An FM transmitter is one of the most popular devices between electronic hobbyist, professionals and even non-technical people. In this article, we gonna learn to how to build an easy, stable and digitally controllable FM transmitter.   For this design, I have selected the VMR6512 module which truly is like a full RF block on a chip!. It eliminates all essential circuitry for a basic FM transmitter such as inductors and trimmers. According to the VMR6512 datasheet: “VMR6512 is a highly ...
Motor driver circuits are one of the most useful designs for industrial, automotive and robotic applications. Full control over a DC motor is an essential function for a variety of applications. For many low power applications, 1A to 1.5A RMS current consumption limit/per motor is enough, therefore I selected a useful chip that can operate with just a few external components.   The DRV8833 chip is a dual H-bridge motor driver. According to the datasheet: “The DRV8833C device is an int ...
As today is May the fourth, Star Wars Day, I thought I'd share some images from Star Wars Celebration in Chicago earlier this year, as well as, invite you to take our 2019 Star Wars Day poll!   You can also take the poll from last year if you haven't done so already!   My Gallery Title   BB8 was there.....     NOT from Star Wars Celebration but a good memory of R2D2 from Maker Faire 2017...     Poll https://www.element14.com/community ...
A typical HD4470 character LCD comes with 16 pins. If we ignore the backlight and the power pins, the 8 data and 3 control pins remain. We can address the LCD in the 8 bits or 4 bits mode. Therefore we have to consider at least 11 I/Os (8 bits) or 7 I/Os (4 bits).   The circuit design could be more complicated when we realize most of these LCDs just operate with a 5V supply and typically they are not compatible with 3.3V MCUs. Many modern MCUs offer 5V tolerant pins but naturally in a limit ...
An obstacle detection unit is an essential part of a variety of projects, such as robotics and security applications. The infrared sensors are widely used for these types of applications. The main drawback of some circuit designs is that the detection units are sensitive to the outside lights and react unstable or noisy. In this project, we selected a proper IR receiving component and designed the circuit in a way to act as stable as possible. Also, you can adjust the sensitivity of the sensor t ...

Clustered MCUs Enter Your Electronics & Design Project for Your Chance to Win a Grand Prize for the craziest project or a $100 Shopping Cart! Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   Here's my idea I'm afraid I did not quite have time to get it completed as I've had lots of other things on.   My first thought was what is the cheapest MCU I can find? I spotted the ATTiny10 chips for just 25p each so bought a handful of these along with ...
