Motorized Drawbridge without //control.Node • ME-7038

This version is offered for customers who already have a //control.Node (PS-3232). ME-7028 Motorized Drawbridge is the total kit with a //control.Node.

Build this drawbridge from PASCO Structures, add a stepper motor and gears, and raise and lower it using code you write. This bridge kit also includes a Wireless Load Cell/Accelerometer that can be used to measure forces within the bridge while it moves.

How It Works

• Students build the drawbridge using step-by-step illustrated instructions. Then they use Blockly coding (imbedded in PASCO's Capstone or SPARKvue software) to program the drawbridge to raise and lower.
• Three sets of gears allow students to investigate the effects of different gear ratios.
• The Load Cell can be added to various places in the bridge to measure loads while the bridge moves. The load is displayed on a graph in real time.
• The Load Cell can be used as a limit switch to stop the bridge movement when the bridge arm pushes on the load cell.
• The speaker in the //control.Node can be programmed to beep or play music to warn when the bridge is going to move.
• The accelerometer in the //control.Node can be used to control the drawbridge movement in response to a change in acceleration, such as simply turning the //control.Node upside-down.
