Build a thermostat using Arduino Uno, LCD display, temperature sensor and few LED's. Write a program in Arduino IDE which will work for the heating and cooling process. Use the temperature sensor to measure the current temperature. Display the current temperature on the LCD display. You need to use a loop for comparison of current temperature with the set temperature. LCD display should display the current and set temperature. Try to implement red and green LED's for heater and cooler side respectively. Modify the project using the remote given in the kit. You should use the remote to change the temperature up and down the set temperature.

Speed control by DC motor-speed controller is required to realize variable speed drive. Whenever a motor drives a particular load, it is called drive, and variable speed drive refers to a load requiring variable speed. All this is obtained by a DC motor …
