This book gives complete directions for students to complete an Arduino circuit turning on and off 8 LEDs. There are multiple codes taught in circuit 4. I have broken them into 4A, 4B, 4C and 4D. This allows students time to process the different ways to achieve the same task. At the end of the book are reflection questions for students to answer. The book also contains a troubleshooting section.
Students can complete this work independently and at their own pace.
