[vc_row][vc_column][vc_column_text]Motor Shield makes it easy to control two brushed DC motors with your Arduino-compatible board. It is also compatible with pcDuino. With the motor shield, we can use pcDuino to build robot.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/1″][vc_tour][vc_tab title=”Parts List” tab_id=”1395910208-1-86″][vc_column_text]1. 1 x Motor Shield

2. 2 x  DC motor with tires

3. 1 x 6V-15V battery

4.  If pcDuino1 is used,  please add one T-Board for pcDuino1. We don’t need T-board if pcDuino2 is used.
