Humidity and Temperature Sensor
This is my Honeywell HIH-6130 breakout board populated with components. I tested it and it works perfectly. I only made one, this is a composite photo to show the front and back.

Homemade Arduino
This is a fully Arduino-compatible setup based on the Arduino breadboard except with a USB to serial converter and an RS232 level shifter instead of the FTDI chip. I used the parallel cable I’d made previously to burn the bootloader, then I was able to program it and to communicate with it via USB. This was all done using the normal Arduino software on Linux.

My First Microcontroller

My First Microcontroller
I finally got round to trying my hand at microcontroller programming. Following this instructable it was dead easy. The main problem I ran up against was in the software. On Linux you need the ppdev module in order to have access to /dev/parports. In menuconfig it’s Device drivers -> Character devices -> Support for user-space parallel port device drivers. On Debian you need the following packages: avr-libc binutils-avr gcc-avr avrdude Your user also needs to be in the lp group for access to the parallel port.
