Electronics Worksheet: Project Planning

Electronics lesson 29: Project planning: input → process → output · Set 66 · 40 questions

Remember (Input, process, output): Input = what is sensed (a reading, a button press). Process = what the program decides (compare with a limit, count). Output = what happens (pump on, buzzer, LED, phone alert). Plan → draw → build with an adult → test.
