Pn22221/16/2024 ![]() ![]() A small transistor like the PN2222 can be used as a switch that uses just a little current from the Arduino digital. If we tried to connect the motor straight to an Arduino pin, there is a good chance that it could damage the Arduino. That will allow a higher value resistor with less variation due to the LED. The small DC motor, is likely to use more power than an Arduino digital output can handle directly. Actually because of device variations, I would not recommend using more than 2 LEDs in series from a 5V supply. If it is for pulse duty such as remote control the duty cycle is low and they can be driven at a higher current.įor continuous duty it looks like 20mA is the maximum.Īlso in your calculation for the LED series resistor you have not taken into account the voltage drop of the 2N7000 (or PN2222). I would use a drive it with 5-10mA of bias current with (that would be good for a collector current of 80mA), for example, a 470-ohm resistor. The voltage across the device should only be a few hundred millivolts while conducting and 80mA is no problem.Īctually, for this application, I would use a bipolar transistor (such as a PN2222). It really needs 5V to turn on well as can be seen from this datasheet graph: The gate threshold voltage worst case is 3V, but that is not the voltage for full conduction, that is only to pass 1mA. 3.3v may not be enough to drive it enough into conduction for your needs. However, the 2N7000 is not the ideal device to drive from 3.3v. Provided the FET turns on well it won't affect the current through the LEDs or the LED resistor calculation significantly. You can drive the gate directly from the processor. The Picture of Product is for reference only.You don't need any resistor at all at Rg. We only bear the customs clearance fee for our export goods.
