Tested with instructions from here (http://jeremyblythe.blogspot.rs/2012/09/raspberry-pi-hardware-spi-analog-inputs.html) and results was 0. Sensor is working with 5v, but it's giving output also on 3.3v (tested with multimeter). Also, I have connected 3.3v to CH0 to test will something happen but t...

Hello,

This is my schematics: Analog sensor is MQ-3: http://www.sigmaelectronica.net/mq-3-p-1956.html

I didn't said before, I have RasPiO Breakout Pro : http://rasp.io/breakoutpro

@fsr: I'm not sure that I figured out. I tested using python programs that I found on internet.

Hello, I'm trying to use mcp3008 to read signal form analog sensor. For wiring I used instructions from this address: http://www.raspberrypi-spy.co.uk/2013/10/analogue-sensors-on-the-raspberry-pi-using-an-mcp3008/ I performed software and firmware update. SPI is enabled in raspi-config. Python libra...

So I need these:

1 GPS module
1 Temperature sensor
1 USB to TTL adapter
1 Real Time Clock module
1 camera... PiCam or usb web camera

Is that correct ?

I hope that it's not forbidden to post links here :) http://www.ebay.com/itm/GPS-Add-on-GPS-Shiled-NEO-6-GPS-Module-Perfect-for-Raspberry-PI-/141622548272 This is GPRS module.

Hello, I need to build a system with raspberry PI. This system need to have GPS module, USB webcam attached, and temperature sensor that uses TTL for communication with other devices. What components I really need for this? Does I need some additional board that is used to attach these modules to ra...
