I'm still trying to wrap my head around the PNP, NPN differences but if I wanted to use an NPN transistor here instead, could I just swap the flyback diode to the other leg of the transistor and wire into the grounded side? 5 years ago By connecting an L298 bridge IC to an Arduino, you can control a DC motor. NEVER do this when you're using digitalWrite and esp. This is a really bad idea in so many ways.The ultimate hardware killer. Insert your transistor on three separate lines of your breadboard, with the flat side facing outward. In the below step, HIGH and LOW refer to ON and OFF. You need to manually add IR Library to Arduino IDE as it is not included by default. start or stop the motor as well as provides DC BREAK for instant STOP One has to select arduino pins for the motor then start rotating motor using given library functions Note: If your motor needs more current than 200mA you can just buy another transistor (ask the staff in the electronics store). To run a motor in both directions, it's not obligatory buy a 'DRIVER' in the 'transistor contest' of this instructables. The EN A pin of IC is connected to the PWM pin 2 of Arduino. In this circuit, for controlling the speed of DC motor, we use a 100K ohm potentiometer to change the duty cycle of the PWM signal. To power the motor, you need to send 5V through it and then on to ground. Reply They are pretty similar but the collector and emitter are switched around. How to Connect a DC Motor and TIP120 to the Arduino. You mention that in order to source more than 200 mA a larger transistor is required, however the datasheet appears to say it can continuously source 600 mA. It would be very kind if you would either take it down or change it a little bit and make it better :) (This will help: http://embedded-lab.com/blog/wp-content/uploads/20... Saying that this is not the safest way to control a motor is putting it mildly. I believe it would be really frustrating and for some people even spirit crushing to fry their first arduino. You can damage your arduino because the pins can short out. the 2N2222 is a general purpose good transistor and the 1N4007 is an honest rectifier, hard to die. Connect second DC motor to Pin 11 and Pin 14 of L293D. To set the values of Arduino pins 8 and 9, we have used the digitalWrite() function, and to set the value of pin 2, we have to use the analogWrite() function.
