PCB designing is a vital step in every product development cycle. The below list provides you with a collection of DIY PCB Projects which can be used to develop PCB designing skills. Each project consists of a useful practical circuit that is demonstrated with a neatly fabricated PCB. The design details including the Gerber file is available for download to provide a complete do-it-yourself experience.
The MAX32690 evaluation kit provides a solid foundation to explore the full capabilities of the MAX32690 microcontroller, which is an advanced system-on-chip (SoC). It features an ARM Cortex-M4F CPU for efficient computation of complex functions and algorithms. It features the latest-generation Bluetooth 5 Low Energy (Bluetooth LE) radio designed for wearable and…
Human brain is built of complex layer of structures which helps us to be a dominant species on earth. For example the entorhinal cortex in your brain can give you sense of direction helping you to navigate easily through places that you are not familiar with. But unlike us, Robots and unmanned Ariel vehicles need something to get this sense of direction so they could…
When it comes to giving your projects wireless capabilities, the 433Mhz ASK Hybrid Transmitter and receiver is a common choice among engineers, developers, and hobbyists because of Its Low Price, easy to use libraries and its community support. We have also built few projects like RF controlled Home Automation and Wireless Doorbell using this 433MHz RF module. But often-…
When developing electronic projects, the power supply is one of the most important part of whole project and there is always need of multiple output voltage power supply. This is because different sensors need different input voltage and current to run efficiently. In this scenario, a power supply which can output multiple voltages becomes very important. There are options…
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…
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…
An edge avoider robot is quite similar to my previous project "Line Follower Robot". This 8051 microcontroller based robot detects an edge and avoids it by turning or stopping. Let us see how can we design a edge avoider robot easily.
Concept of Edge Avoider Robot
Concept of Edge Avoider robot is same as line…
In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications. We designed an isolated PCB for 3 relays. By using this Arduino Relay Shield, we can operate 3 AC appliances at a time. We have put a two pin screw terminal blocks (Neutral, NO) for connecting appliances. Here we have provided PCB layout, circuit…
Be it the long stretched highways or your doctors front door, we have sign boards placed everywhere to provide us information. But these sign boards are often boring and cannot be configured as per our interest from time to time. So in this project we are going to build a Bluetooth controlled Sign board using an 8*8 Matrix display. A unique feature of this project is its…
In this project we are going to build a Digital Voltmeter without using any microcontroller. Here we are using a very popular IC for voltage measurement namely ICL7107/CS7107. Using ICL7107, we can build accurate and very low cost voltmeter. ICL7107 is a 3.5 digit analog to digital converter (ADC) which consumes very low power. The IC has internal circuit for driving…
In this project, we are going to make a Voice Modulator Circuit, by using self-designed PCB. In this project, we have designed a PCB using EASYEDA online PCB simulator and designer. This is a fun project, mainly designed for changing or altering the voice. Generally, when we speak in a MIC we hear same voice. But in this project when we speak in MIC, we will hear a little…
Electronics has always been fun to play with, once we learn the very basics of how each component works and how to use them in our circuit it’s fairly easy to design, simulate and fabricate our ideas into a PCB. In this project let’s build a simple fun circuit, analyse it and then fabricate a PCB to improve our learning curve. The concept behind this Lie Detector Circuit is…
