This product is an open-system design, which does not include a shielded enclosure, so it may cause interference with other electrical or electronic devices in close proximity. In a domestic environment, this product may cause radio interference.
- Page 5 General Safety Instructions ESD Protection ESD can damage boards and associated components. Cypress recommends that you perform procedures only at an ESD workstation. If an ESD workstation is not available, use appropriate ESD protection by wearing an antistatic wrist strap attached to the chassis ground (any unpainted metal surface) on the board when handling these parts.

Page 8: Hardware Requirements
You can configure each Component in the rich, mixed-signal Cypress Component Catalog with the Component Customizer tool. These Components include a full set of dynamically generated API libraries. After you have configured the PSoC system, you can write, compile, and debug the firmware within PSoC Creator, or export the firmware to other IDEs such as those from IAR, Keil, and Eclipse. -

Page 13: Theory Of Operation
Kit Hardware 2.2 Theory of Operation This section provides a high-level description of the principle of proximity sensing and describes where the CY8CKIT-024 kit and PSoC devices fit in a capacitive proximity-sensing system. 2.2.1 Principle of Capacitive Proximity Sensing Capacitive proximity sensors are conductive (usually copper/indium tin oxide) pads or traces laid on a nonconductive material like PCB or glass. -

These sensors can be interfaced with PSoC 4 devices present on Cypress PSoC Pioneer Kits through Arduino-compatible headers, as Figure 2-6 shows. - Page 15 Kit Hardware Figure 2-7: Sensor Pattern GND/SHIELD PROX 2.3.1.1 Proximity Sensors PS1 and PS2 Proximity sensors PS1 and PS2 are provided to detect horizontal gestures, such as hand movements, from left to right or right to left. Figure 2-8 shows a left-to-right hand movement. A gesture is detected based on the sequence in which these sensors detect the presence of a hand.

Page 16: Arduino-Compatible Headers
Kit Hardware 2.3.1.2 Proximity Sensors PS3 and PS4 The proximity sensors PS3 and PS4 are provided to detect vertical gestures, such as hand movements, from top to bottom or from bottom to top. Figure 2-9 shows a bottom-to-top hand movement. A gesture is detected based on the sequence in which these sensors detect the presence of a hand. - Page 17 Kit Hardware Table 2-2: J2 Arduino Header Pin No. Arduino Board Signal CY8CKIT-024 CY8CKIT-040 CY8CKIT-042 J2.1 LED5 P0.0 P2.0 J2.2 P0.1 P2.1 TANK J2.3 P0.2 P2.2 CY8CKIT-040 J2.4 P0.4 P2.3 J2.5 P1.3 P2.4 J2.6 P1.2 P2.5 Table 2-3: J3 Arduino Header Pin No.
