In order to use this module, you will need to install drivers ( Windows driver, Mac driver, Linux is good out of the box).Īssemble the circuit onto the bread board, and please double-check all 5V and ground connections. We need this USB to FTDI adapter to program our ATmega chip from the Arduino IDE. The FTDI I like to use also does not have a library yet, but follow my photo for the wire colors and it will connect fine.
Using Fritzing I found a similar, though not the exact power supply make sure it it set to 5V top and bottom. The only changed a few things my resistor choice to the LED was 330-ohms and I added a variable resistor for the analog-read sketch, of its 3 legs, the outer ones go to 5V and ground, the center leg goes to port A0. Open Home Automation has a good blog on this (since I shamelessly borrowed his schematic, I will give due credit). Similar blogs can be found on the site, my own Breadboard Electronics site. The ATmega we know and love has been pre-programmed with a bootloader to talk to the Arduino IDE (integrated development environment) and is available for about $5 USD (See SparkFun) you can get it for about half that cost in bulk if you program your own bootloader ( has instructions). So, if you are designing your own circuit and spinning your own PCB, you might consider incorporating an Arduino within your design (it is open-source, after all). There is so much capability within the chip, the external parts count is low: each port can sink or source about 40mA it has a physical serial port, other dedicated ports can produce PWM (pulse-width modulation), and various serial protocols (i2c, SPI, 1W, 2W, etc.) and it has 6 A/D (analog to digital converter) ports.
Today, you run a 50/50 chance of finding an Arduino with an ATmega chip as an ARM processor emulating one. The ATmega (ATmega328P-PU) (and ATmega128) is THE CHIP that got everybody playing with microcontrollers via Arduino boards. USB type A plug to type mini-B plug cable
