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 the precise time signal generated by the RTC chip (bq3287). For electronic devices using up to a couple of amperes, a relay should be more than capable to handle the load. But for high voltage and high current home appliances such as water heaters (typically 240V, 20 to 30 A), the relay solution becomes much more expensive and less reliable.

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 functionality so that I could get time from this clock and use it as timer signal to control other electronics. Continue reading ‘Clock Synchronization Via I2C (TWI)’ »
