Raspberry Pi Pico

The Raspberry Pi Pico Blocks

The blocks consist of a set of command blocks that are rectangular in shape and reporter blocks rounded in shape.

Command Blocks

Write Digital

This block allows you to select a pin and set its output to either a one or zero. It has two parameters. The first is a drop-down list of valid PINs. The second parameter is the output value. It also is a drop-down list and contains the values zero and one.

NOTE: Pin 25 controls the board LED.

Write PWM

This block allows you to select a pin and set its PWM output to be a value between 0 and 100%. It has two parameters. The first is a drop-down list of valid PINs. The second parameter allows you to fill in a PWM value. If you use a PWM value of less than zero, it will be set to 0 internally. If you set the value to greater than 100, it will be set to 100.

NOTE: Pin 25 controls the board LED.

Write Servo

This block allows you to control the angle of a servo motor. It contains two parameters. The first is a drop-down list of valid PINs. The second specifies the angle in degrees. The value is limited to be between 0 and 180.

Reporter Blocks

Read Digital

This block allows you to read the current state of a digital input pin. It has two parameters, a drop-down list containing all the valid GPIO pins and a parameter to enable or disable the pull-up resistor on the Pico GPIO pin. It reports the raw value of zero or one.

Read Analog

This block allows you to read the current state of an analog input pin identified by its ADC number.

ADC Number	GPIO Pin Number
0	26
1	27
2	28
3	Temperature Sensor

It has one parameter, a drop-down list containing all the ADC Pins. It reports a value between 0 and 4095.

Read Sonar

This block allows you to connect an HC-SR04 type device. It has two parameters, both containing a drop-down list of valid PINs. The first parameter allows you to select a trigger pin, and the second an echo pin. It returns the measured distance in centimeters.
