“The talking multimeter uses the PIC32MX250F128B as a voltmeter, ohmeter, and capacitance meter that speaks the reading as it is measured. Spoken measurements improve the usability of measurement devices since the user will be able to focus on the circuit in question and still obtain measurements. The speaking measurement system will provides an auditory alternative to a visual meter. Our system consists of a TFT LCD to display the reading, a keypad to read user input about the mode of the system, and speakers to hear the readings of both the keypad and the measurements. Key presses on the keyboard determine if the multimeter is used a voltmeter, an ohmeter, or a capacitance meter. Additional circuitry and the functionality on the PIC32MX250F128B is used to map the voltages to ranges acceptable for the MCU and to calculate the parameter values. Capacitance values can be measured between 1pF and 100nF. Resistance values can be measured between 0 and 50kΩ. Voltage values can be measured up to 10V and mapped down appropriately for the MCU using a voltage divider.”
