Without a doubt, FM transmitter and Receiver are among the top favorite electronic project topics, however, building a digital FM transmitter can be a challenging project for electronics enthusiasts. The transmitter can then be connected to a source of audio, such as a phone or computer, to broadcast music or other audio content.
In this project, I have introduced a compact digital FM transmitter circuit that operates in the frequency range of 87MHz to 108MHz. The frequency can be adjusted using two tactile push-buttons, with a 0.1MHz step size. The heart of the circuit is an ATMega8 microcontroller, which communicates with a 0.96-inch SPI OLED display and the KT0803L FM transmitter chip via an I2C interface. You can directly connect a microphone or an AUX cable to the board to broadcast your desired sound, such as playing a piece of music from your cellphone, computer, … etc. After conducting some tests, it was found that the circuit operates quite stable, and the received sound is clear and sharp.
To design the schematic and PCB, I used Altium Designer 23 and shared the project with my friends to get their feedback and updates using Altium-365. The fast component search engine (Octopart) allowed me to quickly consider components’ information and also generate the BOM. To get high-quality fabricated boards, I sent the Gerber files to PCBWay. I am confident that utilizing this circuit will be an enjoyable and fulfilling experience for you.
لطفا آموزش ساختشو با LCD1602 هم بدید و برای kt0803l آیسی حافظه 24c02c بزارید
As usual, another nice circuit, this time I'm watching the video in 4K 😊
Thanks
Yay
Yep
سلام مهندس عزیز ما که به آلتیوم دیزاینر 365 دسترسی نداریم میدونین که..... نمیشه از جای دیگه ای شماتیک این مدار رو به ما هم بدین مقلا ار ایمیل ممنون از زحماتتون
check the article link in the RUclips video description. I expect you to write English and watch the video completely
Range of the FM transmitter?
around 50 meters, without an external amplifier
Thank you for your reply.
May I know the function of each components in the circuits? I'd like to pay for it, and if you're willing to send on gmail
You should not be hurried when you try to learn something, as I mentioned in the video, detailed info is available in the article. I explained everything, invest some time
even in the article there is an option to order it assembled
Cool!! Do you have a video about programming arduino? If not could you please make a video for us beginners hehe thanks so much in advanced
if you check the article, I have provided the complied HEX file which you can directly program the MCU without any coding. Just don't hurry and invest some time on both the video and article :-)
