These are the directions to building the Chanel Blue prototype.
Section 1: Arduino
x1 Arduino Uno
x1 water sensor
x1 Bluetooth module
and a bundle of the little jumper cables (female - male)
Step 1: Connecting Water Sensor to the Arduino
First, we will be connecting the water sensor to the Arduino. Connect 3 jumper cables (of any desired colour, or length) to the prongs on the sensor that are labeled " S, +, -"
On one of the sides of the Arduino, we can see a side labeled "POWER" and "ANALOG IN". we will connect the jumper cables on this side of the Arduino.
" S, +, -" will go respectively to the sections labeled "5V, A0, GND" (s to 5v, + to a0, and - to gnd) like shown in the pictures.
Step 2: Connecting the Bluetooth Module to the Arduino
To proceed, we will now connect the Bluetooth module. If we take a look at the back side of the module, we can see the labels "STATE, RXD, TXD, GND, VCC, EN". Connect jumper cables to all the prongs except the first and the last one "STATE & EN".
In the Arduino, the area labeled "POWER" the cable labeled "VCC" will go into the section labeled "3.3V" (right next to "5V")
On the other side of the Arduino, the remaining 3 cables will be connected to the area labeled "DIGITAL". "STATE, RXD, TXD, GND" will go respectively with the sections labeled "1<-TX, 0->RX, & GND " (use the picture for reference)
Step 3: Section 2: Building the Power Circuit
Section 2: power
Another bundle of little jumper cables (male - female)
x1 lithium battery
x1 power shield
x1 USB B cable
x1 little blue switch
x1 wires with alligator clips
x1 USB female
x1 USB female with little LEDs
x1 regular USB cable
x1 little solar panel
Step 4: Connecting the Battery
On the power shield (that little blue square) there are to sections labeled "BATT" & "LOAD". Connect the lithium battery into the section labeled "BATT". (as seen in the pictures above)
Step 5: Completing the Circuit Pt.1 (USB Female)
Get your cables with alligator clips and another one of the black/white little cables. Get your USB female with LEDs (the one shown in the picture above) as well as the USB b cable
connect an alligator clip to the red end of the little cable.
The USB female has two little metallic plates in the front. Connect the other end of the alligator clip to the right metallic plate (as seen above).
Connect an alligator clip on the little metallic plate on the left (shown as green in the picture).
And lastly, connect the USB b cable into the USB female with LEDs.
Step 6: Completing the Circuit Pt.2 (little Blue Switch)
Take out the little blue switch, as well as more alligator clips.
connect an alligator clip to the end of the cable that is connected with the USB's left metallic plate. (shown as black in the picture above)
connect the other end of the clip into the switch (out of the 3 little things that protrude from the switch, connect the clip to either one at the end, but not the middle)
connect another alligator clip to the switch, but this time it must be connected to the one at the middle. (make sure that the clips don't touch directly!)
connect the other end of this clip into the little red wire (as shown in the picture above.)
Connect the wire to the power shield in the section labeled "LOAD"
Now you have completed this part of the circuit.
Step 7: Connecting the Solar Panel
Take out your solar panel, the USB cable, and the USB female (the one with the blue and black ends).
Connect the USB cable to the power shield.
Connect the USB female to the other end of the USB cable.
The solar panel has two wires coming from it, connected the black cable with the blue end of the USB female and the red cable to the red end of the USB female. (as shown in the picture above.)
we are almost there!
Step 8: Final Step: Connecting the Circuit to the Arduino
Connect the other end of the USB b cable into the Arduino (the one connected to the USB female with LEDs).
And we are now done! The final product should look like the one above.
