Electrical Subsystem Schematics

The goal of the electrical design was to streamline an automatic shift control while keeping manual user input in a fast, user-friendly way. The electrical design was driven by the complexity required by the mechanical system. The system takes in rider input in the form of a throttle position sensor, shift pushbuttons, and mode selector. It also takes in other input that the rider doesn't have direct contro ...

How to work with inbuilt ADC Module of PIC18F4550

A microcontroller, a digital device, can read, execute and transmit only digital signals. On the contrary, the outputs of the most of the transducers are analog in nature. Thus it is hard to interface these transducers directly with controllers. Analog-to-digital convertor (ADC) ICs are one way to make the analog input compatible with the microcontroller. Using an external ADC adds complexity to the circuit ...

IR-Sensor Circuit and Interfacing with PIC Microcontroller

An IR sensor is an electronic device, that produces in order to detect some parts of the environs. An infrared sensor can measure the heat of an object as well as detects the motion. These sensors are used to measure only IR radiation, rather than producing it that is called as a passive infrared sensor. Generally in the IR spectrum, all the surrounding objects generate different form of thermal radiation.T ...

A Beginner’s data logger project using PIC12F683 microcontroller

It is a very simple data logger project based on PIC12F683 microcontroller. The microcontroller reads temperature values from a temperature sensor on a regular interval basis and stores them into its internal EEPROM memory. The recorded temperatures can be later transferred to a PC through serial interface. I originally published this project on electronics-lab.com last summer. I thought this could be a ver ...

Interfacing LM35 Temperature Sensor with PIC Microcontroller.

The are many cool sensors available now a days, ranging from IR distance sensor modules, accelerometers, humidity sensors, temperature sensors and many many more(gas sensors, alcohol sensor, motion sensors, touch screens). Many of these are analog in nature. That means they give a voltage output that varies directly (and linearly) with the sensed quantity. For example in LM35 temperature sensor, the output ...

Digital Barometer using PIC Microcontroller and MPX4115A Pressure Sensor – XC8

The Motorola MPX4115A is an atmospheric pressure sensor powered by 5V and delivers and output from ~0.25V to ~4.75V based on the pressure detected at room temperature (25°C). The device provides a linear output based on pressure. As the pressure rises, the output voltage of the sensor rises as well with ~0.25V represents <15 kPa pressure relative to a vacuum and ~4.75V represents >115 kPa. Note that  ...
