To get started with the IoT Project Kit, you only need a small set of inexpensive components. The goal is to keep the entry point simple and affordable, while allowing you to expand into more advanced projects over time.
This site is currently focused on learning with the Arduino Uno R3 and a specific 37-in-1 sensor module kit.
Once you have the basics below, you’ll be able to build dozens of beginner and intermediate projects right away.
What You Need to Start
1) An Arduino Microcontroller (the brain of your projects)
The recommended starting board for this site is:
Arduino Uno R3
This is one of the most widely used microcontrollers in the world and is perfect for learning electronics, sensors, and basic automation.

Other Arduino boards can be used later, but all beginner content here is built around the Uno R3.
2) The 37-in-1 Sensor Module Kit
This kit contains a wide variety of sensors and output modules such as:
• buttons
• LEDs
• photoresistors
• temperature sensors
• rotary encoders
• buzzers
• infrared sensors
• and more
These modules allow you to learn one concept at a time and then combine them into more complex systems.
Important:
This sensor kit does not include a breadboard or jumper wires — those are purchased separately below.

3) Breadboard and Jumper Wires
You’ll need:
• at least one breadboard
• a set of male-to-male jumper wires
These are what allow you to connect sensors and components without soldering.

Once you have these three items — Arduino, sensor kit, and wiring — you’re ready to start building projects.
A Simple Starter Setup (Typical Cost)
A very affordable beginner setup is:
Arduino Uno R3
37-in-1 Sensor Module Kit
Breadboard + Jumper Wires
Total is typically around $75–$85 USD depending on sales and availability.
(Prices on this site update automatically with Amazon.)
Optional Add-Ons (Unlock More Projects)
You can do a lot with just the basics above.
As you progress, adding a few low-cost items opens up many more projects.
Resistor Kit (Highly Recommended)
A small resistor assortment allows you to:
• use individual LEDs
• build voltage dividers
• work with analog sensors
• create more advanced circuits
This unlocks a large number of intermediate projects.

Boards With Built-In Connectivity (Later Upgrade)
Once you’re comfortable with the basics, you may want a board that includes WiFi or Bluetooth.
These allow you to build:
• web-connected sensors
• phone-controlled devices
• remote monitoring systems
These are optional and not required for beginner projects.
Add-On Modules for Advanced Builds
Over time, this site will introduce additional low-cost modules such as:
• RFID readers
• I2C devices and displays
• motor controllers
• digital-to-analog converters
Some are available pre-assembled, while others may require light soldering.
These expand what you can build once you’re comfortable with the basics.
