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 multimeter is a tool that assists in the process to explore what’s happening inside components or in a circuit. Every meter multimeter has a “common” socket, color-coded black and labeled “COM”. Plug the black probe into this socket. You’ll also find a red-coded socket, labeled with the letter V and an ohm (Ω) symbol […]

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 […]
