Smart temperature control with a Raspberry Pi Pico #RaspberryPiPico #Python @Hackaday @veeb1337
Heat-o-matic is a proportional integral derivative (PID) controller that will be used to run a home-made precision heater. PID is a fancy way of saying that the code plays a game of ‘Warmer’, ‘Colder’ to get something to a particular value (in our example, a particular temperature). The internet is littered with examples of these things, so it is primarily a didactic exercise that will use a few bits of code we’ve previously developed, and hopefully it will make us a little smarter along the way.
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.
