PWM is used in many industrial mostly for controlling the motor speed. The PWM is used because it’s the most efficient method comparing to the analog one. That’s why most of the modern microcontrollers today have this features build in. How does this PWM works will be described on the following circuits: On the figure 1A …

And now for something completely different: A little robotics project for the weekend. The described robot can be build entirely from model making supplies and materials from the hardware store. Also only very few tools are needed. A metal saw, a drill press, a vice and optionally a tap will suffice. And here you can …
What this is: This instructable will show you how to make your Arduino into an R/C interface that you can use for just about anything requiring remote control. I will also show you how I built an R/C lawnmower using my Arduino, a cheap R/C transmitter and receiver pair, and a couple of electric-wheelchair motors from Ebay. I have used …

Ever wanted a robotic liquor server?I purchased a Lynxmotion robotic arm last year and an Arduino (deci) to play around with. I had it serial controlled with a joystick and it was a great way to start in robotics. More recently I wanted to take on another micro-controller related project for a university science fair. …

I’m an Electrical Engineering major and each year my college’s branch of IEEE competes in a student hardware competition. Last year’s competition was inspired by the natural disasters in Haiti and Chile (the competition was held one week after the earthquake in Japan). This was a very large project that was tackled by a group …

Halloween Robot controlled by an old wingman joystick. I don’t reccommend this for beginners with electronics only because some things like joysticks and power adapters are not all the same and must be modified. Additionally I provide programming code which will only be useful for particular stepper motors without modification. **This is still unfinished, but …

Tired of putting LEDs every time you want to check some value in the microcontroller? Well, its time to build yourself a debugger. A debugger is a device which helps you run through your code in the microcontroller step by step and also gives you the ability to read or write the registers directly using …
This project gives a speed control of DC motor through PWM method. The Dc motor is derived by the L298 driver IC. You can also control the direction of the motor. There are three buttons to control the motor. Also a bar graph Led display indicate the speed of the motor. An proteus simulation file is also available at the download …
Introduction This project uses an Arduino microprocessor and a MAX522 8 bit serial DAC to produce arbitrary low frequency oscillator (LFO) waveforms. These waveforms are useful for driving a tremolo/vibrato circuit in a guitar amplifier such as the Lil Tiger or the Hammonator 2RVT. This is a second generation version of this project, see the first version for reference. The first prototype …
