Raspberry Pi and Arduino: Serial Communication Over GPIO pins - Just Push Buttons

Raspberry Pi and Arduino: Serial Communication Over GPIO pins - Just Push Buttons | Arduino, Netduino, Rasperry Pi! | Scoop.it

I recently received a Raspberry Pi from a friend and I wanted to see if I could tie it to one of my Arduino boards without using a USB cable. The tutorials I found were helpful and relatively simple but were missing some details that I thought would be helpful. So I’ve decided to make a (hopefully) more simple tutorial to get people up and running with serial on the Raspberry Pi’s GPIO pins.

» What if the supply is under 3.3V? JeeLabs | Arduino, Netduino, Rasperry Pi! | Scoop.it

The standard Arduino Uno, and all models before it, have always operated the ATmega at 5.0V – which used to be the standard TTL levels used in the 7400 series of chips used in the 1960′s and 1970′s...


Nowadays, chips operate at lower voltages because it leads to lower power consumption and because it is a better fit for batteries and LiPo cells. In fact, lots of new chips operate at 3.3V and will not even tolerate 5.0V.

Experimentation - Arduino for All: On the move | Arduino, Netduino, Rasperry Pi! | Scoop.it

In the last article I talked about programming the Arduino so it could be used to receive GPS signals and display them on the monitor screen, which is all well and good. But of course we want to do a bit more; expand our abilities. So, what can we do? Well, we can attach a data-logger which will allow us to (you guessed it) log the GPS information as we move around.

Turning the Raspberry Pi Into an FM Transmitter

 It uses the hardware on the raspberry pi that is actually meant to generate spread-spectrum clock signals on the GPIO pins to output FM Radio energy. This means that all you need to do to turn the Raspberry-Pi into a FM Transmitter is to plug in a wire as the antenna (as little as 20cm will do) into GPIO pin 4 and run the code posted below. It transmits on 100.0 MHz.

Dr. Monk's DIY Electronics Blog: TEA5767 FM Radio Breakout Board for Arduino

Dr. Monk's DIY Electronics Blog: TEA5767 FM Radio Breakout Board for Arduino | Arduino, Netduino, Rasperry Pi! | Scoop.it

I recently failed to resist buying two TEA5767 FM Radio modules from eBay for almost nothing. These little modules use the I2C serial protocol and so are ideal for connecting to an Arduino.


These things are tiny. This image is much larger than the real thing. In fact, the connectors on the side are at a smaller pitch than the 0.1 inch found on the Arduino connectors. So, the first just was to make a little breakout connector using a bit of stripboard.

My Raspberry Pi as a True Random Number Generator : raspberry_pi | Arduino, Netduino, Rasperry Pi! | Scoop.it

I thought i would share with you my latest project involving the raspberry pi. I decided to make a random number generator using the static from an untuned TV.

 

Basically i setup the raspberry pi with a webcam and pointed it as the static on the TV. I used a python script to take a picture every couple of seconds. It then converted the picture it took into a black/white image.

Gregory Crawford's insight:

An interesting discussion on using static noise from an untuned tv channel as a source for a random number generator.
