Arduino 2WD smartcar motor and sensors shield
Description
This Is Ongoing Project. I Am Designing Arduino Shield For 2Wd Smartcar Like [This](Http://Www.Ebay.Com/Itm/Smart-Car-Robot-With-Chassis-And-Kit-Arduino-Controllable-New-From-Usa-/252388565405?Hash=Item3Ac387E19D:G:T7Uaaoswumfulixs) The Purpose Is To Create Shield That Will Allow Easy Connection Of Sensors And Control Of Two Motors Including Feedback From Motor Speed Sensors Like [This](Http://Www.Ebay.Com/Itm/Electric-Motor-Speed-Sensor-Module-Photoelectric-Sensors-Groove-Coupler-/181460158093?Hash=Item2A3Fde468D:G:66Gaaoswfcvuk7Ns). I Am Planning To Use: 1. Two Motors [Ebay](Http://Www.Ebay.Com/Itm/Smart-Car-Robot-Plastic-Tire-Wheel-With-Dc-3-6V-Gear-Motor-For-Arduino-/221891182052?Hash=Item33A9Bebde4:G:Nlqaaosweetv~Pap) Or From [Pololu](Https://Www.Pololu.Com/Product/181) 2. Three Hc-Sr04 Ultrasonic Distance Measuring Sensors 3. Photoresistor For Light Measurement. Something Like [This](Http://Www.Ebay.Com/Itm/20Pcs-Photo-Light-Sensitive-Resistor-Photoresistor-Optoresistor-5Mm-Gl5539-/261913220877?Hash=Item3Cfb3E970D:G:Sdkaaoswew5Vbnuc) 4. Possible Two Sharp Infrared Distance Measuring Sensors. 5. Two Motor Speed Photoelectric Sensors. Shield Includes Atmega328 Controller For Motors Control. Because I Want To Control Motors Using Speed Feedback From Motor Speed Sensors, I Think It Will Be Good To Have Dedicated Controller For This Task. The Idea Is That Main Arduino Board Will Only Need To Transfer Desired Speed For Each Motor Via I2C. Then Controller Located On Shield Will Control Motors Using Feedback From Speed Sensors.
