Precision control of 2 DC brushed motors using encoders
Perhaps the most common part needed to build a robot is a motor controller and usually the first complaint from beginers is that the robot does not travel in a … Read more
Allows any Arduino board to accept commands from an IR receiver
Most homes these days have at least 1 infrared remote control for controlling the television. These remote controls can also be used to control robots or even to … Read more
Plays Music using a DC brushed motor for a speaker
Almost all small robots have a couple of DC motors to drive the wheels. This tutorial explains how to use those motors as speakers. Theory Basically a speaker … Read more
One thing most robots need is the ability to control motors. This circuit will work from 7.2V to 15V with PWM frequencies up to 25KHz and drive motors with a stall … Read more
Increase torque or reduce noise in DC brushed motors
By default, most Arduino pwm outputs are set to about 490Hz or 980Hz. These frequencies work quite well with small dc brushed motors but can cause unwanted noise or … Read more
Provides Rover 5 chassis with motor drivers, power supply and IR sensors
Introduction: The Explorer PCB was designed specifically for the 2 motor / 2 encoder version of the Rover 5 chassis. The Explorer provides all the basic features … Read more
Burn the bootloader or write sketches directly to the MCU
The Arduino and Arduino compatible boards all use a small program called a bootloader to take serial data from your computer and store it in the Arduino's memory. … Read more
A tutorial for calculating series resistance and reading LED data sheets
I've noticed that some people are uncertain how to calculate series resistance for a LED or when using a group of LEDs are uncertain about wiring them in series or … Read more
