The project builds a proximity sensor using the CSD user module in the CY8C21434 device. A loop of wire is used as a sensor and when a hand approaches the sensor, a speaker is activated with a 1.4KHz signal. The raw counts, baseline and the difference counts are monitored using a CY3240 USB-I2C bridge.
