Arduino and 2 MOSFETs

I want to turn on 2 bulbs using 2 MOSFETs. The problem is that they both turn on when it should turn up just one light. Code: void setup() { pinMode(13, OUTPUT); pinMode(7, OUTPUT); } void loop() { digitalWrite(13,1); …

Using an Arduino to switching a grounded load powered by a 12 Volt supply

I wish to use a MOSFET to drive a 12V rated LED strip from an Arduino. The negative side of the LED strip must be connected to ground, so that means that the driving MOSFET must be between +12V and the LED strip. This is what I have tried so far.…

How to connect IRLZ44N to Arduino?

simulate this circuit – Schematic created using CircuitLab In above schematic; what value should R1 have? is it even needed? do we need that pull down resistor(R2)? if yes, 10K is enough or we need higher value like 100K resistor there? IRLZ44N…

Minimum separation of MOSFET

I have three MOSFET in a row, each separated about 2.5mm apart with the backs facing each other. Is this a good idea? N.B Each MOSFET will be sinking 20mA and 60 mA in total for all three MOSFET. I am using an IRF540. The schematic below is for ONE…
