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

When starting to solder, check whether the tip of the soldering iron is clean. If needed, clean the tip by poking the iron a few times in a brass sponge. A good tip temperature is 360°C. Tinning the iron tip (with a little solder) will improve heat transfer. Use solder specific for electronics. Do not […]

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 […]

How to use a multimeter

A digital multimeter (short DMM) is a tool that assists in the process to explore what’s happening inside components or in a circuit. Or when debugging your circuit. This guide will shortly explain how to setup your Digital Multi Meter and how to use it to do different measurements. Important for correct understanding: Ohm’s principal […]

Reading Analog Sensors

This tutorial has been created to explain the fundamentals of using analog sensors with a microcontroller. In this tutorial we use a thermistor (temperature dependent resistor) as example for sensing temperature . Understanding how to read this sensors and how to connect it gives you the ability to adapt to other analog sensors that change […]

Arduino and multi-tasking

This tutorial shows by means of a few examples how to program an Arduino to handle multiple tasks simultaneously. This is achieved by implementing the concept of finite state machines. Using finite state machines helps in creating a clear and flexible program structure. What is the problem? Intelligent systems get input from environment through  (groups […]
