Revised version of the PIC12F microcontrollers breakout board

The 12F series of PIC microcontrollers are handy little 8-pin devices designed for small embedded applications that do not require too many I/O resources, and where small size is advantageous. These applications include a wide range of everyday products such as hair dryers, electric toothbrushes, rice cookers, vacuum cleaners, coffee makers, and blenders. Despite their small size, the PIC12F series microcontrollers offer interesting features including wide operating voltage, internal programmable oscillator, 4 channels of 10-bit ADC, on-board EEPROM memory, on-chip voltage reference, multiple communication peripherals (UART, SPI, and I2C), PWM, and more. This is a revised version of the previous

Support us by preordering TrH Meter kit on Tindie

We are now accepting pre-orders for the TrH Meter kit through Tindie’s fundraising program, a new feature that they announced a couple days ago. Our target is to receive 20 orders by Dec 31st. So if you pre-order it now, you will get a complete TrH Meter kit for a discounted price of $25 and a thank you note from us for your support in making this funding campaign successful. You will receive a preprogrammed PIC16F688 microcontroller with the kit, which means the kit is ready to go right out of the box. “TrH Meter is a DIY microcontroller-based indoor thermometer

TrH Meter: A DIY indoor thermometer plus hygrometer with adaptive brightness control implemented to 7-segment LED displays

This project is about building a microcontroller-based digital room thermometer plus hygrometer that displays temperature and relative humidity on 4 large (1 inch) seven segment LED displays which adjust their brightness level according to the surrounding illumination. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor (LDR) and uses that information to adjust the brightness of the display. An inexpensive DHT11 sensor is used to measure temperature and relative humidity. The microcontroller used in this project is PIC16F688, and it runs at 4 MHz clock generated from its internal source. A
