It used to be that there wasn’t a problem on the average car that couldn’t be solved with a nice set of wrenches, a case of beer, and a long weekend. But the modern automobile has more in common with a spaceship than those vintage rides of yesteryear. Bristling with sensors and electronics, we’re at the point that some high-end cars need to go back to the dealer for even minor repairs. It’s a dark time for ...

In this instructable I am going to show you how to build a weather station that logs the information that it collects on a sd card. Step 1: If You Prefer a Video Here It Is Step 2: Get All the Parts You need, 1 Arduino board, I used the pro mini 1 dht sensor I used the dht 22 1 10k resistor 1 SD card or micro SD card with matching board 3 feet on wire 3 wire cable (you will use this to connect your dht sens ...

I will show you how to send emails from any ESP8266 wifi module using Gmail server. This instructable relies on Arduino core for ESP8266 WiFi chip, which makes a self-contained microcontroller from it (no need of AT commands and master devices). You can connect sensors and get notified by email about changes. Before we begin Required hardware: Any ESP8266 (I'm using ESP8266-07 ebay link). In my case USB UAR ...

During experiments with digital voice mode in hamradio I discovered a nice project describing an adapter for D-Star, DMR and other digital modes based on an Arduino Due and a little PCB to be put on top. This unit is called the Multimode Digital Voice Modem or MMDVM (see [1]). It seems that this is getting quite popular because hard- and software is Open Source. The units can be ordered from Bruce, VE2GZI f ...

Wouldn't it be nice if you could start warming up the camp before you leave the house? How about using Alexa to do it for you! Things used in this project Hardware components Amazon Alexa Echo Dot × 1 Arduino MKR1000 × 1 ControlEverything.com Relay Shield for Particle Photon I²C 8-Channel SPDT 10-Amp This one says its an i2c relay shield, the one I used was just an opto coupler relay shield with 8 input pin ...

Position control using wifi from a smartphone sounds too good to be true? Do it with MKR1000. Things used in this project Hardware components Arduino MKR1000 × 1 Hand tools and fabrication machines 3D Printer (generic) Story Many position control use steppers because they are easy to deal with and are cheap. RC servos are easy and cheap too, but they are limited to half revolution. Continuous rotation servo ...

If you are mainly involved in designing or repairing digital devices, a logic analyzer is more useful than an oscilloscope for tracing signal through circuits. However, does this mean you should rush out and buy a logic analyzer? The instruments from the leading manufacturers are too expensive for home use or startup businesses, and the low-cost alternatives don’t do what you want or have half-baked softwar ...

  Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC ad ...

After making the switch from AVR to STM32 microcontrollers, I redesigned my old 6-pin ICSP pogo-programming adapter for SWD. The new design allows programming with pogo pins or a small pin header soldered to the pogo pads for debugging, all with the same cable. The footprint uses surface mount pads only, so it can be placed on even the most compact board layouts. The ST-link adapter I designed a small PCB w ...

Among my recent electronics purchase spree was the amazing Teensy LC from PJRC. It has a nice ARM Cortex-M0+ processor, real hardware USB, and what’s the nicest part, an Arduino add-on called Teensyduino which enables easy programming with Arduino, but with support for many of the hardware features. Now I started playing piano a while ago, and just a few weeks ago bought a Pianoteq license to send notes via ...
