Wise time with Arduino: First release of the Wise Clock 3 software: [ via ] The routine work of porting the “Wise Clock 2″ code to the new “platform” (namely the new 3216 bicolor display) went well. Most of features worked right off the bat. Some coordinates had to be adjusted in order to center the text (time etc) on the larger display

The LED cube 4x4x4 has the atmega32 controller and uses POV multiplexing to switch the 64 LEDS. A total of 16 transistors are used to switch on the Led columns and then another total of 4 lines to switch on or off the ground layer. So a total of 16+4 = 20 lines are needed to make the LED cube 4x4x4 work.

This project describes how to measure temperature with Atmega8 and a thermistor and display it on a Nokia 3310 LCD. A thermistor is a device that changes its resistance with temperature. With a proper resistor divider network, the temperature can be measured by measuring the voltage across the thermistor
