Arduino FM Radio project with a Nokia 5110 display and TEA5767 module.

Welcome to the Arduino FM radio project update video! We are using a Nokia 5110 LCD display and a rotary encoder! Subscribe for weekly videos ▶ https://bit.ly/33KIQ09 I have built a new, improved version of the FM radio project, which resolves the issues we had in the previous version of the project. The sound quality the project now offers is much better, and it has some new features as well. But first, let's hear it play a YouTube safe song I am broadcasting using this small FM transmitter. The sound quality is very good in my opinion if we take into consideration that we are using a very inexpensive speaker and amplifier. I replaced the LM386 amplifier module with the PAM8403, and I noticed a huge improvement in the sound quality. The amplifier module offers an embedded potentiometer to control the sound output, so we need one part less. I also replaced the potentiometer I was using to change the frequency of the Radio receiver with a rotary encoder. This way, the frequency the radio receiver is set is stable, and we also gain a button. I am using the rotary encoder button to turn the backlight of the display on or off. Another feature I added is that if we leave the Radio Receiver at the same frequency for more than 5 minutes, it will automatically save that frequency to the Arduino EEPROM memory. So, the next time we power up the project, the radio will automatically tune in to the frequency we were listening before. Cool isn't it? 💻 Code & Parts: http://educ8s.tv/arduino-fm-radio-2 👨‍💻 Check my new YouTube channel: https://bit.ly/3tku2n0 🎮 My Android Game: http://bit.ly/QuizOfKnowledge
