FAQ:

Q: What are the best Arduino boards?

A: The Arduino Uno is the most “standard” Arduino board currently on the market, and is probably the best choice for beginners just getting started with the platform. The board is compatible with more shields (add-on boards) than other models.

Q: What is the working principle of Arduino Uno?

A: The Arduino Uno is designed to sense the environment by receiving input signals through sensors and communicating with the environment via actuators.

Q: How to program Arduino Uno?

A: Select the board which you are using to program by going Tools > Board (In my case UNO). … Open the ArduinoISP code which ca be found by going to File > Examples > ArduinoISP. Upload the sketch. After Uploading the sketch,again go to Tools > Board and now select the board which is to be programmed (In my case NANO).

Q: How many bits can an Arduino Uno read?

A: Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage (5V or 3.3V) into integer values between 0 and 1023. On an Arduino UNO, for example, this yields a resolution between readings of: 5 volts / 1024 units or, 0.0049 volts (4.9 mV) per unit.
