Create a Flow Chart for the Dragster Challenge program Flow Charts Create a Flow Chart for the Dragster Challenge program Break task down into separate behaviors Identify whether each behavior is a Process or Decision block Put the labeled blocks in order (including Y/N on decision blocks) Use Arrows to show program flow Don’t forget the Start/End blocks

Flow Charts: Dragster Challenge Every Flow Chart block behavior must be created in NXT-G Every program has a Start block Some programs have an End block: Implied by dangling beam in NXT-G One Process block may imply more than one NXT-G block A Decision block always implies some type of input: sensor, button, timer, counter, bluetooth, etc.
