With this project, you will have at least four products in one because this kit consists of an Arduino Uno, an LCD Shield, a USB-A to USB-B cable, and all of materials that you will need to develop the following four projects: a Counter, a Thermometer, a Capacitor Meter and a 4-Channels Voltmeter. The first of them can be developed with the materials supplied while the rest of the meters will be a reality with the help of the appropriate Shield for each of them. That is, a 4-Digit Counter, a Thermometer based on LM35 sensor for measuring in both scales: Fahrenheit and Celsius, a Capacitor Meter with a scale from 100pF - 1uF, and finally a 4-Channels Voltmeter for measuring respectively in each channel a voltage from 0V - 50V.
What You Will Need:
Soldering iron and solder
Wire Cutter
Nose pliers
1 meter, 22 AWG wire
1 Arduino Uno R3 DIP Edition (Revision 3)
1 CABLE,USB2.0,A/B,6 FEET,BLACK,USB-A MALE TO USB-B MALE
1 DFRobot LCD Shield for Arduino
1 Resistor of 220 Ω, 1/4 Watt
1 Resistor of 10 MΩ, 1/4 Watt
4 Resistors of 1 MΩ, 1/4 Watt
4 Resistors of 100 KΩ, 1/4 Watt
3 Arduino Uno Proto Shield (PCB only)
3 Pass-Through Female Headers for Arduino Shields - 1x8 and 1x6 Position (2 each)
1 Temperature Sensor LM35
1 Alligator Clip Test Leads - 2 Pack Red and Black
1 16 AWG Alligator Clip Test Leads - 2 Sets of 5 Colors (10pk)
In this step, you are going to match the Pass-Through Female Headers and their corresponding pins with the PCB. Note that´s imperative that the photo in his step be observed so that you can insert the pins correctly. That is, you should insert the two 1x6 Pass-Through Female Headers in the side of the Analog holes beginning with the Analog holes and then the near six holes. Next, insert the two 1x8 Pass-Through Female Headers in the side of the Digital holes beginning with the Digital holes: D8, D9, ......... and then D7, D6, ........
For completing the shield, follow the instructions in the previous step. That is, connect one of the ends of each resistor to A1 where you will also draw the positive terminal of probe of this shield. Now, connect the remaining terminal of the resistor of 10MΩ to D2 while the remaining lead of the resistor of 220Ω to D3. Finally, draw the negative terminal of probe from GND. Remembering that you can cut the alligator clips at the measure of length what you wish.
For installing the resistors, connect an end of the resistor of 10MΩ to an end of the resistor of 100KΩ leaving free the other terminals of each resistor and so form 4 sets. That is, 4 common point between the resistors where you will also connect respectively to A2, A3, A4, and A5 being these the connections to your Arduino board.
The terminals that leave free of those resistors of 1MΩ connect them to red, white, yellow, and green alligators being these the voltages: Vr(0V-50V), Vw(0V-50V), Vy(0V-50V), and Vg(0V-50V) while the others corresponding leads of the resistors are those connected to A2, A3, A4, and A5 respectively. Note that you can cut the color alligator clips at the measure of length what you want.
