Introduction: (Simple)easy Way to Get Analog/pwm Audio From Raspberry PI Zero and Also Connecting to Crt TV
- Here i have used a simplest method to feed audio to a tv along with compsite video .........
Step 1: Choosing a Resistor
the pink resistor that i used is of 600 ohms .....you can use any resistor above 250 ohms !!!!!!!!!.....inorder to protect raspi ...
Step 2: Wire the Jumpers to the Raspberry Pi
connect tv pin directly to the composite pins(red + and white -/gnd jumpers) and video cable(compsite)
connect the audio pin(pin 13) c the image.......... to black wire
you can also use PIN 18
we are using common ground for audio and video signals....so use the tv(-) as GND for audio cable also
Step 3: Connect to Tv
Here my black cable is video(YELLOW)
White cable is Audio(RED/WHITE)
Step 4: Open Terminal in Raspi
Making pi to use analog audio
open the terminal
paste this: sudo leafpad /boot/config.txt
add this line to the end of the file: dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4
save the file or hit (ctrl+s)
DONE!!! now reboot
We have a be nice policy.
Please be positive and constructive.
