Motion Sensor Alarm

The objective of this project is to create a motion sensor that triggers a red light and buzzer when it senses movement. You can use this alarm to trigger a variety of outputs, such as lights, motors, or even a “welcome home” message when you approach your front door.

This is Project 21 from the Arduino Project Handbook, V.1, by Mark Geddes. We built it using a WorkBench 1007 Project Development Kit.


LED Bar Graph

This project is an LED bar graph — a series of LEDs — that you control with a potentiometer. You can think of the potentiometer as a “dimmer switch”, but you could substitute anything that puts out a varying analog signal, such as a microphone.

This is Project 3 from the Arduino Project Handbook, V.1, by Mark Geddes. We built it using a WorkBench 1007 Project Development Kit.


Weather Station

In this project, you will create a weather station to measure and monitor temperature and humidity. The values will be displayed on an LCD screen. This project would be great to monitor indoor plants, a terrarium, or even outside weather conditions.

This is Project 13 from the Arduino Project Handbook, V. 1, by Mark Geddes. We built it using a WorkBench 1007 Project Development Kit.


Pushbutton LED

In this project you will learn how to wire a button to control the Arduino and have it turn on an LED light.

Unlike general use single board computers like the Raspberry Pi, the Arduino – like other microcontrollers – does not have an easy way to receive commands. That is, it lacks a simple human-machine interface. By programming your Arduino to respond to something like a button, you begin to harness the power of this microcontroller.

This is project 1 from the Arduino Project Handbook, V1 by Mark Geddes. We built it using a WorkBench 1007 Project Development Kit.


LED DIMMER

In this project, you create a dimmer switch by adding a potentiometer to control the brightness of an LED. You will learn how a potentiometer functions and interacts with the Arduino, which effectively "translates" analog signals into digital.
