Step 1: COMPONENTS REQUIRED Bluetooth module (HC-05) AT89S52/C51/S51/C52 microcontroller Relay Driver ULN2003A Relay Resistances and capacitors as circuit diagram depicts(below) power module(if the input is more than 5V or else not necessary) IC 7805(5V voltage regulator) 1000uF capacitor 10uF capacitor led and resistance(as per convenience so that led doesn’t get damaged) IMPORTANT NOTE: USE 11.0592MHz […]
Have you ever wanted to make a line following robot but the infrared sensors were too expensive for you? Do you want to upgrade the robot in my other instructable? Well this instructable comes in two stages, Stage 1 is the prototyping stage, where you build the circuit on the bread board and debug it […]
Introduction: Okay, I cheated. Any similarities between previous Instructables uploaded by me and the graphics, pictures, text and / or programming code is purely intentional. It certainly made putting this one together a whole lot easier. This Instructable is my Arduino version of the Rock Paper Scissors Lizard Spock game devised by Sam Kass and […]
a simple 3 buttons on-off with pic12f629. it’s written with MikroC Step 1: The Code… start the code with ”int”———————————————————- int x0,x1,y0,y1,z0,z1; ////// with this the GPIO outputs could stay on or off void main() { GPIO = 0x00; ////// all outputs are 0 CMCON = 0x07; ////// Disable CMCON PORT TRISIO = 0b00111000; ////// […]
This is a funny project that makes our plants “talk” to us. It’s very simple and you can create it in few hours. We use a sensor to read the soil moisture of our plant and a led matrix to dislay how the plant “feel”. You can use an ATtiny85 as a microcontroller. Step 1: […]
In the previous instructable I showed you how to get started with IoT using the nodeMCU, in this instructable I will be featuring the Particle Photon which is an easy to use IoT device to get started with designing IoT projects. The particle photon is smaller than the nodeMCU and features STM32 ARM Cortex M3 microcontroller on […]
How often do you ever forget to feed your fish? Well, for me I don’t forget that much. I just couldn’t go out town for a couple of days and also be ridiculous if I should bring my tank along. When I won a Sparkfun RedBoard from Sparkfun Analogy Contest, this was the first project […]
This here is my first Instructable project. So you want to get started with NodeMCU? Well, I’m here to share with you.Today, I’m going to show you how to get started with NodeMCU. Let’s GO ! NodeMCU has on board ESP8266-12E makes the board suitable for IoT (Internet Of Things). In this Instructable I will show you […]
Almost inevitably, when I try to climb the same route I’ll forget exactly what sequence of holds they used and end up following a slightly different path. Even when I remember exactly which course to follow, I’ll still wonder whether I’m doing it as quickly as the previous climber. Yes, I know that skill in […]
This was originally going to be a tutorial on how to hook up a pumpkin to the internet so that the lights inside it could be controlled via twitter, text message, motion or more. To get started I carved a pumpkin for the first time in 20 years. Needless to say I was proud of […]
