    New product: Advancer Technologies Muscle Sensor v3

    - 17 July 2015

    Hello, Jesse.

    I talked to you earlier today when you called, but I wanted to post the answer here for anyone else who might have the same questions.

    It looks like the example you posted is the "Using an analog input to control servos" from the Maestro user's guide. The modified version of that example script that we used in this project can be found in the blog post above. Please note that this script expects the output from the muscle sensor to be connected to channel 0 on the Maestro and the servo to be connected to channel 1. If you want the script to work with the sensor connected to channel 5, you will need to modify it to do so. If you try to modify the script and continue to have trouble, you can post your modified script on our forum, and I would be happy to continue troubleshooting there.

    Also, please note that we used two 1S LiPo batteries in our setup, so the analog output of the muscle sensor in our demo was from 0V to roughly 3.7V. If you are using 9V batteries, your signal could be upwards of 9V, which is higher than the Maestro inputs support and could result in damage. You might consider reducing the voltage by either adjusting the gain potentiometer on the Muscle Sensor V3, or using a voltage divider circuit.

  • Two new motor driver shields for Arduino

    Two new motor driver shields for Arduino

    If you are comfortable figuring out the wiring yourself, both shields should work with the A-Star 32U4 Micro as a general purpose motor driver, since the Micro provides access to most of the pins available on the Leonardo. If you continue having problems getting it to work, you might post about it on our forum with more details about your setup. By the way, it might be more practical to use our more compact DRV8835 or A4990 carrier board with modules that do not have the common Arduino form factor (like the A-Star 32U4 Micro).

    You already quoted our stance and reasoning for it. Whether it's worth the hassle of rewiring your setup to avoid a probably small risk to a $7 part (and maybe your Arduino, depending on which one you're using) is up to you.

  • New NEMA 17 stepper motor with optional integrated lead screw

    Hello, Davec.

    The NEMA 17 stepper motor with a 28 cm threaded rod is the only stepper motor with lead screw that we currently carry. We are looking into the efficiency factor you mentioned; do you have examples of places that specify it?

    For the animated GIF, we used our DRV8825 Stepper Motor Driver Carrier, High Current. If you are looking for a low-voltage stepper motor driver, you might consider our DRV8834 carrier, which can handle the same amount of current as the DRV8825, but operates from 2.5 V to 10.8 V.

    Hello, Anon.

    As long as the specifications of your modified bilge pump are similar to those of the bilge pump you linked to, I do not see any obvious reasons why it wouldn't work.

    Hello.

    The Raspberry Pi cannot be connected to your PC as a USB peripheral, but it could be connected over Ethernet.

    Hello.

    It would depend on which board you are asking about. For a full list of compatible Arduino boards, you might try the Adafruit Shield Compatibility Guide:
