The next item on the list is a pulse sensor from pulsesensor.com. Easy to connect with the Arduino UNO and it works out of the box. It is rather sensitive, so hold it gently against the index finger – do not push it as that will stop the blood flow! If the serial is being …
In physical interaction design it is essential to get a craftsmanship feeling for the interaction – how does the button feel to press, what happens when the artifact is touched, how responsive is the slider and how does it fit in, etc. An easy toolkit to get started with building basic mockups for the simplest …
Downloaded small footprint Minibian and Used Win 32 Disk Imager to put it onto an SD card. Realized that the device had to be registered for the network. Eeehk. Ok, it boots at least. Apparently it is quite possible to control an Arduino board from a RPI. This way one can use python rather than …
Onto the Arduino platform. It has its own IDE based on Processing. It is more C/C++ oriented than e.g. Phidgets. Gemma check. Including library for neo-pixel check (In the menu). USBtinyISP programmer check. Got an error: avrdude: error: usbtiny_receive: (expected 4, got -5) But it did upload the program and thus it works. Good enough, …
Here is the source for a sensor – in this case just a slider – connected to a servo, each phidget connected to plain USB. import com.phidgets.*; import com.phidgets.event.*; InterfaceKitPhidget ikp; AdvancedServoPhidget asp; float sensorVal; void setup() { size(400, 300); fill(255, 0, 0); setupServo(); setupIK(); } void draw() { readIK(); // clear the previous frame, …
Apparently ServoPhidget has been deprecated. Use AdvancedServoPhidget instead. Typical symptoms are that waitForAttachment() does not appear to work since it cannot find the device at all.
