Tutorial 10: Ten Arduino Projects for Absolute Beginners

Tutorial 10 – Pages

This tutorial series features ten Arduino Projects for absolute beginners. The projects have been selected from the Arduino IDE built-in examples, so no code needs to be downloaded – all programs or sketches can be loaded to the Arduino straight from the IDE.

Only a few basic electronic components are needed to build these projects, which are built on an electronic breadboard. The projects are a great way of exploring some of the capabilities of Arduino.

To be clear, this is a 10 part series of small Arduino project within the 20 part electronics course called Start Electronics Now! Navigation of the ten projects can be done using the menu at the top of the page, or the links at the bottom of the page. Navigation for the Start Electronics Now! course can be done using the main menu at the right of this page.

Beginner Arduino Project Example

The image below shows one of the Arduino projects for beginners – the barGraph project. As the potentiometer is turned in one direction, the LEDs light up in turn. When the potentiometer is turned in the other direction, the LEDs turn off in turn.

Complete Tutorial 3: Starting with Arduino and Tutorial 9: Using the Arduino Serial Port. It is also recommended to complete Arduino tutorial 4 and tutorial 7. All of these tutorials are part of the Start Electronics Now! course for beginners in electronics.

Read about potentiometers, LDRs and piezo disks.

Components for the Ten Arduino Projects for Absolute Beginners

Electronic components needed to build all ten of the Arduino projects are listed below. Of course, not all parts are needed if you are not going to build all ten projects, although it is recommended that beginners do build all projects.

Besides an Arduino Uno board, USB cable, wire links and a breadboard, you will need:

Qty Part Notes Type
1 1M ohm resistor (1 meg ohm) (brown - black - green) 1/4W, 5% or better Resistor
1 10k resistor (brown - black - orange)
1 4k7 resistor (yellow - violet - red)
10 220 ohm resistors (red - red - brown)
1 100 ohm resistor (brown - black - brown)
10 LEDs (e.g. red or green 3mm or 5mm LEDs) Semiconductor
1 LDR (Light Dependent Resistor) Transducer
1 Piezo disc
1 8 ohm loudspeaker
1 push button or toggle switch Or just a wire link will do Switch
