I am very new to electronics and dont have much knowledge on the project i am allocated with, so i hope to get some help here.
my project requires me to use a microcontroller (should not be an arduino) to digitize the data received by gyro sensor and communicate it over usb.
i have to keep lowest possible budget for the project.
the main question here is which sensor and microcontroller should i use.
i have seen some 3 axis sensors at farnell.com which cost approx 9 pounds. but i dont have a clue about which microcontroller would be compatible with the sensors.
I would be happy to receive any help on sensors and compatible microcontrollers.
Thanks in advance.
i need to communicate the data over a usb, so should i be looking something specific in micro controllers for that reason.
and the sensor i was looking at has a digital interface.
i’ll try looking up a few with analogue interface.
i confirmed with my professor it is
Gyro -> (analogue interface) -> microcontroller -> (USB interface) -> computer
but the analogue output gyro sensors i could find were all expensive costing approximately 55 pounds.
do you have any idea for cheaper sensors.
from farnell or rs components.
Almost all microcontrollers can accept digital input, and most can accept serial input, but not all can accept analog, PWM or I2C. Picaxe offers some of the least expensive microcontrollers out there. One of the least expensive Ethernet options we have is the ENC28J60 Ethernet Network Module and the Ethernet to Serial Web Server Module.
Choose an inexpensive Gyro but first check the interface. The easiest to work with is analog, so whichever microcontroller you choose, be sure it can accept analog and has an SPI.
So, to verify:
Gyro -> (digital interface) -> microcontroller -> (USB interface) -> computer
Picaxe need the USB download cable. If it’s not Arduino, then take a look at How to Make a Robot – Lesson 4: Understanding Microcontrollers to give you some guidance.
You can find here all the gyroscopes we carry: robotshop.com/sensors-gyroscopes.html
You can sort them by price to find the most affordable.
