KS0083 keyestudio New sensor kit with Uno

Sensor kit for Arduino,Based on open-source hardware,30 various sensors in one box,for you to make interesting projects.

1.1 Introduction

This is an Arduino sensor learning kit developed by Keyes. We bring together 30 basic sensors and modules, aiming for the convenience of its learning for starters. Inside this box, there are digital and analog sensors and also some special modules such as buzzer, ultrasonic, acceleration modules etc. For each module, there is clear connection diagram and sample code. So even if you are totally new at this, you can get started easily.

The sample codes for this sensor kit are based on ARDUINO because it’s open source and easy. And if you are good at this, you can also apply this kit to other MCU development platform, such as 51, STM32, Raspberries Pi. The working principle is pretty much the same.

Now, let us embrace this fascinating world of ARDUINO and learn together!

1.3 The Keyestudio REV4 (Black) Main Control Board

The Keyestudio REV4 (Black) Main Control Board is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the Keyestudio REV4 (Black) Main Control Board is the most robust board you can start playing with.

Here is an explanation of what every element and interface of the board does:

No.

Explain

ICSP（In-Circuit Serial Programming) Header
In most case, ICSP is the AVR, an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND. It is often called the SPI (serial peripheral interface) and can be considered an “extension” of the output. In fact, slave the output devices under the SPI bus host. When connecting to PC, program the firmware to ATMEGA328P-PU.

Power LED Indicator
Powering the Arduino, LED on means that your circuit board is correctly powered on. If LED is off, connection is wrong.

Digital I/O
Keyestudio REV4 (Black) Main Control Board has 14 digital input/output pins (of which 6 can be used as PWM outputs). These pins can be configured as digital input pin to read the logic value (0 or 1). Or used as digital output pin to drive different modules like LED, relay, etc. The pin labeled “〜” can be used to generate PWM.

GND(Ground pin headers)
Used for circuit ground

AREF
Reference voltage (0-5V) for analog inputs. Used with analogReference().

SDA
IIC communication pin

SCL
IIC communication pin

ICSP(In-Circuit Serial Programming) Header
In most case, ICSP is the AVR, an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND. Connected to ATMEGA 16U2-MU. When connecting to PC, program the firmware to ATMEGA 16U2-MU.

RESET Button
You can reset your Keyestudio REV4 (Black) Main Control Board, for example, start the program from the initial status. You can use the RESET button.

D13 LED
There is a built-in LED driven by digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it’s off.

USB Connection
Keyestudio REV4 (Black) Main Control Board can be powered via USB connector. All you needed to do is connecting the USB port to PC using a USB cable.

ATMEGA 16U2-MU
USB to serial chip, can convert the USB signal into serial port signal.

TX LED
Onboard you can find the label: TX (transmit).When Keyestudio REV4 (Black) Main Control Board communicates via serial port, send the message, TX led flashes.

RX LED
Onboard you can find the label: RX(receive ).When Keyestudio REV4 (Black) Main Control Board communicates via serial port, receive the message, RX led flashes.

Crystal Oscillator
How does Arduino calculate time? by using a crystal oscillator.The number printed on the top of the Arduino crystal is 16.000H9H. It tells us that the frequency is 16,000,000 Hertz or 16MHz.

Voltage Regulator
Convert an external input DC7-12V voltage into DC 5V, then switch DC 5V to the processor and other components. Output DC 5V, the drive current is 2A

DC Power Jack
Keyestudio REV4 (Black) Main Control Board can be supplied with an external power DC7-12V from the DC power jack.

IOREF
Used to configure the operating voltage of microcontrollers. Use it less.

RESET Header
Connect an external button to reset the board. The function is the same as reset button (labeled 9)

Power Pin 3V3
A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.

Power Pin 5V
Provides 5V output voltage

Vin
You can supply an external power input DC7-12V through this pin to Keyestudio REV4 (Black) Main Control Board.

Analog Pins
Keyestudio REV4 (Black) Main Control Board has 6 analog inputs, labeled A0 through A5. These pins can read the signal from analog sensors (such as humidity sensor or temperature sensor), and convert it into the digital value that can read by microcontrollers).Can also used as digital pins, A0=D14, A1=D15, A2=D16, A3=D17, A4=D18, A5=D19.

Microcontroller
Each Keyestudio REV4 (Black) Main Control Board has its own microcontroller. You can regard it as the brain of your board.
The main IC (integrated circuit) on the Arduino is slightly different from the panel pair. Microcontrollers are usually from ATMEL. Before you load a new program on the Arduino IDE, you must know what IC is on your board. This information can be checked at the top of IC.

1.4 Keyestudio Sensor Shield V5

1.Introduction

In the experiments, you might often use REV4 control board and several sensor modules. If the interfaces of power output is not enough, you may need to add a breadboard and use many connection wires. Is it really troublesome？

But now, with this keyestudio sensor shield, you can easily solve that problem. This shield is fully compatible with REV4 control board, so you can easily stack it onto REV4 for use.

This keyestudio sensor shield has extended the digital and analog ports out as 3PIN interface (G,V, S), which can directly connect 3PIN sensor modules.

It also breaks out some communication pins of 2.54mm pitch, like serial, IIC, and SPI communication.

The shield comes with a reset button and 2 signal indicators as well.

Additionally, you can supply the voltage needed to the sensor modules through blue terminal blocks on the shield. Because some sensor modules is not used with 5V or 3.3V but with special voltage.
