STM32 Timers

Posted on by

Everything related to digital electronics is related to time. Timer, counter, frequency, pulse width, clock and time are the most common words one may find in this arena. Microcontrollers just like humans need heart-beats and these come from clock sources. Apart from system clock, timers are clock sources that can be used as heart-beats for various applications. All modern micros are embedded with timer-counter modules and generally they are used for generating time bases, counting pulses, measuring time periods of waveforms, generating pulse width modulation (PWM) signals, triggering external devices and timing special events. STM32 micros have several timers designed

IoT temperature monitoring device

Posted on by Leave a comment

This temperature monitor IoT device uses ESP8266 and DS18B20 to report a remote temperature measurement to a mobile app and also sends an email to the user if the temperature goes below a set threshold. To complete this project you will have to create three things Hardware – Basically you have to hook up the temperature sensor to the ESP8266 board and upload the Arduino code. Cloud device – Create the logic that drives the decision making using the IC2Cloud platform www.ic2cloud.com Mobile App – Create the mobile App using AppInventor to monitor and control your temperature appinventor.mit.edu This project can

ESP8266 controls an AC outlet for lamp

Posted on by Leave a comment

Gary shares his ESP8266 controlled on/off switch for a lamp. The first step is to find a case to house the parts in. I had an old TP-link router case that I used. It already had a two prong spring out 110v connections but any box will work. When planning your boxes figure out how your going to get the AC in and out of the box. A stop at your local bigbox hardware store should give you lots of idea. At a minimum a deepwall outlet/switch box will work but use your imagination. My project only uses 2 wire
