Re: Maxbotix Ultrasonic Rangefinder - LV-EZ1

I was able to get good readings using this sensor with the suggestion you posted btidey. Almost identical to the example there except just using the PWM pin. Since I am also planning to use pi-blaster which configures all GPIO pins as outputs by default to run LED strips; that will conflict with set...

Re: Maxbotix Ultrasonic Rangefinder - LV-EZ1

Thanks btidey! Hadn't stumbled upon that one yet. I was instead trying to go off of a PIR sensor tutorial that he had on that same site. I plan on trying both the serial and PWM approaches (yes using the same PWM pin from the sensor as trigger and echo which I think will work since I was getting 1's...

Maxbotix Ultrasonic Rangefinder - LV-EZ1

I am trying to connect the following range sensor, http://www.adafruit.com/products/172, to my RPi to get the range values (works great on Arduino Uno). Data sheet is here: http://www.maxbotix.com/documents/MB1010_Datasheet.pdf. I have the +5V, GND, and PWM connected directly to the GPIO pins on the...

Re: Transistor Advice for RGB LED Strip Lights

Thanks for the info Burngate! For my project I am powering the LEDs using an external 12V 2A power supply. @zetec86 I am using the following schematic which may help you with your project as well: http://mitchtech.net/raspberry-pi-pwm-rgb-led-strip . My post may have been a bit preemptive since I co...

Re: Transistor Advice for RGB LED Strip Lights

I'm interested in this one too. I am using these transistors (N-Channel MOSFET 60V 30A ): https://www.sparkfun.com/products/10213. I have seen other tutorials that get this to work, but they all use an LED driver board. Works fine in a circuit with an Arduino Uno, but the same circuit when attached ...
