Line follower is an autonomous robot which can detect a specific colored line painted on a surface of different contrast, such as white on black. In this project I used infrared transmitters and receivers to track the black strip on white surface. Due to the difference of infrared reflection on black and white surfaces, it […]

RF Thermostat
This project described the fist part of the following project: An RF Thermostat as described in this Instructable An RF Panel Relay, described in the following Instructables:https://www.instructables.com/id/RF-Panel-Relay/ Some time ago I posted an Instructable about controlling an Infra Red panel with a remote control, see: https://www.instructables.com/id/Infra-Red-Panel-R… The project described in this Instructable was started because […]
RF Panel Relay
This project described the second part of the following project: An RF Thermostat as described in the following Instructurable: https://www.instructables.com/id/RF-Thermostat/ An RF Panel Relay, described in this Instructable For an introduction on this project first read the description of the RF Thermostat. In short the RF Panel Relay has the following functions: Decode an RF message […]
IR Remote Controlled Home Automation Using PIC Microcontroller
In this project, we are going to use a PIC microcontroller to remotely control few AC loads by just using an IR remote. Here we designed it on PCB using EasyEDA’s online PCB designer and used their PCB designing services to order the PCB boards as shown in the subsequent section of the article. At the end […]
Reaction Speed Timer
Many, many years ago – when I was young – I visited the Evoluon in Eindhoven, The Netherlands. At that time it had all kind of technical stuff you could see and you could play with. Nowadays it does no longer exists in that form since the Evoluon has changed into a conference center. One […]
Simple 3 Button On-off With 12f629 (mikroC)
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; ////// […]
How to Create a Garage Door Proximity Sensor
If you don’t have a reverse backup radar system in your car, or if you park forward in your garage, you probably know this feeling of “am I too close, am I gonna hit the wall??”. There are a lot of ways to resolve this issue, but if you like tinkering with electronics and writing […]
Intelligent access control based on STONE TFT LCD and ESP32
Brief Introduction Smart home is becoming more and more common with the development of technology, this article will focus on the security aspects of the intelligent access control project. This article uses STONE’s touch screen to send commands to the MCU to control the relay and MFRC522 module. The principle of card reading: by driving […]
WiFi Car Using NodeMCU
We have build car using many transmission technologies. But what about a WiFi Controlled Car? Actually speaking..Wifi is till now the most promising technology and engineers are using that tech to improve it more and more. This tech is most popular today and will remain for decades.Low power WiFi have also been developed.So let us […]
Tea Light Charger Monitor
Some time ago I bought some Electric Tea Lights that are charged using a wireless charger. This charger has a power LED that shows when the Lights are charged. After 10 hours of charging the charges switches off. It seemed, however, that there is an issue with the charger since the power LED that shows […]
