ESP8266 Temperature Logger using PIC16F887

ESP8266 Temperature Logger using PIC16F887

The project ESP8266 Temperature Logger using PIC16F887 is built up using a PIC16F887 microcontroller (MCU), ESP8266 WiFi module, and a ThingSpeak API. Previously, we posted Arduino and ESP8266-based webservers and this project is somehow similar. Introduction to ESP8266 Temperature Logger using PIC16F887 Here is a PIC16F887 microcontroller and ESP8266-based temperature logging system. The project; ‘ESP8266 Temperature Logger using PIC16F887 monitor’s the temperature of the vicinity simultaneously and provides details of the information collected. Well, the project also incorporates a modern concept; ThingSpeak which ensures safe storage and retrieval of data from…

Elementary Database Management System using C

Here is a menu driven program for elementary database management system using C. There is a provision to Add, Modify, List and Delete records, the operations that are imperative in any database management. Following comments would help you in understand the program easily: Addition of record must always take place at the end of existing records in the file, much in the same way you would add new records in a register manually. Listing records means displaying the existing record on the screen. Naturally, record should be listed from first…

A small, cheap, reliable device is making its way into technology. We call it the ESP8266 Wi-Fi module which has reached almost everywhere. However, the fact that its related information on datasheets and documents are provided in the Chinese language; Mandarin makes the implementation process complicated. As a solution, people have opted for the ESP8266 community forum which discusses issues users of this module tackle while programming this module. This small wifi-chip ESP8266 constitutes a built-in 32-bit low-power CPU. The chip itself can be employed as a stand-alone device or…

Recently we have been posting Robot projects. And, here comes another one; Robocar with gesture-controlled or you can say Arduino Gesture Controlled Robot. Like other projects, it also employs remote control. The project Arduino Gesture Controlled Robot is concerned with the design of a robotic car that can be moved in any direction just like a car does. Motion is recognized by the accelerometer and then it generates command signals to operate the robot as required using RF as a mediator. Likewise, the Robocar has inbuilt obstacle detectors and avoids…

PIC16F877A Based Dual Mode Robot

receiver circuit of dual mode robot

Previously we presented ‘Arduino Based RF-controlled Robot’. This project ‘PIC16F877A Based Dual Mode Robot’ includes slight modifications to that project. This Robot has inbuilt features to identify and avoid obstacles on its way and can be easily controlled with the help of RF-based remote control. The project can be used as a base to build up projects like automatic vacuum cleaners along with some modifications. The best part in that context is that artificial intelligence cleans the floor on its own and we can guide the robot to clean areas…

Automobile Brake Failure Indicator

automatic brake failure indicator circuit

Almost 40% of accidents occur because of brake failure issues. With early identification of this condition, we can reduce the accident rate. The project ‘Automobile Brake Failure Indicator’ is the solution to this global issue. You might be wondering how this project is responsible to lower the accident rate. Well, this indicator circuit keeps an eye on the condition of the brake at regular intervals and provides an audio-visual indication of the situation. The project includes two LEDs and a piezo buzzer as indicators. Under normal circumstances when the brake…

Arduino Based Music Player

arduino based music player

The project posted here is of simple music player system based on Arduino uno board and SD card module. As we all know that Arduino can deal with digital signals or square signals only if we wish to work with sine waves we have to use further processing circuits. Previously we had posted Tune Player using Arduino for demonstration of using PWM pin of Arduino. The audio signal is sine wave thus we have used PWM pin and OP-amp for audio output. In order to generate a pure audio signal…

Arduino and RF Controlled Robot

receiver circuit of arduino and rf controlled robot

Arduino and RF Controlled Robot ‘ROBOT’, as you know were introduced much earlier in the fifties. People could not afford those massive devices because of the cost they were tagged with. But now, to make it available to common people as well, our team developed a robot that is based on a simple platform like Arduino. Due to the fact that it uses RF remote control, using this robot is much easier. The omnidirectional robot works smoothly within a range of up to 100 meters. Adding more to its benefit,…

Telemetry System Troubleshooting

Telemetry system have become big business in recent years. In addition to the military applications, many commercial uses are being developed. Today’s telemetry markets range from remote reading of gas and electricity meter to credit card validation, security monitoring, token-free highway toll systems, and remote inventory control. After completing this article, you should be able to: Troubleshooting a radio-telemetry receiver Troubleshooting a radio-telemetry transmitter Receiver Problems Let’s start by looking at some possible receiver problems in figure 1. Since this receiver has a low-frequency IF amplifier, an oscilloscope can be…

Arduino Based Data Logger (Temperature)

arduino based data logger

The project described here is a simple Arduino Based Data Logger which can be used at any place where data is needed to be stored for further processing and monitoring. The project posted here basically store temperature, humidity with date and time in regular intervals on an SD card or a computer, or both. The wide range of operations and data rate of 12 samples per minute make this circuit more versatile and attractive at the same time. The data logging can be adjusted as per desire by changing the…
