Coming from the Arduino world, most everything I do is 5v logic. It's been a switch for me now that I'm integrating my Raspberry Pi's into my Arduino solutions (they really are complementary). We have been following a great guy by the name of jean-damien, who has a simple solution to this problem: http://arduinotronics.blogspot.com/2014/10/making-raspberry-pi-talk-5v.html

Arduino Himalayan Salt Candle
Himalayan Salt Lights are really cool looking translucent salt "Rocks". With a lightbulb inside, not only are they a soothing warm light, but they are supposed to give off Negative Ions that leave you refreshed. I have added a Arduino and  SSR to give my li...

The Under $5 Arduino
Next time you build a permanent project, don't waste a $15-$30 Arduino board. You can get the same functionality of the Arduino UNO for less than $5 at http://goo.gl/ZhOrrh No usb or power onboard (requires 5v). Program it with an existing UNO or a FTDI Cab...

4 Channel 16 Bit ADC Arduino / Raspberry Pi
The Arduino UNO has five 10 bit Analog to Digital Converter pins (0-1023), but I needed higher resolution. I'm working with a I2C connected 16 bit 4 channel ADC from Adafruit called the ADS1115 . 16 bits of resolution allows me to measure signed integers wi...

De-Soldering Can Be A Pain!
I typically hate de-soldering. Removing old parts, or re-working a new design can be tricky, as you can over heat a part, damage the board, etc. Well, I've been using a inexpensive manual pump tool for months now, and it works GREAT! Cleans the holes out we...
I typically hate de-soldering. Removing old parts, or re-working a new design can be tricky, as you can over heat a part, damage the board, etc. Well, I've been using a inexpensive manual pump tool for months now, and it works GREAT! Cleans the holes out well, and the parts drop right out.

Nicely done. Even have the colors on the resistor and the polarity on the LED.

Read 4 separate voltage inputs, or 2 differential inputs.

Have two separately configured RFID readers one one Arduino.
I have an application that needs two RFID readers. Because these RFID readers are SPI devices, they can be connected to the same two data pins (MISO & MOSI), and clock pin (SCK), and only two pins (SDA & RST) have to be unique. This makes a total of 7 data pins, plus 3.3v and Gnd. I'm taking the ...
