Description This small thermometer board uses the Microchip TCN75 device. It is a cheaper clone of the LM75, it costs about 2,50 Euro. The TCN75 comes in a SO8 packaging. The TCN75 is a serially programmable temperature sensor. It has an output that is programmable as either a simple comparator for thermostat operation or as […]
Description This small thermometer board can be connected directly to PORTD of the AVR 2313 Project board. It uses the Dallas DS1621 Digital Thermometer and Thermostat chip. The DS1621 measures temperatures from -55° to +125° in 0.5° steps and doesn’t need calibration or external components. It has also a build-in thermostat with high and low
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.
This light helps your plants grow. I got the idea from the Garduino, but nothing is taken from it. The schematic and the program are mine. This plant light gives your plants 4 additional hours of light per day. When it gets dark, it turns on and after 4 hours of darkness, the light turns

Unless you’ve been living under a digital rock for the last few years, or just simply aren’t interested in flashing lights, you’ll already know about the awesomeness that is the BlinkM from ThingM. It’s a very small PCB featuring a high power LED that responds very easily and cleanly to commands you give it. Devices like BlinkM’s

In this Instructable, I cover modding the store-bought Deluxe Identity Disc to an upgraded version with 64 leds, controlled by an AVR MCU. The upgraded version is costume-ready and would be an excellent addition to your Tron costume – it’ll also look great on your desk/dresser/etc. My 7 year old daughter watched Tron:Legacy with me
