To describe the performance or work of electronic schematic of Light Detector Robot as like in figure 1 above we can divide into three parts. In sensor, Microcontroller, and driver dc motor. In this part we use LDR as light detector or sensor. LDR will.... -
The module costs GB38. 00 and the transducer costs a further GB17. 00. In fairness, the Polaroid module does the job it was intended to do, which requires the range, but that job is not to provide the eyes of a small robot. The circuit is designed to be low.... -
Edge Avoider Robot (EAR) is a mobile device, which senses and avoids the absence of surface below it.... -
A Mobile Controlled Robot is a mobile device, which provides wide-range of wireless control ability to your robot unless your cell phone gets out of signal.... -
An obstacle avoiding robot is an intelligent device, which can automatically sense and overcome obstacles on its path. It is developed without micro-controller in order to eliminate critical circuits, difficult programming etc. All you want to do is to just.... -
Bridges allow your robot to control high current motors. They literally "bridge" between the low-current logic circuitry of your robot`s brain to the high current demanded from the motors. Many, but not all, use the common "H" arrangement of control.... -

Do-it-yourself Atmel STK505 replacement board allows programming of ATtiny84 and ATtiny861 (14-pin and 20-pin) AVR microcontrollers with the STK500 development kit. Article also describes an ATtiny 8-pin quick setup connector board.... -
A schematic that details the connections to the Clare IXDI404PI chip that is both the brains and the brawn of the Back-And-Forth robot that you can make yourself.... -
Schematic of Big Trak`s motor driver circuit. The toy includes 9112 and 9113 transistors (and sometimes 2N6715) because the 75494 chip can`t supply enough current to run the Big Trak`s motors by itself.... -
Schematic, breadboard photo, parts list, and results of several transistor variations on the classic bipolar hbridge motor driver circuit.... -
The real usefulness of the SR latch comes during input switch transitions. Let`s assume the input switch is a break-before-make and the switch starts in the up position. From the prior analysis, the inputs values when the switch is up are low, low, high,.... -
Describes reading a thermistor using an Atmel ATtiny45 or ATMega168 microcontroller to drive two fans to cool a PC installed in a kitchen cabinet. Include a table for converting the BC1482 resistance to Fahrenheit.... -
The Flip-Flop Robot drives forward until it hits an obstacle, and then reverses until it hits another obstacle. This back-and-forth process continues indefinitely. By limiting the functionality to this very rudimentary behavior, it can be generated from an.... -
The simplest solution for implementing joystick control for a robot would be to program the actions in software in a microcontroller. But, since many readers prefer off-the-shelf parts, this circuit is going to be made with diodes, resistors, transistors,.... -
Most of my circuits still use 5 V regulated power for the chips, because 8-bit microcontrollers run faster and some sensors require 5 V. Since 5 V is more than enough for even a white LED, I`m not concerned with the voltage needed by a particular LED in use..... -
The laser-pointer detection circuitry is able to determine when a laser light is aimed at a particular photosensor. If the laser is aimed at the top sensor, the comparator chip outputs on . If the laser is aimed at the bottom sensor, the comparator chip.... -
To understand how the 74AC14 PWM circuit works, let`s zoom in on the section of the schematic containing the trimpot, diodes, capacitor, and the first inverter logic gate. The capacitor is empty (discharged) when the power is first applied to the circuit..... -
Discrete blinking LEDs are convenient, but the blink rate and blink duration are not configurable. I tried goofing around with using transistors, resistors, and capacitors to alter the blinking LED. In the end, I had so many extra electronic components that.... -
One of the first lessons that an electronics student learns is that an LED provides light from current flow. But, did you know that an LED put in backwards provides current flow from light Yes! It`s true. Hook up a high-quality ultra-bright red LED by itself.... -
This circuit adds a datasheet-compliant trigger signal, reversed polarity protection, optional test button, and optional battery operation. U1 L601E3 or MAC97A8 triac. 400 V, 1 A. When U1 is enabled, the + and - wires of the flash are electrically connected,.... -
To obtain the power supply graphs on the previous page, I didn`t stand outside for two days straight measuring the power sources with a voltmeter. Instead, the circuit itself is able to independently monitor the power sources with the addition of a few.... -
Need more current If you`ve got a larger motor waiting to be used, the Pololu High Current Motor Driver Board 14A 6V-16V is just what you need. Connect three digital lines to your microcontroller (five if you want error condition feedback), and you`re ready....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
