Following AVR version, we present your with PIC version of Programmable relay timers project. We have created a demonstrational software for all of our PIC compilers and prepared a special project kit which you can use to build your own programmable relay timers under a minute. Just connect Ready for PIC, Keypad 4x4 board with EasyPull, RTC, Relay 4 and LCD 2x16 character display with adapter and load demonstration project code and your device is ready to rock! It can control 4 separate relays.

Video Demonstration of the project

Watch on YouTube

  1. Using “D” key on keypad 4x4 board you can scroll through settings for each relay. You can change the ON and OFF times by positioning the cursor to the desired location and changing time values as you desire. Navigation, or moving the cursor is done using asterisk (*) for backward and sharp (#) key for forward.
  2. Press “C” key to display current time.
  3. Press “B” key to enter the mode for adjusting the current time value. Position the cursor over the desired location and change HH:MM:SS values to synchronize it with your local time. After you are done, press “B” again to save the newly set value.

Applications

Project has numerous applications. We only suggest several:

  1. Controlling garden sprinklers
  2. Turning ON/OFF home appliances (Coffee makers, toasters, TV sets, airconditioning, old washing mashines, etc.)
  3. Programming city or home fountains to turn on and off in the same time of the day
  4. Controling street lamps and home lights

We are sure that you will find much more possible applications. Don’t hesitate to send us photos of what you have built using this project kit.

Source code of this project is provided for free, so you can modify it to suit your needs. Since PIC18F45K22 comes preprogrammed with free UART Bootloader, you won’t have to spend a dollar more on external programmers. You can modify the project as much as you like, and expand this basic functionality with your own implementation ideas.

EERAM 5V Click

0

EERAM 5V Click is a static RAM (SRAM) memory Click board™ with the unique feature - it has a backup non-volatile memory array, used to store the data from the SRAM array. Since the SRAM is not able to maintain its content after the power loss, the non-volatile EEPROM backup can be a very handy addition that can be used to preserve the data, even after the power loss event. This is a very useful feature when working with critical or sensitive applications. The memory backup procedure can be executed both automatically and manually. When it is set to work in the manual mode, the onboard capacitor will act as a power source with enough power to complete the backup cycle. The power-on backup restore mode is also available, taking only about 25ms to complete.
