Smart shirt circuit

The whole smart shirt electrical circuit is designed mainly considering multiconnection of ultrasonic sensors as discussed in Section 3.3.1.4. Therefore, the schematic circuit concept of vibration motors, ultrasonic sensor, and microcontroller will first be introduced and then the schematic diagram of the whole smart shirt circuit will be given in detail. 

The LilyPad Arduino microcontroller board is used. The LUyPad Arduino has a circle shape, approximately 50 mm in diameter. The thickness of the board itself is 0.8 mm, and with the attached electronics it is approximately 3 mm. The LilyPad Arduino can be powered via USB connection or with an external power supply. In smart shirt circuit design, it is powered with a 4.8 V NiMH flat battery. The board is based on ATmega328 [8]. The schematic diagram of the board is shown in Fig. 3.7.
