Connecting the Force Sensitive Resistor
Mission 1 Tutorial
Activity – General with Sensors (20 mins)
Start with all the parts of the Mission 1 on a table:
Jumping wires x 3
27 kΩ Resistor x 1
Ask the class to name and describe each component as you connect it to the Mission 1 in front of them. Explain briefly about each of these sensors and what they measure.
Demonstrate a simple use of the sensors already prearranged with a breadboard and jumper wires.
Follow through with the rest of the lesson using one of the available sensors. The students should be able to connect all the components on a breadboard and connect up to their Mission 1.
Once the hardware is assembled, up the Mission 1 view the data from the relevant sensor field.
Review the output of the sensor on the LCD and discuss the information.
Activity – Investigation (15 mins)
How much force can you apply to the pad?
Can you use the pressure pad to measure the mass of objects?
What if you used multiple pressure pads, how would you determine the mass?
What is the best way to apply the pad to measure pressure?
