SMART LED FLASHLIGHT – a tiny personal emergency Light sensing LED flashlight.

How it works: The flashlight turns on automatic for 60 seconds when it senses that the room is dark enough. To turn on manual light for additional 60 seconds you need to push the RST button. The Light sensing LED Flashlight is invaluable for emergencies such as power failures or blackouts. Step 1: ​The Flashlight is invaluable for emergencies such as power failures or blackouts. I have assembly several Flas ...

Easy Planter

This project was inspired by a position i was trying to get in monitoring plants, and thought it would be enough to impress the employer to hire me :) I have never been a particularly good gardener, mainly because of forgetting to water the plants, and not knowing if they were getting enough light. I hoped this project might help me take care of the plants better. The Easy Planter is able to monitor soil mo ...

One Channel InfraRed Remote Controller

One Channel Infra-Red Remote and receiver with onboard Relay provides normally open and normally closed output. The project based on PIC12F683 Microcontroller from Microchip , TSOP1738 used as Infra-Red receiver. Micro-controller decodes the RC5 serial data coming from TSOP1738 and provides high output if the data is valid. The output can be set Momentary or Latch using on board Jumper (J1) and closure. The ...

Maximize the Energy from Long-Life Batteries

Battery lifetime is a key consideration for the development of the wireless sensor nodes that will populate the Industrial Internet of Things (IIoT). In many applications, the sensor nodes will need to be installed in locations that are difficult to reach let alone service. The sensor nodes need to be autonomous in terms of energy because it is too costly and difficult to run power lines to them or to have ...

Fluke 15B+ WiFi – Introduction

Introduction One of the bad things about electricity is that it is mostly invisible: unless the voltages or currents are very high, it mostly flows invisibly through wires, it's existence only implied by a lighted up LED, a beeping speaker, an LCD that indicates something or another secondary effect. Normally, this is what we want: the invisibility of electricity makes it very easy to integrate it into any ...

Basics of the I2C Communication Protocol

So far, we’ve talked about the basics of SPI communication and UART communication, so now let’s go into the final protocol of this series, the Inter-Integrated Circuit, or I2C. You’ll probably find yourself using I2C if you ever build projects that use OLED displays, barometric pressure sensors, or gyroscope/accelerometer modules. I2C combines the best features of SPI and UARTs. With I2C, you can connect mu ...

The cheapest ESP8266 programmer!

Hi folks, now I'll teach you how to make your programmer to the ESP-01 and ESP-201, (perhaps serve with other models) using an Arduino UNO, a few cables and optionally a button and a slide switch, in my case I use them because I had available, with this programmer able to upload the Arduino sketches and any other firmware (AT, LUA, Espruino, etc). Okay, let's start, first do the following circuit. Optionall ...

Basics of the SPI Communication Protocol

When you connect a microcontroller to a sensor, display, or other module, do you ever think about how the two devices talk to each other? What exactly are they saying? How are they able to understand each other? Communication between electronics is like communication between humans. Both sides need to speak the same language. In electronics, these languages are called communication protocols. Luckily for us ...
