Multiple One-Wire Touch Detector Circuits on Same Body Without LED Activation

The discussion centers on implementing multiple simple one-wire touch detector circuits on the same body without activating any LEDs when more than one device is touched simultaneously by the same person. The original circuit uses a metal plate as a touch sensor to activate an LED. The challenge is to prevent LED activation if multiple such devices are worn on the same body, while allowing normal operation if worn by different individuals. Proposed solutions include replicating the circuit for multiple inputs, using off-the-shelf capacitive touch sensors for improved performance, and employing a relay or microcontroller logic to disable other devices upon one being activated. Another suggestion involves integrating proximity detectors on each device to detect neighboring devices and disable LED activation accordingly. However, this approach has limitations, such as failing to detect devices on different limbs or different people in close proximity. The conversation highlights the complexity of designing a system that discriminates between multiple devices on the same body versus different users, suggesting that a microcontroller-based approach with logical control might be the most feasible solution.
