    We do not expect those sensors to work well with a source that cannot supply the amount of current they need to draw when they pulse. In general, if you do not follow the specifications for electronics, you should not expect them to work reliably.

    However, in this particular case (since your supply can output close to the current the sensor wants to draw) if you cannot use a source that can provide more current, you could probably still use the sensor with a large capacitor (>10 uF) between power and ground near the sensor board.

    Hello.

    Like the datasheet says, those Sharp distance sensors draw current in bursts. So, when supplied power, the sensor will draw some nominal amount of current until the LED is pulsed and the current drawn increases to more than 300mA briefly. After the pulse, the current decreases again to the nominal amount. The average current draw of the sensor (which is the average of the nominal and pulse currents) is, like you noticed, described as typically 33mA, and at max a value of 50mA. The carrier board does not add hardware that changes this current draw noticeably.

    Hello, Larry.

    Thanks for the feedback and video of Zippy; we love seeing our products in action! I think its especially neat that you opted for a pair of scooter wheels (and adapters) instead of the wheels that the Balanduino uses (which I think are Banebots wheels).

    Hello.

    Congratulations on winning that tournament!

    A few of us here are using the 15cm Sharp sensors on our mini-sumo robots, and they do not seem to be noticeably better or worse than the 10cm versions at detecting objects that do not reflect IR very well. If you want to look into this more, can you post the details of how you are using and comparing the two sensors on our forum ?

    Hello, nihuyaka.

    We do not know the details of how the firmware for the UM7-LT was developed. You might try contacting the manufacturer, CH Robotics, to learn more about that.

    Hello, David.

    Yeah, unfortunately we do not have an example for balancing an older robot using the Zumo shield. But if you want to try writing your own script, you could get a good start by taking a look at the Zumo32U4's Balancing sketch. If you get stuck, you might try posting to our forum:

    Hello, Ted.

    I did not have trouble uploading to the A-Star 32U4 Prime while working on my robot. However, in general, sometimes if the serial monitor window is left open while unplugging and replugging the A-Star, there can be problems. Those problems can be fixed by unplugging USB, closing all programs that might be using the serial port, and trying again. If you want help troubleshooting your particular problem, you can ask for help on our forum.

    Hello, Juan.

    Thank you for your interest in our sensors. We do not have any MinIMU-9 or AltIMU-10 examples for dsPIC microcontrollers. All of the coding examples we have available for our sensors can be found under the "Resources" tab of their product pages.

    Hello, Nathan.

    Thanks for letting us know what it was like working with them. That sounds like a fun project! If you have pictures or a write-up of it, it would be great if you shared it on our forum.
