Combination Locks Safety & Security - Padlocks & Hasps. The Transistor is used as a switch and it’s better to use an N-channel, the IRF510N is pretty popular when used with an Arduino, when you apply a 5V voltage across the Gate and the Source, the transistor becomes like a closed switch between the Drain and the Source, and it doesn’t need any resistor like bipolar ones.Īnd if there’s no voltage applied the transistor acts like an open switch, and this how we control the solenoid.įor the other example I’m using a 1 channel relay module, it works with 3.3V, and we control its input like controling the transistor, the only difference is that they are inverted (we’ll see in the code). Remember to upload the code first then uncomment line 62 to 64 and reupload, its done only once. Experience the reliability of our combination code lock.
