Relays are frequently used in our electronics applications specially when we need to drive high loads from microcontroller circuits. So in this DIY project, we make a 4-Channel Relay Driver Circuit to be used in relay based applications. In-here we have designed an isolated PCB for 4 relays to operate 4 AC appliances at a time. We have put a three pin screw terminal…
The simple current source is not perfect for variable loads as the current through load also changes with the load resistance. The solution for this problem is a Constant current source like Howland Current Pump Circuit.
The Howland Current Pump was invented in 1962 by Professor Bradford Howland from MIT. It consists of an operational amplifier IC…
Security systems play an important role in our day to day lives and there we can find a lot of different types of security systems with different kinds of technologies and with different price range. Being an electronic enthusiastic you can make a simple security system by spending few bucks and some spare time. Here in this article I am sharing a DIY guide to make a…
Power consumption is a critical issue for a device running continuously for a long time without being turned off. So to overcome this problem, almost every controller comes with an Arduino sleep mode, which helps developers to design electronic gadgets for optimal power consumption. Sleep mode puts the device in power-saving mode by turning off the unused module. Whether you…
Power amplifier is the part of audio electronics. It is designed to maximize the magnitude of the power f given input signal. In sound electronics, the operational amplifier increases the voltage of the signal, but unable to provide the current, which is required to drive a load. In this tutorial, we will build a 50 Watt RMS output power amplifier using MOSFETs …
Graphical representation is always helpful to visualize the data and it becomes very easy to find trends and patterns by looking at them. There are many software available to plot graphs based on the input values, but in embedded system MATLAB is one of the most popular software which can not only present the results in graphical format but also can be easily integrated with…
A stepper motor is a type of DC motor that works in discrete steps and used everywhere from a surveillance camera to sophisticated robots and machines. NEMA 17 stepper motor has a step angle of 1.8° that means it will take 200 steps for a 360° rotation. By changing the rate of the control signal applied, we can easily control the motor speed. Stepper motor can be…
Flashlight or Torch is very useful in emergency situations like power failure. These flashlights are battery-operated, and we have to charge regularly in particular intervals. But what if you don’t have electricity and your flashlight is dead? In that situation, Mechanical chargeable Flashlights is very good option, which can be charge by rotating the lever attached to it.…
In previous article, we covered various Music streaming softwares which can be installed on Raspberry Pi. Here we will pick one of them and install it on Raspberry Pi. Since we covered the installation of media servers like Kodi and Plex in our past tutorials, I feel this time, we should turn the spotlight towards the audiophiles and cover installing one of the music servers…
In our previous tutorial, we learnt about Blinking a LED using PIC microcontroller and built the same circuit on Perf board. Then we used PICkit 3, ICSP and MPLAB IPE for dumping the program onto our Perf board. Now, in this tutorial we will advance our self to using more pins on the PIC microcontroller. We will use 7 outputs (LEDs) and one Input. For this tutorial we will…
Capacitors seem all fine till you get to the point where a power supply fails or refuses to perform optimally. And if the problem is noise, there is a simple fix, you just add more capacitors. But that does not solve it. What could be wrong?
The problem arises from the naïve assumption that capacitors (to a large extent) are ‘ideal’ devices, while…
Analog to digital conversion is a very important task in embedded electronics, as most of the sensors provide output as analog values and to feed them into microcontroller which only understand binary values, we have to convert them into Digital values. So to be able to process the analog data, microcontrollers need Analog to Digital Converter.
