Anton Posted March 9, 2012 at 09:54 AM Posted March 9, 2012 at 09:54 AM Hey there, I think that an ultra sonic range-finder would be a very welcomed addition to the bricklets. They can serve many purposes in many different applications. BTW: Congrats with the award! Quote
Xenna Posted March 9, 2012 at 11:04 AM Posted March 9, 2012 at 11:04 AM Agreed, if they had one available with a 6m range, I would have ordered one today. OTOH, something like this http://www.sparkfun.com/products/9495 (5v power, analog out) should be easy to use with an Analog In bricklet, shouldn't it? Quote
borg Posted March 9, 2012 at 12:15 PM Posted March 9, 2012 at 12:15 PM Yes, you can use the XL-Maxsonar EZ4 with the Analog In Bricklet. We have an eye on this sensor already, the problem is that it is quite expensive for us to make a Bricklet for this in big quantaties (you can see the price of the sensor). We kind of stretched our financial means with the newest production. However, we will very likely have a Bricklet for one of the Maxsonar thingies by at least June. Quote
Anton Posted March 11, 2012 at 06:50 PM Author Posted March 11, 2012 at 06:50 PM I'm pretty new to all this, how would you use the XL-Maxsonar with the Analog In? One would have to interpret the signals somehow, I guess? Quote
borg Posted March 11, 2012 at 08:27 PM Posted March 11, 2012 at 08:27 PM For the XL-Maxsonar EZ4 it is really easy. You have to connect 3.3V to V+, GND to GND and the analog in port to pin 3. You can then call GetAnalogValue() on the Analog In Bricklet and to convert to cm just calculate analog_value/1024. The whole interpretation of the signal is done by the EZ4 itself. Thats of course nice, but you pay for that feature (the sensor costs ~50$). Quote
