I have recently bought an mma7361l accelerometer. I simply want to be able to read data from. It seems as if I need to use I2c, but that's all I know, there is a lack of documentation for this accelerometer. May I get some help with wiring this accelerometer, using I2c, and reading info that I can use in python? Thank you.
The MMA7361 (assuming you've got the bare module) produces 3 analog outputs. Unfortunately, the Raspberry Pi has no analog inputs. However, you could use an analog-to-digital converter chip (e.g. the MCP3008) to read those analog outputs. See here for a tutorial on using the MCP3008 with the GPIO Zero Python library: http://raspi.tv/2016/using-mcp3008-to-measure-temperature-with-gpio-zero-and-raspio-pro-hat
The alternative is to use an Arduino (see this tutorial: http://www.electroschematics.com/10467/learn-use-mma7361/) and transmit to the Pi over serial.
