1 instructables Arduino Mini Shields Construction by Patel Darshil Presented Here are the Arduino Mini Shields. These Shields are very easy and fun to make. Arduino shields are very useful for the Arduino to help you out in some very common projects like IR Communication, Relay Controlling, etc. This shields are also portable. You can also make your own custom Mini Arduino Shields. It is a Great IOT Project to make. In this project, I experienced that Each Shield is like a mini electronic Project. And I think it would be nice project for Beginners in Arduino. I first of all Made the Relay Shield. I started making week ago and one by one I completed all six of them. Now, I have presented here Six Arduino Shields. 1. IR Communication Shield 3. Light Sensing Shield 4. D-Pad Shield 5. Seven Segment Display Shield 6. Relay Shield. I have also provided codes for testing your mini shields and to show that all shields are fully functional. you can also make a Custom Shield of Mini Shields I am sure you would find the instructable Interesting. PLEASE DO NOT FORGET TO FAVORITE AND VOTE THIS INSTRUCTABLE!!! 2. Debouncing A Button Shield Arduino Mini Shields Construction: Page 1

3 Step 1: Arduino Pin Configuration Above image shows you some pin configuration which ais very useful for making arduino shields and connecting them at right place for perfect working. Arduino Mini Shields Construction: Page 3

4 Step 2: Components for Debouncing a Button Shield Here are the list of Components for Debouncing A Button Shield: ohm Resistor 2. LED 3. 10k Resistor 4. 4 pin Connector Tactile Switch 2. Tactile Switch 3. 4 pin Connector ohm Resistor 5. 10k Resistor 6. LED Arduino Mini Shields Construction: Page 4

5 Step 3: Debouncing a Button Here is the making of the Shield "Debouncing A Button". Sometimes we press a button but it does not count in the counter. Even if you press 10 times, it can count only to 5 or 6 times. In bouncing, the contact of the switch is made only one side and not both the side and then it contacts both the side. We will study the bouncing phenomena with the help of this shield and the code provided in the next step. Circuit Diagram is also provided in the images. In the circuit we have a tactile switch connected across pin no. 2 of Arduino UNO and VCC. 10k Resistor is placed across GND and Pin no. 2 of Arduino. 220 ohm resistor is connected to pin no. 13 and it is connected to positive terminal of the LED and negative terminal of the LED is connected to GND. So, there we have a complete Debouncing A Button Shield. Now, connect the shield to Arduino and apply the code from the next step. Press the button couple of times to see how it responds..
