- Break doen the process into a series of simple steps, imput, process, output.
- Flowcharts
- Planning a program in an easy to read diagram.
- Some sensors give an analogue output - can give a range of values.
- E.G. LDRs and Thermistors
- The system can be programmed to do things at different resistances.
- E.G. LDRs and Thermistors
- How to use Simple Routines to Control Outputs
- Feedback Loop: sends the program back to anearlier point to do the same thing repeatedly. How sensors are monitored, goes round loop as king question untill answer changes.
- Count: Count how many times it gets a certain imput, then give an output energy x times.
- Tme Delay: "wait 10", program waits 10s then moves to next instruction. Use to make lights flash.
