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.
This will be the fifth tutorial in our PIC Tutorial Series, which will help you to learn and use Timers in PIC16F877A. In our previous tutorials, we had started with Introduction to PIC and MPLABX IDE, then we wrote our first PIC program to blink the LED using PIC and then made a LED Blinking Sequence by using delay function in PIC Microcontroller. Now let us use the same…
When developing robotic projects, motors are one of the most important parts of the whole project and there is always a need for multiple motors. But GPIO pins of the Microcontroller boards don’t allow you to draw the amount of current required for a motor. That’s why the motor driver ICs are used. You can build a motor driver circuit by using some electronic components or…
A Raspberry Pi HAT is an add-on board for Raspberry Pi with the same dimensions as Pi. It can directly fit on the top of Raspberry Pi and doesn’t require any further connections. There are many Raspberry Pi HATs available in the market. In this tutorial, we are going to build a Raspberry Pi Motor Driver HAT to drive DC and Stepper motors. This Motor Driver HAT consists of an…
In this DIY session, we make an Arduino Motor Driver Shield to drive DC motors, stepper motor and Servo Motor. Compatible with Arduino UNO and Arduino Mega, this motor driver shield can operate 4 DC motors or 1 stepper motor and 2 servo motors at a time. Here two L293D Motor Driver ICs are used for driving motors and an 8-bit shift register for controlling…
In this article, we are building an AC Fan Regulator Circuit, which is able to control the speed of the fan by restricting the flow of current to the fan. The term AC Ceiling Fan Regulator is a mouthful, hence we will simply call it a fan regulator from now on. A fan regulator circuit is a crucial component that is used to increase or decrease the speed of an AC Fan/motor…
In this project we are going to build a cell phone controlled robot using 8051 microcontroller. Cell phone controlled robot runs over mobile DTMF technology. DTMF stands for Dual Tone Multiple Frequency. There are some frequencies that we use to create DTMF tones. In simple words by adding or mixing two or more frequencies we generate DTMF tone. These…
In many cases, ESP32 capacitive touch sensors are used instead of push buttons. The advantage is that we don't have to provide force to press a button, and we can activate a key without touching it using touch sensors. Touch-sensing technology is becoming popular day by day. And within the last decade or so, it has become difficult to imagine the world without touch-…
Raspberry Pi HAT is an add-on board for Raspberry Pi with the same dimensions as Pi. It can directly fit on the top of Raspberry Pi and doesn’t require any further connections. There are hundreds of Raspberry Pi HATs available in the market and we also built Raspberry Pi Hat for 16x2 LCD. In this session we are going to build a LoRa Hat for Raspberry Pi on PCB. This…
With the advancement in virtual assistants like Google Assistant and Alexa, Home automation and Voice controlled applications are becoming normal. Now, we ourselves have built many home automation projects, from simple Automatic Staircase Lights to IoT based web controlled Home Automation using Raspberry Pi. But this project here is different, the idea here is to create a…
In this project, we are going to make a Headphone/Audio Amplifier by using self-designed PCB. This project is mainly designed for amplifying the audio signal from the headphones but we can also use it for amplifying the subwoofer or speaker output, just by switching few jumpers.
When we use headphones with our audio device like mobile, laptop, FM…
The LA4440 is a very popular dual-channel audio amplifier commonly used to build high power audio amplifiers. The IC is known for its high power, easy availability and cheap price which makes it popular among Home Theatre and Car Amplifier Systems which operate on 12V. Hence in this article, we will learn how to build a High-Power Stereo Audio Amplifier using the LS4440…
Raspberry Pi Hats are the same as shields for Arduino, they can directly fit on the top of Raspberry Pi and don’t require any further connections. Here we are going to build an RGB LCD Hat for Raspberry Pi on PCB. This LCD Hat consists of a 16x2 LCD module, five switches, and three NeoPixel LEDs. Here switches are used to change the text on display and NeoPixel LEDs are used…
