This project gives you a simple temperature controlled fan. If the difference between real temperature and the user temperature is high then the fan will run at full speed and if the difference is low then the fan will rotate at slow speed. The speed of the fan varies with the temperature. The user can […]

There are lot of temperature sensors both with analog & digital outputs. This project gives you an another temperature indicator which has been done with a digital sensor SMT160. Although it is a digital sensor it does not gives out the temperature directly. The output is duty cycled modulated. The sensor can measure temperature from

With this project you can control a unipolar stepper motor. You can control both the speed and the direction of the motor. The speed and direction and can changed with help of the keypad. The data’s are displayed over the LCD display. A 4×4 keypad is used for entering the speed and selecting the direction.

Instructables author extraordinaire Randofo created a great programming shield to use your Arduino to program 8 pin ATTINY processors. He was even generous enough to give 50 copies of it out to people who authored instructables using AVR processors. It works great on brand new ATTINYs and any chip that is programmed to use it’s Internal clock.

Update May 4 2012: I am still working very hard on version 3 of Picopter. The new version’s hardware is already done. There are new 3D printed motor holders. I’ve done some measurements with regards to mass and radio spectrum. I’ve posted stuff to http://www.frank-zhao.com/picopter_forum/index.php including the new design files, so take a look. Update Feb

This project will display the temperature and time over the LCD display. LM35 is used to sense the temperature and the analog out of the LM35 is converted to digital by using the inbuilt ADC on the ATmega16 chip. An software clock is generated and the Time is also display. Download the Bascom code and
