Gomes, Victor V.; Cavaco, Sofia C. F.; Morgado, Carmen P.; Aires-de-Sousa, João; Fernandes, Julio C. B. – Journal of Chemical Education, 2020
This work describes a simple talking calorimeter for the visually impaired based on the Arduino Uno without any shield. An electronic interface was designed using a Wheatstone bridge, a thermistor, or an operational amplifier (opamp). The temperature values are communicated by a loudspeaker connected to pulse-width modulation (PWM) digital output…
