One of those things is receiving instructions. delay) for 10 seconds.and you're not allowed to do anything else except wait for 10 seconds before being able to get back to what you were supposed to be going before.Īnd.what other important things could the program need to do (without getting held up)?. It is as if I am tell you to count to peel potatoes, and then somebody tells you to do nothing (ie. the whole program will basically become disabled (hanging here) until the amount of delay time has been completed.
the reason is because when this function is activated. even though the 'delay' function is part of the toolset. then connect that ground terminal to the arduino's ground terminal.Īlso. You can then focus on driving the robot's motors when you're sure that you can reliably control the L298N's output voltages.Īlso, if your L298N has a ground terminal.
#L298N MOTOR DRIVER ARDUINO CODE FULL#
Then you can be sure that you have full control of those terminal voltages (with software).
#L298N MOTOR DRIVER ARDUINO CODE CODE#
then proceed to use more code to test the other pair of terminals. If both of these pieces of code works reliably. Then.change the code so that it manually removes that voltage across those terminals. And just write the shortest piece of program you can that will produce a voltage across one of the output terminals of the L298N. don't even have the motors connected to the L298N. Usually, the first thing to do is to start with the simplest piece of code for testing the L298N outputs.
What you've done is the 'holy grail' of 'what not to do'. I've modified my code lately, this is the new one:ĭigitalWrite(Motor_B_Enable,LOW) //stop drivingĭigitalWrite(Motor_A_Backward,LOW) //setting motorA's directionĭigitalWrite(Motor_B_Forward,LOW) //setting motorB's direction Well, I'm working on an arduino car, like this one in this tutorial: Smartphone Controlled Arduino 4WD Robot Car ( Part - II ) - YouTubeīut I'm doing this without a bluetooth module. I don't know, for sure, if the problem is withing my code.ĭigitalWrite(int2,LOW) //setting motorA's directionĭigitalWrite(int4,LOW) //setting motorB's direction I tried to modify my code, but always in vain. I made a code, but when I finish uploading it, I power my Motor and Arduino, but nothing happens!
I'm trying to connect to a motor L298n an Arduino UNO.
