Time and Temperature for college physics laboratory experiment
TT4Lab (time and temperature for the physics laboratory) is a budget price chronometer and thermometer based on the Arduino UNO R3 microcontroller with two photoresistors PDV-P8001 (Advanced Photonics), one digital temperature sensor DS18B20 (Dallas) and the LCD keypad 1602 display (SaintSmart). TT4Lab enables many groups of students within a class to perform independent measurements and the firmware can be reprogrammed also by the students to adapt to the specific needs of various experiences .
