How to desolder

When soldering a circuit, it is almost inevitable to make mistakes or make connections where there should not be one. Also when using circuits, components may break and need replacement. That means there is a need to repair soldered connections. In this tutorial we will explain a few of the most common tools and their […]

Getting started: Teensy

This tutorial has been especially created to accompany the starterskit containing a Teensy microcontroller. It will cover most of the basic skills and help to get you started with electronics. During this tutorial you will be creating an interactive light; responding to approaching objects. It advisable to work in small teams. note: The Teensy is […]

Getting started: Arduino

This tutorial has been especially created to accompany the starterskit containing an Arduino Uno microcontroller. It will cover most of the basic skills and help to get you started with electronics. During this tutorial you will be creating an interactive light; responding to approaching objects. It advisable to work in small teams. note: Before you […]

Extensive example of using finite state machines

In this tutorial we will explore the use of finite state machines by looking at an example. The example we will use is a railway crossing. Main focus is this tutorial is to develop the code by using finite state machines as much as possible. In that way the advantages of using them becomes clear. […]

Oscilloscope measurements

An oscilloscope (in short ‘scope’) is a measurement instrument that shows a graph of how an electrical signal changes over time. And is often used when working with electronics. Before you can work with it, it’s important to have an introduction. The vertical axis of the graph represents voltage, and the horizontal axis represents time. […]

Using a lab DC power supply

This tutorial describes in short how to use the TTI lab power supply. But the information is also applicable for other DC power supplies. Features of the power supply. The lab power supply gives an adjustable stabilized DC (direct current; Dutch: ‘gelijkspanning’) output voltage between the specified range (e.g. 0 and 30 V DC). The […]

How to solder

Use solder specific for electronics. This solder has a flux core. Flux enables the solder to adhere to a clean metal surface and prevents the formation of oxides. Do not use soldering liquids. They are very aggressive for both iron and electronics and are not necessary for electronics soldering. They even damage component leads. Immobilize […]

Voltage divider

A voltage divider is a circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). Voltage division is the result of distributing the input voltage among the components of the divider. When calculating with impedance the principle is valid of any combination of two resistors, capacitors, and inductors. In […]

Haptic Feedback Driver – DRV2605L

Intro The DRV2605L is a break-out board motor driver especially designed for small haptic feedback motors. It comes pre-programmed with a whopping 117 different effects which in combination with the Arduino IDE are super easy to program. The DRV2605 supports two different kind of motors, the (Linear Resonance Actuator) and ERM (Eccentric Rotating Mass), where […]

Upload code to lilypad

This tutorial has been especially created to accompany the E-Lucid Wearable Senses kit. It will help to get you started with the Arduino Lilypad. In contrast to the Arduino UNO, the Arduino Lilypad does not have a chip on board that takes care of the communication between the microcontroller and your computer. Usually you would program […]
