ARDUINO BASED DC MOTOR SPEED CONTROLLER WITH 16X2 LCD DISPLAY HD

The DC motor controller has been designed using multi LCD Arduino Nano shield, circuit, PCB and code available at our website www.twovolt.com , it can control DC motor 7-12V DC , current load up to 5amps. Speed of motor can be set using trimmer potentiometer, and LCD display shows the Bar-Graph of speed. Potentiometer is connected to Analog Pin A0 and Digital pin 9 is PWM out goes to gate of Mosfet. Compact multipurpose Arduino Nano 16X2 LCD shield can be used to develop various projects, shield provided with various things, LM 35 Temperature sensor, 3X Tactile Switch, Vertical trimmer potentiometer, 12V Relay with NO/NC output, power Mosfet, AC714 current sensor and 16X2 LCD.
