ATTiny85 8-bit AVR Microcontrollers Atmel Microchip Technology

there are some nice usb programmable attiny85 digispark prints out there for +/-1 euro
attiny85 5? in or out pins (6? but the reset pin is not so handy fused, and blocks reprogramming if used)?
nice for making your own
attiny85 dsb18b20 433mhz sender thermometer device
or
9v battery 7805 attiny85 i2c digital compass 433mhz sender and put it all on a wind_direction_vane sending the wind compass direction from the rotating vane

attiny85 chicken coop?





ATTiny85 8-bit AVR Microcontrollers Atmel Microchip Technology

Digispark USB Development Board
The Digispark is an Attiny85 based microcontroller development board similar to the Arduino line, only cheaper, smaller, and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE the Digispark is a great way to jump into electronics, or perfect for when an Arduino is too big or too much.

The Digispark is shipped fully assembled except for the two included and easy to solder headers.

Here are the specs:

Support for the Arduino IDE 1.0+ (OSX/Win/Linux)
Power via USB or External Source - 5v or 7-35v (12v or less recommended, automatic selection)
On-board 500ma 5V Regulator
Built-in USB
6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB)
8k Flash Memory (about 6k after bootloader)
I2C and SPI (vis USI)
PWM on 3 pins (more possible with Software PWM)
ADC on 4 pins
Power LED and Test/Status LED

attiny85 i2c oled display
Attiny85(micro usb)+OLED 128*64 Screen Display +DHT22(Temp and Humid)
-This project is reading temparature(C) and humidity
from a DHT22 to display on an OLED 128*64 pixel (0.96") that is processed by Attiny85 (micro usb).
Additinal uploading to attiny85 and driver(header file) OLED for only attiny85.



make your own 433mhz 866mhz wireless rf devices quite cheap with attiny85
a door status 433mhz sender only sending when open
now you can make your own doorsensor sending open and close signal,
and maybe repeat door status signal sending every ??? seconds

Attiny85 with DHT11 rf 433mhz weather station
I was working on RaspberryPi weather station and I want something feed the station in low power.
So I found really cheap low power Attiny85 and DHT11
