GYROSCOPE Gyro L3G4200D detects or measure rotation on 3 axis: x, y and z. It has three selectable scales: 250 , 500 or 2000 deg/sec. Gyros are not affected by gravity (like accelerometers) and can give you exact information how object is orientated. Gyros and accelerometers are often used together because of great complement to […]
As it turned out re – exchanging those buttons for PIRs was a lot more complicated then expexted. When I simply plugged in the sensors, they didn’t work properly. After a lot of testing I figured, that at least two of the eLab’s three PIRs appeared to be broken. I ordered new ones from Tinkersoup, […]
To recreate a sensor using textiles, I recreated a knit pressure sensor. I knitted a little rectangle, connected it with crocodile clips to the breadboard and using Arduino and an LED created a presure sensor. knit pressuresensor from Jessica Snidersich on Vimeo.

Just a quick update: I managed to implement the millis() function correctly into my code. Before the sound was only triggered, when both pedestrian and cyclist are detected simultaniously. Now it also triggers, when a bike is detected and a pedestrian has been detected recently (within the last four seconds). So I’ve got the main […]
These are notes I took for myself, that helped me understand and remember how to implement Serial communication in my code. Serial communication can be very important for troubleshooting, to see what bits of the code are working properly and which aren’t. It can also necessary for extra functions like for example communication data to […]
