Microcontrollers are basic prototyping boards you can use to make simple electronics.  It's one of the best ways you can get started with electronics and coding.  Basically, microcontrollers can be programmed to interact with other electronics components that connect to the microcontroller via the microcrontroller's "General Purpose Input and Output (GPIO) headers". The GPIO headers are also called "pins". Here are some of the types of microcontrollers that are available to students at the Idea Shop.
The Arduino Uno is a basic prototyping board you can use to make simple electronics.  It's one of the best ways you can get started with electronics and coding.  Basically you can code the board to give specific outputs, based on inputs on specific pins.  It's one of the most well documented microcontrollers, so if you're looking for something specific, the chance is someone has tried to do it already and google will be your best friend. If you're looking to get started with Arduino from little to no basic coding knowledge, here is a tutorial on how to do it that goes through some of the basics and leaves room to expand: https://docs.google.com/document/d/1WBJcONsipZW8AqFeg47Jnr9jpsoVE378khvsaSx-Pe4/edit?usp=sharing

An oscilloscope is a laboratory instrument commonly used to display and analyze the waveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time.  Oscilloscopes display the change of an electrical signal over time, with voltage and time as the Y- and X-axes, respectively, on a calibrated scale. The waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Modern digital instruments may calculate and display these properties directly. To learn more, click '''[https://www.youtube.com/watch?v=u4zyptPLlJI here]'''.

Microcontrollers

Main Article : Microcontroller Comparison
An Arduino Uno

Microcontrollers are basic prototyping boards you can use to make simple electronics. It's one of the best ways you can get started with electronics and coding. Basically, microcontrollers can be programmed to interact with other electronics components that connect to the microcontroller via the microcrontroller's "General Purpose Input and Output (GPIO) headers". The GPIO headers are also called "pins". Here are some of the types of microcontrollers that are available to students at the Idea Shop.


Oscilloscopes

One of the Idea Shop's Oscilloscopes

An oscilloscope is a laboratory instrument commonly used to display and analyze the waveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time. Oscilloscopes display the change of an electrical signal over time, with voltage and time as the Y- and X-axes, respectively, on a calibrated scale. The waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Modern digital instruments may calculate and display these properties directly. To learn more, click here.

Soldering Irons

A Weller Soldering Iron

If you'd like to learn how to solder, check out the beginners guide here: https://www.makerspaces.com/how-to-solder/. This section will focus on information about the soldering irons we have.

Here is a soldering tutorial for beginners.

Our electronics benches are equipped with Weller WES51 soldering stations connected to Weller soldering irons. Our soldering station has a variable temperature, the number on the dial is 1/10th of the actual temperature of the iron in Fahrenheit. For example, when soldering through hole components you'll want to set the dial to 70 which represents 700 degrees Fahrenheit.

Make sure you always put down butcher paper before you start soldering, solder can easily ruin our nice wooden tables

Desoldering Tool

Hakko FM-2024 Desoldering Tool

Our desoldering tool is a Hakko FM-2024. The purpose of this tool, as you can imagine, is to remove solder.

You'll use the end of the tool to heat up the joint, and pull the trigger when the solder is liquefied to suck it into the gun. This deposits the solder into the insulated orange canister you'll see at the top of the gun.

This chamber can easily be replaced when full, and can be checked by simply pulling the yellow guard back towards the gun. The guard will click into place, and you can remove the orange canister. When you replace the canister into the gun, simply hit the yellow button on the top of the gun to release the spring.

You'll need to adjust the temperature of the Desoldering Tool as you would the soldering iron, since the goal of the tool is to liquefy the solder.

Here is a tutorial video for beginners.

Step Up & Down Transformer

A 110V-220V Step Up/Down Transformer

A transformer is a set of 2 magnetically-linked inductive coils with different numbers of "turns" of wire in each. When Alternating Current is passed through one coil at a certain voltage, a different voltage will appear across the other coil. The ratio of the voltages will the the opposite of the ratio of the numbers of turns. Depending on which coil is the input and which is the output, the output voltage will be greater than or less than the input voltage, hence, Step Up and Step Down.

The SMD Rework station is a tool we use to solder and desolder Surface Mount Devices. SMD's are components that are soldered directly to tabs on circuit boards, rather than having leads that go through the circuit board.
