- Talking Thermometer for the Visually Impaired (LPC2138 ARM7TDMI)
Dhananjay Gadre and Divya Sardana
The efficient Talking Thermometer is designed around a Keil MCB2130 evaluation board. A temperature sensor measures the temperature, which is then announced through a unique audio system. Voice samples of numbers and words are stored in the on-board LPC2138 microcontroller’s memory. The MCB2130’s on-board audio amplifier and speaker and an external RC filter comprise the audio system.
