If you’re like me and you’re doing work with an Arduino or a Raspberry Pi, you are going to want to hook it up to something. Now the something might just be a simple button or an LED, or it might be more sophisticated like an infrared receiver or a heat sensor. If that’s you, then you want to consider getting this:  KEYESTUDIO 37 in 1 Sensors Starter Kit for Arduino Mega R3 Nano Raspberry Pi Projects (on amazon.ca).

It says Sensors starter kit, but it has a nice collection of LEDs and buttons, too. Each of the 37 items are easy to plug into a breadboard or you can connect them to your Pi or Arduino with wires.

Other great things:

• the sensors are all labelled. That means you won’t be pick one up months from now and asking yourself: what does this do?
• their documentation is really good. It’s online, here. (Note, their site is slow: I printed the long web page into a PDF that I can quickly refer to.)
• The sensors have their own resistors built in. That way you don’t have to put your own resistors between the Pi and an LED, for example.
• there is a wide variety of sensors in this kit. You will be able to do many a project with all these sensors.

I’ve purchased sensors in the past, and the problems I’ve had with them are gone due to this kit. I’m glad I bought it.
