Pins 6, 7 are not going low

Other Hardware General Electronics

Hello,

I was testing the MOSFETs so as to understand how they work, as I want to use them as switches in my project. So, I made the following circuit as shown in the picture and code is also attached. However, the pins 6 and 7 are going HIGH but not coming back to LOW. Is there something wrong with the circuit or the program?
According to my circuit and logic ( which I assume) , the LEDs should turn ON and OFF, as I switch the states of pins 6 and 7 but the states of both the pins remain HIGH and are not affected by the LOW command that I gave in the code

they not going in simulation? is this simulator allow power disconnecting or it means everything is proper powered and user need to place only signal wire?

3

It was working fine with two MOSFETs. Yeah, I guess everything is powered properly and I only need to give the digital signal to those Pins so as to switch.

and why you decide to add useless FETs?

5

In my project I need to use four FETs for switching. So, before actually doing that, I was testing this basic circuit

6

and the reason is?

7

I need four FETs as switches. I will have to operate all 4 of them at various times as per the need

8

you need or project need? it is only 2 LEDs, also end device. for switching are 2 transistor needed, one for each LED.

this is neither arduino platform nor programming question. good luck.

just moved to the hardware section of the forum
