Green Led Blinking and Tv-b-gone not working

Post by senra »

Hi,
I'm trying to assemble a tv-b-gone in a breadboard and it is not working. I'm using the v1.2 firmware and hardware. After all the work the green led blinks every 3 seconds and the IR leds blinks randomly. I don't know what causes that. Anyone can help me?
Sorry for my bad english, I'm from Brazil.

Check all your breadboard connections and make sure you have adequate power. The IR leds draw a lot of current and a voltage drop could cause the processor to reset.

I checked the connections twice and I'm using now a 5v power supply ( before I was using 2 AA batteries). The led still blinking every 3 seconds but now it is blinking brigther. I followed the instructables page to burn the firmware in to a blank attiny85 using an Arduino Uno as ISP, can it be the problem?
Thanks for the fast answer.

Try disconnecting all but one of the IR leds.

I've disconnected everything except one of the IR leds but the problem still happening. The IR led still blinking slowly, I've tested it in my Tv and I couldn't turn it on/off.

the problem still happening.
Is it still blinking every 3 seconds, or did anything change?

Still blinking every 3 seconds. I suspect that I don't know how to burn the firmware in to the attiny85 20pu.

I would expect no blink at all if the chip were not programmed. If you post a photo of your setup we can try to spot the problem.
