This project describes how to use all the 8 ADC channels of an Atmega48 microcontroller to read temperature sensors and the measured data to a PC for logging by using the built-in USART capabilities of the chip. For demonstration, the temperature sensor used is LM335 that gives an output voltage proportional to the Kelvin temperature. […]

This is merely an instructable to explain how this device operates. I hope everything is not too obfuscated. This prototype consists of three 8×8” modules. Each module operates independently of each other. Each module consists of 4 “pixels”. Each pixel is 4 inches square and consists of 21 LEDs, two IR emitting diodes, and two
I really like nixie and numitron clocks, but I never worked with them before. So I decided to give it a go. I choose numitrons because of 2 reasons: first of all nixies need a higher voltage than numitrons to work. Nixies need around 170V DC and numitrons only 4,5V so they are safer to
