We had a question from our customers if the Snowboard can be used with a single zone FSR (force sensing resistor) sensor. An answer was given in our last blog post and today we will go further with this issue.
Shortly speaking, the Snowboard can work with upto 160 single zone FSR sensors. All you need to do is to connect two ends of a sensor to appropriate pins of the Snowboard - One end to D pin and the other to A pin. D pins and A pins are configured as shown in the picture below:
In this post, we will add 3 single zone FSR sensors to the Snowboard.
Add them, upload a firmware and run a visualization application according to this instruction. Press each sensor and you can see the visual response of each sensor.
When you touch all of these sensors, the Snowboard can measure their responses simultaneously.
Did we tell you that an FSR matrix array sensor is technically a large combination of single zone FSR sensors? Yes it's true as each cross point of a row and a column in a matrix array sensor is actually a single zone FSR.
So, what does it mean? The answer is that you can add a single zone FSR sensor to Snowboard! Just pick up any single zone FSR and connect two ends of the sensor to D6 and A0 pins of Snowboard.
Connect the sensor, upload snowforce firmware, and launch snowforce processing application. That's all.
This week we've added a handy sample program that checks the speed of force sensing module of Snowborad.
Here's how to do it.
First, download the latest Snowboard Arduino library and installs it by consulting this link.
Choose File-Examples-forcespeed to open the sample program.
Upload the program.
Choose Tools-Serial Monitor to open Arduino's embedded serial terminal.
The serial monitor will open. Snowboard continuously reads 100 frames and outputs speed information as shown below.
We are currently experimenting with different force matrix sensor arrays to improve the performance and usability of Snowboard. Here are our demo videos. Enjoy!
