Breadboard - We use a "170 Points Mini Breadboard" in this project, which is the smallest breadboard that we know of. Needless to say, you can use any other larger-sized breadboard.
Breadboard Jumper Wires - Any size breadboard jumper wires kit will suffice for this project. We recommend using stiff wires, as it provides cleaner final look to your project.
LEDs - Any LEDs will work fine. They are available in many electronic shops. For this project, you'll need 4 in total, but since they are useful for any number of projects and are relatively cheap, we like to buy them in bulk.
ESP32-C6 controller - The goal of this project is to be done without soldering. For that, we have chosen a pre-soldereded variant. You can buy one that is not soldered and solder the pin headers yourself, but that will be a bit more difficult, as the display is covering the plated through-holes, so we strongly recommend buying a pre-soldered one unless you feel very comfortable with your soldering skills.
Active Buzzer - The only requirement for this one is to work with the 3,3V that the controller can put out.
220 ohm resistors - You need only 4 resistors for this project, and any 220 ohm resistors will do the job. They can be found in any electronics shop and are very cheap. Most of the price on those is the delivery, so we recommend buying a bit more to use in future projects, since the 220 ohm resistors are amongst the most used resistors for DIY projects
Buttons - These can be found in most electronic shops. For this project, you need 4, but since they are very cheap, we recommend buying more, so you can use them for other projects as well.
