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.

Read temperature and barometric pressure from GY BMP 280 using Arduino

This sensor based on BMP 280 digital pressure sensor made by Bosch. You can find the complete datasheet here . This small sensor is quite impressive with it's accuracy. It claimed to be ±1 hPa in measuring barometric pressure, ±1.0°C in temperature measurement and ±1 meter in altitude accuracy. Pretty impressive right ?

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.
