Wireless PICAXE-based water tank level sensor

Over the last few months I have prototyped and built a water tank level sensor for my 9000L rain water tank. The design is based entirely on Silicon Chip’s PIC-Based Water-Tank Level Meter, but instead of programming PICs, I prototyped using an arduino, and built the final version using PICAXE microcontrollers. The sensor consists of two components, each housed separately and joined by shielded cable. Press ...

RFM12 – Wireless Transceiver Module Demo using pic microcontoller

Description Hardware Software Running the RFM12 Demo Download Links Description This project shows how to do wireless communication with the RFM12 tranceiver modue in combination with a PIC microcontroller. The RFM12 is a low costing ISM band FSK transceiver module. There are different module variants available which support different frequency bands: 315/433/868/915MHZ. The module has an SPI interface for ...

DIY Bluetooth RC Car

Last year I started a project to convert my (then) four-year old’s busted Radio Controlled (RC) car into Bluetooth controlled one which could be driven using a smart phone or tablet. The original car, modeled after a “Fast and Furious” Nissan Silvia, was a pretty basic RC with 2-channel on-off (non-proportional) style controls, and while Micah enjoyed playing with it I thought it might be nice to pimp it ou ...

SL4A Bluetooth Controller

Having had a bit of an unproductive Easter break I think it’s about time I got back to posting the concluding details of how the transmitter for the Bluetooth RC was implemented. I built the PIC-based motor and servo controller before acquiring the BlueSMiRF module so initially I wrote the following simple Python script based on the PyGame module to control the board via the direct (wired) serial connection ...

2meter (144MHz) amateur radio transceiver

I designed , built, tested and operated a 2m hamradio transceiver that includes all the necessary circuitry, in particular the voltage-controlled oscillator (VCO) + phase-locked loop (PLL) for frequency synthesis, low noise amplifier (LNA) for the receiver front-end, power amplifer (PA) for the radio frequency (RF) output stage and PIC based micro-controller (PIC) with serial interface to computer desktop. ...

Infrared Remote Control with Microcontroller

This little project will demonstrate how you can use NEC IR protocol based TV, DVD or VCR remote control to control you home appliances like fan bulb or virtually anything. There are lots of projects out there to accomplish this task but i have to write my own code because of too many requests on IR infrared Remote Control Relay Board with PIC12F675 Microcontroller. There are a number of consumer Infrared p ...

Top 5 Wireless Ways to Communicate with your Controller

One of the strongest trend we have seen this year at CES2015 is, as you can imagine easily, the IoT (Internet of Things) development. Consequently, the most important component needed is the “connection and communication” module that enables the remote interaction between the device and “the community” via internet. Here we will sum up the various possibilities you can use to connect your controller using d ...

Prometheus/Pandora’s Box using PIC12C508 microcontroller

Prometheus/Pandora's Box Some of you monkeys out there think you can PWN me. You need to be Spanked. Here is an obfuscated ultraminimalized Monolith for you. It is enlightening and harmless, except to the devil, who really hates it, because I'm letting you have it (for "free"). You're curious. So Make it, if you have tools. GET PARTS This is easy. You need: -a PIC12C508 or 509 or anything compatible or be a ...

Object Detecting Android Mobile Phone Controlled Bluetooth Robot Using PIC Microcontroller 16F877A

Last time we had a project on Arduino robots with Bluetooth and Android, and in that one our readers Mr. Paul asked how he can make an obstacle avoidance robot. So today I came up with another engineering project for electronics and communication students, Android and Bluetooth controlled robot using PIC Microcontroller with object detecting capability. After installing MikroElectron’s Robot Control App fro ...

Universal Serial Infrared Receiver. using pic microcontoller

You can use this Universal Infrared Receiver (UIR) project to control your PC:  Starting Windows programs,  setting the Windows volume control,  even moving the mouse around the screen! All at the touch of a button - with your TV remote control in fact! It uses a PIC microcontroller to characterize the demodulated infrared signal and then transmit it as a serial data stream to the PC. Software running on th ...
