Controlling an HMC624LP4E RF Attenuator Using Arduino
I recently found a Hittite (acquired by Analog Devices in 2014) HMC624LP4E evaluation board gathering dust in my miscellaneous PCB […]
Interfacing HDC1050 with Arduino
Recently, I got my hands on TI‘s HDC1050 low power, high accuracy digital humidity/temperature sensor chip. The supply voltage of […]
TI MSP430G2 SPI Examples
In my earlier posts (1, 2, 3), I showed some examples of using the I2C protocol with TI’s MSP430 Launchpad. […]
Reading SHT21 Using TI MSP430 LaunchPad
SHT21 is a neat little temperature and humidity sensor from Sensirion and I have used it in a couple of […]
I2C Multiplexer Shield Testing
I built an I2C multiplexer shield using an Arduino prototyping shield from SchmartBoard a couple of weeks ago. The shield […]
MSP-EXP430G2 I2C Master Examples
Last week, I mentioned that in order for the I2C bus to function correctly when using the MSP430 Launchpad you […]
MSP-EXP430G2 I2C Issue Resolved
I was experimenting with I2C using my TI MSP-EXP430G2 Launchpad and ran into some issues. For a while, I could […]
Interfacing MMA8453Q With Arduino
MMA8453Q is a rather inexpensive accelerometer. It is significantly cheaper than many other 3-axis accelerometers (such as the popular LIS3LV02DL) […]
Interfacing DS7505
The DS7505 digital thermometer and thermostat is a very versatile temperature sensor. It offers 9 to 12-bit digital temperature readings […]
Temperature/Humidity Data Logger — Trial Run
I built a rather generic I2C data logger a few weeks back. As I mentioned in my earlier posts, it […]
I2C Data Logger Using ATmega328p and DS3232 – I
There is a popular data logger shield out there designed for Arduino using a DS1307 real time clock chip. And […]
A High Current TRIAC Controller Using Arduino
One of the goals in my previous timer project was to achieve the ability to control multiple electronic devices using […]
Clock Synchronization Via I2C (TWI)
When I was doing the clock/stop watch project last month, I mentioned that I intended to add I2C (TWI) communication […]
A Clock/Stop Watch Based on BQ3287
Over the past couple of weeks, I have been experimenting with BQ3287, a real time clock module from Taxes Instruments. […]
