Hi Im a studying 2nd year computer science student and for a project for one of my courses i decided to make a remote control car but i have no knowledge of how to connect the motors or the individual parts I would need such as capacitors, diodes, etc. I know how to program but hardware part is the issue i do not want to fry my costly board. The remote controlled car should be able to go forward, turn left and right, and go backwards. The main parts I have and would preferably like to use because i already bought them are : (1) arduino uno, (1) robot builders shield v3, (1) sparkfun xbee shield so i can use my laptop as a remote, (2) 3v dc motors, and (1) 9v battery for power source. I am currently researching about this and trying to learn through youtube and google serches but if there is anyone out there who can give me any specific tips like what parts to buy and how to place onto bread board i would be extremely thankful because none of this is within my expertise im mostly a programmer.
Did you look at the guide for the shield?
Insert the shield over the Arduino. Place the shunt over the Power jumper and flip the switch On (towards the Power connector). The Arduino's LEDs will flicker and the Power LED will stay lit. Flip the switch Off and make your other needed connections on the prototyping area or on the Breadboard. Install the Arduino with the RBS on the robot and connect the motors, sensors, servos and other used peripherals....You can connect 2 DC motors to the screw terminals marked M1 and M2. The polarity does not matter much at first, just connect them and program the robot to go Forward. If one of the motors is turning the wrong way, swap it’s wires. The program the robot to turn Left. If the robot turns Right instead, swap the motors.
Yea i did but i havent conncected the motors and power yet i want to make sure if i do turn it on nothing will fry or my arduino will break. Also after a bunch of reading i did not know you needed a seperate battery pack to power the motor i thot the power source from arduino would carry over, so im going to power the arduino itself with the 9v battery and then the motors will be powered by 2 AA batteries.
That sounds reasonable.
