It has more or less the same functionality of the Arduino Duemilanove, but in a different bad credit engagement ring how to buy. This is a project which is based on the Arduino Nano and it's interfacing with other sensors. HC-SR04 or an ultra sonic sensor is a male device that works on the principle legel transmission and reflection.
The function of ECHO pin is to emit the waves to the channel. These waves travel through the medium as a wave and reflects back when ever it hits an object or an obstacle ahead of its propagation. The time taken taken for the emission and reflection is calculated and using this value we decide the distance of the lveel approaching us. I'm using an I2C driver this just to eliminate the messy and large number of jumper wire making a way to connect more sensors and output devices. Mqke brief description of the I2C pins are.
Data line Indicqtor : This line or the transmission line of the I2C is used to transmit data from transmitter to the receiver.
The character needed to be displayed lwvel the LCD are transmitted through this line. Clock line SCL : This is a control line of the I2C which decides the rate at which the characters are transmitted just like the clock pulse in traditional flip flops.
The code is quite simple and is quite similar to that as shown in the step 3 of this project, in addition we are now adding some more libraries to get the I2C LCD working. You can download the libraries form here. Make sure you have entered the right I2C address in the code, the default address of the I2C is levsl. Copy and paste the below code into the arduino IDE and select the arduino nano and the right port and then hit upload. And after you have completed the project you should indciator the arduino display tp water level ti the LCD.
You can an additional buzzer to let you know then the the water level reaches after certain threshold. Question 9 months ago. How to install the I2C library? Tip 11 months ago on Step 4.

Learn more Making your own water level indicator is a fun school science project or if you just want a simple indicator for your home water tank.
These devices signal when water reaches a particular point, which means that you know when the water is about to overflow. Get all of the supplies that you need first such as LEDs, a buzzer, and sensing wires.
Then build the circuit and attach the battery. Watch the LEDs light up as the water level rises and listen for the buzzer when the level gets too high! Once you have your materials, start by removing the plastic coatings from the integrated circuit pins and cutting the sensing wires to the lengths of the water levels you want to measure. Complete the circuit by attaching the battery connector and 9-volt battery.
Things You'll Need. Related Articles. Article Summary. Part 1 of Get all of the electronic parts that you need for the project. A water level indicator requires a few different electronic components to create a circuit. These components are simple and easy to find. You can purchase all of the parts that you need either at an electronics supply store or online. This is a tiny set of premade electronic circuits that are mounted on a flat piece of silicon.
The length doesn't matter, as you will be cutting them to size later on. You can also solder sensing wires together if one is too short.
A 9-volt battery and a battery connector are required to provide energy to the water level indicator. Find all of the tools that you need to make the water level indicator. You only need a couple of tools to make the circuit for your water level indicator. These tools are easy to find and use, and you may even already have them at your school or home.
You can purchase any tools that you don't have from home improvement stores or online. A soldering iron and solder are key for most electronics projects. This is how you will connect the circuit together. You will also need wire cutters to cut the sensing wires to size. The leads on the IC in this project are pointed down to stick through holes in a circuit board. Use the pair of pliers to gently bend the IC leads up and out flat on both sides for easier soldering.
Cut the 5 sensing wires to the different lengths you want to measure. The length of the sensing wires that you need depends entirely on the different water levels that you are planning to measure.
Use the wire cutters to cut 2 long wires of equal length. Then cut the remaining 3 wires progressively shorter. For example, the 2 longest wires could be 10 in 25 cm each, and the remaining wires could be 8 in 20 cm , 6 in 15 cm , and 4 in 10 cm respectively. The other longest wire is for the buzzer, which signals when the water is at the highest level. Part 2 of Hold the LED negative point on the pin and feed the solder to the tip of the soldering iron where the LED negative point and the pin meets.
There are 8 pins on each side and a notch at one end of the IC. With the notch toward the top, pin 1 is next to the notch on the left side and pin 8 is at the bottom left side.
Pins 9 to 16 are counted up the opposite direction with pin 16 being next to the notch on the right side. Connect the positive point of the pin 12 LED to pin 9. Identify the LED that has its negative point attached to pin Use the soldering iron to solder the positive point of that LED to pin 9. Be very careful not to burn your fingers as you work in the tight space with the soldering iron.
Attach the buzzer's positive point to pin 10 and the negative point to pin It's now time to add the buzzer to your circuit! Use the soldering iron and solder to connect the buzzer's positive point to pin 10 first. Then attach the buzzer's negative point to pin Even though the buzzer isn't attached directly onto pin 12, it still works because the wires are connected in a circuit.
The negative point on the buzzer has a shorter lead than the positive point. This is the same as the LEDs. Use the soldering iron to connect all of the positive LED wires together. Solder the positive wires that stem from each LED together so that they all connect in a circuit. The positive point of the buzzer is already connected to the circuit. This completes the circuit which means that all of the LEDs will work when you use the water level indicator.
Attach the sensing wires to pins 1, 3, 5, 7, and 9. Begin working on the other side of the IC where you haven't soldered any wires yet. Solder the 2 longest wires to pins 1 and 9. Then solder the second longest wire to pin 3, the second shortest wire to pin 5, and the shortest wire to pin 7.
For the wire that attaches to pin 9, attach it between the buzzer and the IC pin. The buzzer will also indicate when the water level is high. Part 3 of Attach the battery connector's positive wire to pin 9 and the negative wire to pin 8. Follow the same process of soldering the wires to the wires that stem from the correct pins at the IC.
Let the battery connector rest to the side after it has been attached. It will be at the top of the water level indicator, at the same height as the buzzer. Connect the 9-volt battery to the water level indicator.
The hexagon shape on the battery indicates the negative terminal while the circular shape indicates the positive terminal. Press the hexagon terminal of the battery connector onto the circular terminal of the battery and vice versa. Make sure that the battery connector is securely attached to the battery. Test the water level indicator. Place the sensing wires of the water level indicator into a glass, cup, or container.
Slowly fill up the glass, cup, or container with water. Watch as the LED with the longest wire indicates when the water level is lowest and how as the water level rises, the LED with the shortest wire shows when the water is at the highest point.
Listen for the buzzer too when the water level reaches the highest point. Include your email address to get a message when this question is answered.
