In the above diagram you would read an analogue value physically from: the 4thpin up on the left. Warning:A4 and A5 are shared with I2C. About I2C One thing you have to be aware of is that when you use the I2C module, pins A4 and A5 are used as the data (SDA) and clock (SCL...
The libraries attached have been enhanced to give a much faster performance on an UNO using direct port access, other boards could be used by commenting out a #define and changing the the SPI pins. The UNO is connected to the ILI9241 2.2" TFT display like this: UNO +5V to display pin ...
Then all you do is read the analogue values using an Arduino using the Arduino adc.You can buy an Arduino joystick module as shown below - these have the power pins and two analogue outputs, but the also have a push button pin that activates when you push the joystick down....
Pin 9 is used by the TMRpcm library for playing back tones, so this interrupts our sequential 2-9 keypad pin layout. Also pins 10-13 are being used by the SD card shield which leaves us with no extra pins to finish our button and last keypad pins on the right side of the board. N...
You want to talk serial to another peripheral (like an RFID Module) AND watch the action in the Serial Monitor at the same time, so you need more UARTS. You want to use SPI and control a motor and read a few sensors, and pretty soon you’re out of pins, so you need more I/O ...
Analogue InputA potentiometer sets the temperature that the alarm will trigger at.This is read while in "Temp Set" mode, but is ignored at other times.DS18B20This is a Dallas "One Wire" device that communicates with the micro to provide temper...
My project is a data loger where three analogue inputs are sampled each time a rotary encoder pulse steps clockwise. On an Arduino, time is of the essence to get this data sampled and saved somewhere (I have not included the ‘saving somewhere’ part of this project yet.) (译者大体意思...
This shield has extended all the digital and analogue pins out into 3PIN, making it easy to connect to sensors using 3PIN wire. A switch is provided to switch on/off the HM-10 BLE 4.0 module, and 2 jumpers allow to select D0 and D1 or D2 and D3 as serial communication port....

Analogue inputsThe Arduino Uno has six analogue inputs which you can access on digital pins 0 (A0) to 5 (A5). They have 10-bit precision.Analog referenceYou can use analogreference to set the reference voltage for the analogue inputs:...
