I have connected two 9V DC motors to my arduino and have attached an IR sensor on the breadboard as well. I have an IR remote control and want to power the motors via the remote but I have no clue what to write for the code. Can someone help me write the code and also can I get good references to a "dictionary" I guess you can call it for the arduino programming language. Thanks!
just google this
"c programming kernighan and ritchie pdf" and you should find several references
the two names there where the authors of C way back in the Bell Labs days, they basically invented it
As the Arduino is not using C++ or even modern variants of C, this will be a good starting point for you
as it wont get you doing things that are not available
there is also this Arduino - Learn the basics
As for you motors, how have you connected them (You did not mention). The Arduino is not compatible with 9V devices and it also does not have the drive capability to dive motors (Maybe the smallest low voltage low power ones but that's still a bad idea) so I am concerned you may be setting your self up to damage you Arduino.
This is a bad way, with the back EMF of the motor you can easily blow the controller as there is NO protection Simple 2-way motor control for the Arduino
Many people claim the 328 can sink or source up to 40mA, this is from the ABSOLURE MAX specifications and therefor not recommended
this is an excerpt from the data sheet
Although each I/O port can sink more than the test conditions (20 mA at VCC = 5V, 10 mA at VCC = 3V) under steady state
1] The sum of all IOL, for ports C0 - C5, ADC7, ADC6 should not exceed 100 mA.
2] The sum of all IOL, for ports B0 - B5, D5 - D7, XTAL1, XTAL2 should not exceed 100 mA.
3] The sum of all IOL, for ports D0 - D4, RESET should not exceed 100 mA.
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink
current greater than the listed test condition.
(Which is 20mA)
this is a better way to drive a motor (he voltage can vary as needed to the motor so in your case 9 V will work without any change to the circuit
this will drive a motor on and off but not reverse, you will need an H Bridge circuit for that, google "Arduino motor H Bridge" and you will find plenty to help
Take a photo on you cell, camera or just sketch it out in your favorite drawing program if needed and post it here
We can then help better
