RDA5807M FM radio module for Arduino

I was surprised with it's ability to receive FM radio broadcast without any problem in such a small module. The size is not bigger than a coin, really small. It may a bit difficult for wiring but it can be done. You can also add small power audio amplifier and use small speaker directly. Here is the module chip, small power amplifier in prototyping pcb.

Wiring

ANT ----> External antenna

R-OUT ----> R audio

L-OUT ----> L audio

GND <----> GND

VCC <----> 3.3v

SDA <----> A4(analog pin 4)

SCL <----> A5(analog pin 5)

Libraries

Download: https://github.com/mathertel/Radio , there are several example files you can use to test.

Sketch

Download sketch: https://github.com/satujamsaja/Arduino/tree/master/rda5807m. Use serial monitor to control the radio. See the code for list of command.

Good luck.

Arduino : Controlling PL9823-F8 RGB LED

I have great passion about electronics since I was in middle school then high school. With some of my school friend that has same passion in electronics, we built radio transmitter so we can communicate each other at anytime. It was so cool back then. Thats why I took study on electrical Engineering. Instead of working on Electrical engineering field, I end up become web programmer. Something I found interesting when i was in college. That's old story. But lately I get bored and try to get another hobby. I have many hobbies and creating electronics stuff is one of it. So I bought my self Arduino Uno and few electronic components to get started learning Arduino programming. So my first project is controlling RGB Led. Here what you need: Arduino Uno with usb data cable and Arduino IDE Install Adafruit Neopixel library 3 PL9823 RGB led Breadboard Jumper cables (mostly male to male) First you need to install Arduino IDE. You can download it here . That would depend

Using LCD 2004a I2C on project with Arduino

On previous post measurement sensor results displayed on serial monitor. This is good when we are on development stage. When we want something more independent we need external display. I have purchased a few type of display. For now we will use LCD 2004 for external display.
