Hi guys,
I am new to this so please take it easy.
I need help in desiging circuit to drive relay.
I have basic idea but I am not able to figure out what value of resistance I should use for base of driving transitor.
If I am correct I think max output current of F2812 is 4mAmp.
So I can use 3.3/4m= around 1K or higher. And make sure Transistor goes into saturation to drive relay.
Can anyone help me out here ?
