Microcontrollers are standalone chips since they have memory and processor embedded. The integrated memory of microcontrollers store embedded code and other temporary variables for the execution of program. CircuitsGallery published many microcontroller tutorials and PIC microcontroller projects. Sometimes we may use non-volatile memories (i2c devices) with microcontrollers in case of storing permanent data. In this […]

This project is specially designed to measure surface mount capacitors in the range 1p to 920n and electrolytics in the range 1u to 100u. The biggest problem with surface mount capacitors .  .  .  they are not identified! And you cannot determine their value by the size of the component. This makes it very difficult. […]

Having had a bit of an unproductive Easter break I think it’s about time I got back to posting the concluding details of how the transmitter for the Bluetooth RC was implemented. I built the PIC-based motor and servo controller before acquiring the BlueSMiRF module so initially I wrote the following simple Python script based […]

In this project we are going to establish a wireless communication between two ESPs and send data from three sensors to an Excel spreadsheet. This tutorial shows a wireless weather station with data logging that you can implement in your home. Before you continue reading this project, please complete the following tutorials:  How to get started with the ESP8266 […]

Spansion has added two more ARM Cortex-M4-based microcontrollers to its portfolio: the FM4 S6E2DH with an integrated graphics display controller and the S6E2CCxxF/MB9BF568F with self-contained voice command control. “These new product families enable customers to design intuitive next generation human machine interface (HMI) systems,” says Spansion’s Dhiraj Handa.The S6E2DH combines an ARM Cortex-M4 core based […]

PIC Programmer MkV is designed to get you into PIC Programming for just a few dollars. It uses just 12 components. Most of them will be in your “junk-box” and the PC board is a small piece of matrix board. It’s the cheapest way to get started. As well as PIC PROGRAMMER MkV you will […]

GSM Modem Interface with PIC 18F4550 Micro controller: Description: In this project we use PIC 18F4550 Micro controller in transmitter section keys are connected to PB0 to PB3. If we press the key PB0 the Pressed Key Value is transmitted to the micro controller section i.e receiver section . In the controller we pre programmed […]

The goal of this project is to learn as much as possible about the Zsun WiFi card reader and run OpenWrt on it to turn it into an awesome wifi device. UPDATE 2016-04-23 The new PCB is missing a jumper on the RX serial line, see serial port section UPDATE 2016-03-16 The second PCB revision […]

I was trying to think of a suitable name for this project, and after literally seconds of careful deliberation, I gave up and decided to call it Fluffy. Sorry. Anyway, Fluffy is a SX programmer for people who havealready experimented with PIC chips, and want to try out the Scenix SX family. I built Fluffy […]

2-Wire LCD Interface for the PICMicro Alphanumeric LCD displays have become very popular for microcontroller applications because they can add a lot to a project in a variety of different ways. A text message giving the user instructions as well as feedback can make the application seem much more “professional” and easy to use. I […]
