This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...
Battery-charger-control designers face a fundamental choice: to use a part from the rich selection of dedicated charge-control ICs available from many vendors or to use a programmable microcontroller.
The objective of the project is to use microcontroller circuits to replace everything inside an RC car, leaving the body and motors behind. A pair of 418MHz transmitter/receiver was used for the ...
