This voltage value will be converted by the PIC ADC peripheral and passing the converted numeric value as the delay argument on the _delay_ms() function inside the loop. This program basically works by displaying the running LED attached to RC0, RC1, RC2 and RC3 ports on the PIC16F690 microcontroller the speed of the running LED is controlled by the voltage value reads from the user’s trimport on the port RA0.

On this tutorial we will learn how to program the Microchip PIC microcontroller for reading the analog signal using HITECT PICC-Lite C compiler. Therefore before we can use all of these cool sensors we have to learn the basic of how to use ADC peripheral inside the PIC 16F690 microcontroller. Today many manufactures produce sophisticated sensors for specific task such as sharp GP2D120X is use for distance measurement, National Semiconductor LM35 for precision centigrade temperature sensor, HS12 humidity sensor from GE, TGS2442 carbon monoxide gas sensor from Figaro and many more. Some of the basic sensor such as LDR (Light Dependent Resistor) is used for measuring the light intensity or NTC (Negative Temperature Coefficient) a special resistor for measuring the temperature. Usually we use the electronic sensor to convert the analog value to the voltage level value. The ADC is one of the important features that enable us to digitize our analog world.

Please reference the quick start guide for each of the associated communication technologies, as they generally all work as protocol converters to convert data to serial communications at 115.2K baud.The PIC16F690 microcontroller is one of Microchip midrange 8-bit microcontroller that has a build in 10-bit resolution of Analog to Digital Converter (ADC) peripheral. This product has been updated to support many communication technologies. Built-In Pull-Up/Down Resistors keep the inputs quiet. A/D Inputs are also useful for reading light level sensors, thermocouples, switch closures, or just about any other kind of sensor you can think of.
This is particularly useful for reading temperature sensors (one temperature sensor is built into the board, shared with analog input number 8). A/D ConversionĪnalog to Digital Conversion allows you to read voltage levels from 0-5 volts using 8-bit or 12-bit resolution. You can assign 16 timers to any of the 256 relays, and set the timers to go off after the duration has expired.

You can send commands to activate relays, deactivate relays, control all the relays at one time, plus you can send commands that tell a relay to turn on for a few seconds, minutes, or hours. All relays are electronically latched, simply send a command to turn the relay on, send a different command to turn the relay off.
