I posted this in an earlier post:

What does the 78L05 do? I assumed it was a normal transistor but it looks to be something else? Sorry to be such a newb...

It's a 5V regulator.

The only ones I found with the part number 78L05 are hard to find. I assume the normal 7805 will work?

#### blueroomelectronics

##### Well-Known Member
Yes. The L = 100mA rated.

Try google first, the 7805 is WELL documented on the net.

This schematic uses the three pin IR module. What is the difference between them and the two pin IR detectors?

You need the three pin, it's has a small IC demodulator inside.

Well I got one built. After debugging some things I got it working. Now I have an issue with incoming data.

When I push a button on the remote I get random data coming in:

Code:
Outputting raw mode2 data.

btw, this is from one button push.

When I push the same button again, I get different data coming in.

Could this be the remote or is it something with my board?

What remote are you using? What's it set for?

One is a Toshiba CT-852 and the other is for our comcast cable box. Both give random data when pushing one button. The software I am using states that the remote is using a special repeat code. I just wanted to make sure that my receiver I spent some good time building is working right.

That is the raw data. You need different software to interpret it. Your hardware appears to be working correctly.

Why would the electronic companies that make those want to use data that changes each time you send it?
