how to put l7805 on breadboard
Ok I have a 240V to 6V AC transformer. It has a maximum current output of 1.2A.
I connected it to a diode rectifier and it produces 6.45V DC. When I connect this to my micro controller circuit, the micro controller doesnt initialize and my circuit doesnt work.
Then I checked and saw that the voltage was around 4.41V at the micro controller VDD.
The LCD connected to the micro controller doesnt show anything just half of the first row black boxes.
Any ideas on why?
This is my microcontroller circuit if it helps...
**broken link removed**
Basically I control an AC heater load via a optocoupler. Rather than powering the microcontroller circuity with Batteries I want to use the same plug point as the heater through a transformer of course...
