DIGITIZE YOUR SLIDE DECK WITH THIS ARDUINO POWERED SLIDE CAROUSEL

DIGITIZE YOUR SLIDE DECK WITH THIS ARDUINO-POWERED SLIDE CAROUSEL

If you’re above a certain age, you probably remember the atmosphere of a pre-Powerpoint 35 mm slide show. The wobbly screen being unrolled, the darkened room, the soft hum of the projector’s fan, the slightly grainy picture on the screen and that unmistakable click-whoosh-clack sound as the projector loaded the next slide. Nowadays you’ll be

Arduino Dot Matrix LED

Using a Dot Matrix LED with an Arduino and Shift Register

The Siemens DLO7135 Dot matrix LED is one amazing piece of optoelectronics. It’s billed as a 5×7 Dot Matrix Intelligent Display (r) with Memory/Decoder/Driver. Along with that memory, it’s got a 96-character ASCII display set with upper and lower case characters, a built-in character generator and multiplexer, four levels of light intensity, and it all

BUCK BOOST BATTERY CHARGE CONTROLLER WITH MPPT AND I2C

BUCK-BOOST BATTERY CHARGE CONTROLLER WITH MPPT AND I2C

The LT8491 from Analog Devices is a buck-boost switching regulator battery charge controller that implements a constant-current constant-voltage (CCCV) charging profile used for most battery types, including sealed lead-acid (SLA), flooded, gel and lithium-ion. Applications are expected to include solar powered battery chargers (see simplified schematic above), multiple types of lead-acid battery charging, Li-ion battery chargers, battery-equipped industrial or
