$10-30 CAD

Paid on delivery
I want a digital clock, where each digit is expressed as a binary number, displayed with LEDs. I want a design of the circuitry, including wiring diagram and names of chips. I want it designed to take AA batteries, and it should last as long possible. Please include a calculation of how long the batteries will last. Inputs: - a button to set the time by incrementing the hours. - a button to set the time by incrementing the minutes. - a switch to switch between 12 and 24 hour time Outputs: - 2 LEDs to the hours tens column. - 4 LEDs to the hours ones column. - 3 LEDs to the minutes tens column. - 4 LEDs to the minutes ones column. If you choose to use a programmable chip like an ATTiny, I can do the programming.

I have long experience with 8-bit , 16-bit and 32-bit micro-controllers. I work with Microchip (PIC) , Atmel (AVR , SAM) , ST (STM) , TI (MSP) , Nordic (nRF52), and NXP (LPC) micro-controllers. I use KEIL IDE , Atmel Studio , Code Composer Studio and MPLABX IDE . I deliver tested , neat and well-commented code that can be reused or modified for future development. You can see samples of my previous work on my portfolio and youtube channel. More to be discussed once you contact me . BR, M.T.

Hi, I built an LED Clock a year ago. It does exactly what you are looking to do. With regards reducing power consumption, I found the addition of a potentiometer to control the amount of current going to the LED circuit helps to reduce the current consumption. The biggest problem is keeping an accurate time. Using an internal RC clock in the ATTiny can cause the loss of about 2 minutes per day, this accumulates over days to make it much worse. I know you mention the ATTiny, unless you use an external LED Driver, which is probably a bit excessive and expensive, it would probably be easier to use an ATMega (like the ATMega328p) to control the 13 LEDs, 3 buttons, 1 potentiometer input and a PWM output to limit current consumption to LEDs. With regards the circuit diagram, are you only looking for a wiring diagram? Are you looking for a bread board layout diagram or will you be building this yourself from the wiring diagram? Will a Fritzing wiring diagram suffice? The project is straightforward and I don't see any real issues with the design. I look forward to hearing back from you and I look forward to the opportunity to work with you. -Mike
