Arduino Servo Control

In this Project, we want to control servo motor potitions from analog sensor ( potentiometer or flex sensor ).

The Hardware

Write from Arduino to LCD

 Scheme Description:

• Connect the LCD RS pin to the Arduino pin 12
• Connect the LCD enable pin to the Arduino pin 11 
• Connect the LCD D4 to D7 pins into pin 5 to 2 Arduino
• Connect the LCD +5 and ground to pin +5 V and ground Arduino
• Connect the pin to a potentiometer LCD Vo. Use of this potentiometer is to adjust the LCD contrast

Temperature Sensor Using Arduino and LM35

LM35 is a temperature sensor from National Semiconductor that have a high accuracy. The output of analog voltage and has a measurement range of -55 º C to +150 º C with an accuracy of ± 0.5 º C. Output voltage is 10mV / º C. Output ports can be directly connected to Arduino, because Arduino has 6 ADC ports (analog input).
