Hello, I'm working in a very simple project where I use a PIR motion sensor to run a little DC motor.
I'm using 4 AAA batteries so 6v, and I got the motor from an old walkman that used 3v to run.
Whenever I test the motor directly with as low as 1.5v it works perfectly.
When placing the Mosfet and the PIR sensor in the circuit I'm measuring around 5.3v at the end. That should be more than enough.
The problem is whenever I connect the motor the voltage drops to 1.5v. It runs, but too low to make it do anything.
The Mosfet is a 88L02S
And the PIR
Here's the circuit :
Thanks for your help.
