![]() ![]() This means we can connect up to 8 analog input sensors to the board. The board consists of 8 analog input pins numbered from A0 to A7 while the analog output can only be achieved using PWM pins. We can generate the PWM signal using the analogWrite() function in the program. ![]() Every one of these digital pins can generate a Pulse Width Modulation signal of 2 3-bit resolution. PWM Pins:Īll the digital pins on Arduino Nano 33 BLE sense are PWM (Pulse Width Modulation) enabled pins that are numbered from D0 to D13. This kind of input is usually called digital (or binary) and these states are referred to as HIGH and LOW or 1 and 0. ![]() The Arduino digital pins can read only two states: when there is a voltage signal and when there is no signal. It is also called the primary voltage for IC’s present on the Arduino board. It is the modulated DC supply voltage, which is used to regulate the IC’s used in the connection. ![]()
