In this video lesson we present the solution to the homework assignment given in LESSON #6. Your assignment was to create a dimmable LED where the brightness of the RGB LED is controlled by the potentiometer. We are still using the schematic from our earlier project.

Fusion Hat Circuit Diagram — This is the circuit we will use moving forward in the class

In this lesson, this is the code which we came up with:

#!/usr/bin/env python3
from fusion_hat.adc import ADC
from fusion_hat.pwm import PWM
from time import sleep
import math
potPin=0
myPot = ADC(0)
redPin=5
redLED=PWM(redPin)

while True:
    potVal = myPot.read()                     # 0 to 4095
    writeVal=100**(potVal/4095)-.005
    redLED.pulse_width_percent(int(writeVal))
    print(potVal,writeVal)
    sleep(0.1)

#!/usr/bin/env python3

from fusion_hat.adc import ADC

from fusion_hat.pwm import PWM

from time import sleep

import math

potPin=0

myPot = ADC(0)

redPin=5

redLED=PWM(redPin)

while True:

potVal = myPot.read() # 0 to 4095

writeVal=100**(potVal/4095)-.005

redLED.pulse_width_percent(int(writeVal))

print(potVal,writeVal)

sleep(0.1)

AI on the Edge LESSON 6: Digitial Out, Servos, Analog In and PWM on the Fusion HAT+

April 15, 2026 admin

In this video lesson we will become familiar with the FUSION AI HAT+, and we will learn how to do digital inputs and outputs, analog in readings, analog outputs, PWM and how to control servos. By the end of the lesson you should have the essentials you need to work with the Fusion HAT+. The schematic for the circuit we will be using in today’s lesson if below. We describe it in more detail in the video. The schematic is:

In the video lesson we demonstrated the following programs:

Digital output to blink an LED:

from fusion_hat.pin import Pin, Mode
import time
LEDPin=17
redLED = Pin(LEDPin,mode=Mode.OUT)
while True:
    
            redLED.high()
            time.sleep(.1)
            redLED.low()
            time.sleep(.1)

from fusion_hat.pin import Pin, Mode

import time

LEDPin=17

redLED = Pin(LEDPin,mode=Mode.OUT)

while True:

redLED.high()

time.sleep(.1)

redLED.low()

time.sleep(.1)

PWM Example to Control RGB LED Color and Brightness.

from fusion_hat.pwm import PWM
from time import sleep

redPin = 5
greenPin = 6
bluePin = 7

redLED = PWM(redPin)          
greenLED=PWM(greenPin)
blueLED=PWM(bluePin)
redLED.freq(200)
greenLED.freq(200)
blueLED.freq(200)

while True:
    for bright in range(0, 101, 1):
        redLED.pulse_width_percent(bright)
        sleep(0.01)
        print(bright)
    for bright in range(99, 0, -1):
        redLED.pulse_width_percent(bright)
        sleep(0.01)
        print(bright)

from fusion_hat.pwm import PWM

from time import sleep

redPin = 5

greenPin = 6

bluePin = 7

redLED = PWM(redPin)

greenLED=PWM(greenPin)

blueLED=PWM(bluePin)

redLED.freq(200)

greenLED.freq(200)

blueLED.freq(200)

while True:

for bright in range(0, 101, 1):

redLED.pulse_width_percent(bright)

sleep(0.01)

print(bright)

for bright in range(99, 0, -1):

redLED.pulse_width_percent(bright)

sleep(0.01)

print(bright)

Reading Analog Voltages on the Pi 5 Using the Fusion HAT+

from fusion_hat.adc import ADC
from time import sleep

potPin=0
myPot = ADC(potPin)       # A0–A3 on HAT

while True:
    analogIn = myPot.read()
    voltage=analogIn*(3.3/4095)
    print("Analog In: ",analogIn,"Voltage: ",round(voltage,2))
    sleep(0.1)

from fusion_hat.adc import ADC

from time import sleep

potPin=0

myPot = ADC(potPin) # A0–A3 on HAT

while True:

analogIn = myPot.read()

voltage=analogIn*(3.3/4095)

print("Analog In: ",analogIn,"Voltage: ",round(voltage,2))

sleep(0.1)

Controlling Servos With the Fusion AI HAT+

from fusion_hat.servo import Servo   # Import the Servo class for controlling servos
import time
# Import sleep for timing delays
panPin=2
tiltPin=3
servoPan = Servo(panPin)
servoTilt=Servo(tiltPin)
servoPan.angle(0)
servoTilt.angle(0)

from fusion_hat.servo import Servo # Import the Servo class for controlling servos

import time

# Import sleep for timing delays

panPin=2

tiltPin=3

servoPan = Servo(panPin)

servoTilt=Servo(tiltPin)

servoPan.angle(0)

servoTilt.angle(0)

AI on the Edge LESSON 5: Understanding Fusion AI Hat+ For Raspberry Pi

April 9, 2026 admin

In today’s lesson we will become familiar with the capabilities of the Fusion AI Hat+ for the Raspberry Pi. This hat will be a core part of our class moving forward. The hat makes it easy to get data from the outside world, and to control things in the outside would. We will get an understanding of the core capabilities of the board, and your homework will be to build the first circuit with the board. This schematic shows the various parts of the board:

Fusion AI Hat for Raspberry Pi Schematic

Then for the homework, we need you to go ahead and build this circuit. This circuit will allow us to learn how to make Digital Output commands, PWM commands, and how to read analog inputs.

In this video lesson, I show you my solution to the Homework Assignment in LESSON #3. If you were not able to do the homework yourself, you can follow along in the video. Make sure you can do it on your own, without checking back to my solution. You need to understand these basics before moving on the class.

This is my homework solution.

while True:
    bucket = 0
    numGrades = int(input('How Many Grades do you Have: '))
    grades = []
    for i in range(numGrades):
        grade=int(input('Enter Your '+str(i+1)+' Grade '))
        grades.append(grade)
        print('You Entered: ',grade)
    for i in range(numGrades):
        bucket=bucket+grades[i]
    myAverage=bucket/numGrades
    print('Your Grades Are: ')
    for i in range(numGrades):
        print(grades[i])
    print('Your Average is: ',myAverage)

while True:

bucket = 0

numGrades = int(input('How Many Grades do you Have: '))

grades = []

for i in range(numGrades):

grade=int(input('Enter Your '+str(i+1)+' Grade '))

grades.append(grade)

print('You Entered: ',grade)

for i in range(numGrades):

bucket=bucket+grades[i]

myAverage=bucket/numGrades

print('Your Grades Are: ')

for i in range(numGrades):

print(grades[i])

print('Your Average is: ',myAverage)
