15 LED’s Arduino Bar-graph Display and AD22151 Magnetic Field Sensor

My experiment with AD22151 Magnetic field sensor and 15LED’s Arduino Bar-graph display, the project shows how to read an analog input on analog pin A1, and print it out to 15 Bar-Graph LED’s. Bar-Graph board is Arduino compatible and hold ATmega328 chip on board, 15 LED’s with 330 Ohms series resistors. Supply 5V DC.
