In this project, I will go through the process of designing and making a flight controller board from scratch for a micro-quadcopter. This board will be based on the ATMega328 microcontroller and will be used to control four coreless DC motors. The whole PCB making process from designing of the schematic to [**custom circuit board**] is done using EasyEDA. If you are interested in the circuit p...

Since a lot of our followers asked for a tutorial to guide them to make a basic Robot we decided to provide this instructable that describe a step by step making of **LINE FOLLOWER Robot**, so you will find all the necessary software and hardware parts to make your own Robot following these steps
Note: In this project the main part was made usi...
This is a battery powered sensor board based on the ESP8266 (ESP-12F).
By using a TPL5111 chip the battery consumption can be reduced to about 1µA when the ESP is not enabled. When the TPL5111 chip receives 5V at it's wake up pin this will turn the ESP on by enabling the 3.3V voltage regulator. At this moment you can run any program you want. If you want to turn the ESP off again you have to drive...
In this project, we are going to use a PIC microcontroller to remotely control few AC loads by just using an IR remote. At the end of this project you will be able to toggle (ON/OFF) any AC load using an ordinary Remote from the comfort of your Chair/Bed. To make this project more interesting we have also enabled a feature to control the speed of the fan with the help of Triac. All these can be do...
Designing PCBs and **[PCB fabrication]** are getting a lot easier these days. The possibility of manufacturing 5-10pcs circuit boards at dirt cheap price has given millions of hobbyists an opportunity to work on their ideas freely. However, for a hobbyist or a beginner, even cheap services can become expensive if he/she is unaware of all the steps involved from designing to **PCB fabrication**...
Long story short, I decided to try out a **Cheapest PCB Prototype** -[JLCPCB]. Why I call “the Cheapest PCB Prototype .”Because i never experience so cheap price. Viewing the banner first time, I can’t believe the price :$2This is review is about only the **Cheapest PCB Prototype** service, so point one is that they support both modes.
**[Cheapest PCB Prototype] - JLCPCB Cost**
Cost was re...
I tried a new **quick turn PCB fabrication**:[JLCPCB ](https://jlcpcb.com/m ), Here is the review about JLCPCB. Since I still have some older versions of one of the boards, I could make a comparison with the two **quick turn PCB fabrication**. I decide to not mention which competitor I pitched JLCPCB against...
I’m a regular user of different **[PCB prototype]** services form my electronic design. I used several manufacturers of **prototype board**.
Since 4 year now I’m mostly working with Eurocircuit but recently I tested different PCB prototype services and low cost solutions : JLCPCB, Seeedstudio and OSH Park .This is now an opportunity to compare these different solutions.

**Stun gun** is a device which generates high voltage at it’s output by taking low voltage as input. Concept of this device is based on High volt inverter. Here we are building this **Stun Gun circuit on PCB** and below you can find the required circuit diagram and PCB layouts to build this stun gun yourself.
For complete details about the circuit with instructions on how to design this circuit...
One of the key concepts in electronics is the printed circuit board or PCB. It's so fundamental that people often forget to explain what a PCB is.
#What is a Printed Circuit Board?#
A [printed circuit board (PCB)] is a plastic board made for connecting electronic components together. These are used in almost all computers and electronics today.
A printed circuit board (PCB) mechanicall...
Carte d'asservissement d'un robot pour la coupe de france de robotique.
La carte comporte deux régulateurs de tension, un variable et un 5V.
La position du robot est calculée en temps réel par la carte STM32L432KC à l'aide des encodeurs. Suivant la commande reçue en I2C, un signal PWN est envoyé au L298N pour contrôler la tension des deux moteurs.
In this project, we will make a **4-Channel Relay Driver Module Circuit** for relay based applications. In this circuit, we have designed an isolated PCB for 4 relays. By using this **Relay Board**, we can operate 4 AC appliances at a time. We have put a three pin screw terminal blocks (NC, Nuteral, NO) for connecting appliances. Below are the circuit diagram and PCB layout designs of the relay dr...
