Recently I came to understand the true demand for a multi-purpose digital pulse counter. So I designed an east-to-build digital pulse counter circuit based on some generally available cheap electronic components. The quick microcontroller based […]
Water Pressure Sensor is not a familiar everyday sensor for most electronics hobbyists and makers, so here’s an introductory tutorial on a popular water pressure sensor – the DFRobot Gravity: Analog Water Pressure Sensor. In […]
Resistor color code indicates that a series of colored bands are painted on the resistor and most of the manufacturers identify their resistance value by means of a color code. There are various values of […]
Here’s a travel door sentry to safeguard your hotel room with a simple door sensor that will trip a warning alarm if anyone unlocks the door and intrudes. The battery-operated portable security device is very […]
Let me introduce another simple do it yourself project, this time an electronics thermostat for residential electric water heaters. The circuit is designed for use in two-element water heaters in the upper position (upper thermostat), […]
Temperature coefficient of resistance, this is the factor that temperature does affect the value of resistance in a resistor or a conducting wire. All the resistors value of resistance is specified at specific temperature and […]
And now another interesting little project. After seeing numerous online projects I decided to build my own simple NiMH battery charger circuit using NiMH batteries because a bunch of GP2100 series NiMH cells are lying on […]
In this guide we will learn how to play with a cheap ‘n’ cheerful temperature and humidity sensor DHT11 – the minuscule 4-pin sensor accurate enough for most do it yourself projects need to read […]
Voltage Divider and Current Divider are the most common rules applied in practical electronics. As you know, there are two types of combinations in a circuit, they are series and parallel connections. Parallel circuits are […]
Conductance, Temperature coefficient, resistivity and specific resistance are the properties of an electric conductor or any other material. They all can be understood by resistance. Resistance is the amount of obstruction in the flow of […]
