Robots look cooler when they have a sinister green glow. Better yet, when that glow exists for a functional purpose it’s even better! Here I show how to make a custom robot and use LED’s to not only enhance line following, but also make it work in the dark too. Step 1: The Mechanical Design […]

The PIC Ultrasonic distance meter works by transmitting a short pulse of sound at a frequency inaudible to the ear (ultrasonic sound or ultrasound). Afterwards the microcontroller listens for an echo. The time from transmission to echo reception lets you calculate the distance from the object. PIC Ultrasonic Distance Meter Specification Range ~5cm – 300cm

This robot is controlled by a visual basic program (through the serial port), and can move in three different velocities by a pulse width modulated (PWM) signal generated by a PIC microcontroller (16F877). The robot can be operated in two modes, “normal control” and “light tracker” modes. In the normal control mode, the robot can
*** There’s an updated version of this kit available at http://www.theledart.com/blog/store *** Responding to many requests, Aurora 9×18 Kit is now available, so this is the Instructable specific to building the kit. Please leave comments, especially tips for successful assembly. Step 1: Identify the Parts First, identify all the parts contained in the kit. Below is the
Two DIY micro-controller based USB connected electronic units which along with the Texas Instruments Analog System Lab Starter kit and a laptop permit you to conduct analog experiments anywhere. It would be wonderful if senior students and laboratory supervisors built these units so that they could be used in their laboratories by freshers. Aj-SigGen-PS

I discovered a flaw in the current design that will only allow the controller to work with a connection to the computer and not to a microcontroller. I’ve updated the schematic below and will fix the controller design. I’ve added a project file below that also includes the fixed schematic. If you look at the

There may be a lot of RGB LED Drivers out there, but this one is a bit different, its versatile, small, cheap, and is simple to control. A potentiometer with built in switch is used for the controls. A quick press, switches between color cycling and solid color select modes. Pressing in on the dial and
